Phonetic Description of Babbling in Danish Toddlers Born with and without Unilateral Cleft Lip and Palate

Longitudinal Speech Outcome at 5 and 10 Years in UCLP: Influence of Speech Therapy and Secondary Velopharyngeal Surgery

ObjectiveTo investigate speech development of children aged 5 and 10 years with repaired unilateral cleft lip and palate (UCLP) and identify speech characteristics when speech proficiency is not at 'peer level' at 10 years. Estimate how the number of speech therapy visits are related to speech proficiency at 10 years, and what factors are predictive of whether a child's speech proficiency at 10 years is at 'peer level' or not.DesignLongitudinal complete datasets from the Scandcleft projectParticipants320 children from nine cleft palate teams in five countries, operated on with one out of four surgical methods.InterventionsSecondary velopharyngeal surgery (VP-surgery) and number of speech therapy visits (ST-visits), a proxy for speech intervention.Main Outcome Measures'Peer level' of percentage of consonants correct (PCC, > 91%) and the composite score of velopharyngeal competence (VPC-Sum, 0-1).ResultsSpeech proficiency improved, with only 23% of the participants at 'peer level' at 5 years, compared to 56% at 10 years. A poorer PCC score was the most sensitive marker for the 44% below 'peer level' at 10-year-of-age. The best predictor of 'peer level' speech proficiency at 10 years was speech proficiency at 5 years. A high number of ST-visits received did not improve the probability of achieving 'peer level' speech, and many children seemed to have received excessive amounts of ST-visits without substantial improvement.ConclusionsIt is important to strive for speech at 'peer level' before age 5. Criteria for speech therapy intervention and for methods used needs to be evidence-based.

Diagnosis and Treatment of Speech Disorders in Children With a Cleft (Lip and) Palate: A State-Of-The-Art Overview

In children born with a cleft in the palate with or without a cleft in the lip (CP±L), velopharyngeal insufficiency may persist even after successful surgical closure of the palate. This results in speech disorders including both resonance and speech sound disorders. These speech disorders may have a severe impact on the children's speech understandability and speech acceptability which may, in turn, influence psychosocial well-being, quality of life, and inclusion into society. This article provides an overview of the most important speech characteristics per age group (ie, 0-4​​​​​​, 4-6, 6-12, and >12 y). In addition, a state-of-the-art overview of current practices in speech diagnosis and speech intervention is included.

How differences in anatomy and physiology and other aetiology affect the way we label and describe speech in individuals with cleft lip and palate

BACKGROUND

Speech in individuals with cleft lip and/or palate (CLP) is a complex myriad of presenting symptoms. It is uniquely associated with the structural difference of velopharyngeal insufficiency (VPI), together with a wide and heterogeneous range of other aetiologies which often co-occur. The nature of the speech sound disorder (SSD) including VPI may also change over the course of an individual's care pathway. Differences in terminology and approaches to analysis are currently used, resulting in confusion internationally. Additionally, current diagnostic labels and classification systems in SSD do not capture the complexity and full nature of speech characteristics in CLP.

AIMS

This paper aims to explore the different aetiologies of cleft palate/VPI speech and to relate aetiology with speech characteristic(s). In so doing, it attempts to unravel the different terminology used in the field, describing commonalities and differences, and identifying overlaps with the speech summary patterns used in the United Kingdom and elsewhere. The paper also aims to explore the applicability of current diagnostic labels and classification systems in the non-cleft SSD literature and illustrate certain implications for speech intervention in CLP.

METHODS AND PROCEDURES

The different aetiologies were identified from the literature and mapped onto cleft palate/VPI speech characteristics. Different terminology and approaches to analysis are defined and overlaps described. The applicability of current classification systems in SSD is discussed including additional diagnostic labels proposed in the field.

OUTCOMES AND RESULTS

Aetiologies of cleft palate/VPI speech identified include developmental (cognitive-linguistic), middle ear disease and fluctuating hearing loss, altered oral structure, abnormal facial growth, VPI-structural (abnormal palate muscle) and VPI-iatrogenic (maxillary advancement surgery). There are four main terminologies used to describe cleft palate/VPI speech: active/passive and compensatory/obligatory, which overlap with the four categories used in the UK speech summary patterns: anterior oral cleft speech characteristics (CSCs), posterior oral CSCs, non-oral CSCs and passive CSCs, although not directly comparable. Current classification systems in non-cleft SSD do not sufficiently capture the full nature and complexity of cleft palate/VPI speech.

CONCLUSIONS AND IMPLICATIONS

Our attempt at identifying the heterogeneous range of aetiologies provides clinicians with a better understanding of cleft palate/VPI speech to inform the management pathway and the nature and type of speech intervention required. We hope that the unravelling of the different terminology in relation to the UK speech summary patterns, and those used elsewhere, reduces confusion and provides more clarity for clinicians in the field. Diagnostic labels and classification require international agreement.

WHAT THIS PAPER ADDS

What is already known on the subject Speech associated with cleft palate/velopharyngeal insufficiency (VPI) is a complex myriad of speech characteristics with a wide and heterogeneous range of aetiologies. Different terminology and speech summary patterns are used to describe the speech characteristics. The traditional classification of cleft palate/VPI speech is Articulation Disorder, although evidence is building for Phonological Disorder and contrastive approaches in cleft speech intervention. What this paper adds to existing knowledge This paper explores the range of aetiologies of cleft palate/VPI speech (e.g., altered oral structure, abnormal facial growth, abnormal palate muscle and iatrogenic aetiologies) and attempts to relate aetiology with speech characteristic(s). An attempt is made at unravelling the different terminology used in relation to a well-known and validated approach to analysis, used in the United Kingdom and elsewhere. Complexities of current diagnostic labels and classifications in Speech Sound Disorder to describe cleft palate/VPI speech are discussed. What are the potential or actual clinical implications of this work? There needs to be a common language for describing and summarising cleft palate/VPI speech. Speech summary patterns based on narrow phonetic transcription and correct identification of aetiology are essential for the accurate classification of the speech disorder and identification of speech intervention approaches. There is an urgent need for research to identify the most appropriate type of contrastive (phonological) approach in cleft lip and/or palate.

Follow-up of expressive language and general development at 12, 18 and 36 months for children with no canonical babbling at 10 months

Little is known about the developmental trajectories in children who do not use canonical babbling (CB) at 10 months. The aim was to examine how speech, language, cognitive and motor abilities developed in children without CB. For 15 children identified as not having CB, consonant production, expressive vocabulary and general development were assessed at 12, 18 and 36 months from audio-video recordings. Twelve (79%) children still lacked CB at 12 months. At 18 months, six (40%) had parent-reported expressive vocabulary results below the 10th percentile, and two (14%) did not use dental/alveolar stops. The percentage of consonants correct for the group was at the level of peers at 36 months (89%, SD 0.17), but the group had fewer established target consonants than age norms. Most children had a small expressive vocabulary in comparison with Swedish age norms for younger children as well as with age-matched norms for other Nordic languages. The general development (Bayley-III) for three children (21%) who did not use speech was 1-2 SD below the average range in at least one domain (cognitive, language or motor), but the results for the whole group were within the average range. In conclusion, the heterogeneity in early consonant development in the study group resembles that of children in clinical groups with known risk for speech and language difficulties and the expressive vocabulary resembles that of children with delayed expressive vocabulary. For about one-fifth of the children, the absence of canonical babbling at age 10 months could be seen as an early sign of a more comprehensive developmental disability.

Stop Consonant Production in Children with Cleft Palate After Palatoplasty

The current study examined stop consonant production in children with cleft lip and/or palate (CP ± L) 2-6 months following palatal surgery.

Prospective comparative study.

Multisite institutional.

Participants included 113 children with repaired CP ± L (mean age = 16 months) who were participating in the multicenter CORNET study.

Parents of participants were asked to record approximately two hours of their child's vocalizations/words at home using a Language ENvironmental Analysis (LENATM) recorder. Four ten-minute audio-recorded samples of vocalizations were extracted from the original recording for each participant and analyzed for presence of oral stop consonants. A minimum of 100 vocalizations were required for analysis.

Preliminary findings indicate that at least one oral stop was evident in the consonant inventory for 95 of the 113 children (84%) at the time of their post-surgery 16-month recording, and 80 of these children (71%) were producing two or more different stops. Approximately 50% of the children (57/113) produced the three voiced stops, and eight of the children (7%) were producing all six stop consonants.

The findings of this study suggest that the majority of children with repaired CP ± L from English-speaking homes are producing oral stops within six months following palatal surgery. Similar to same-age children without CL ± P, voiced stops were more frequently evident in the children's inventories than voiceless stops. In contrast to findings of previous reports suggesting place of articulation differences, a somewhat comparable percentage of children in this study produced voiced bilabial, alveolar, and velar stops.

The Life Cycle of Orofacial Cleft Operations

Patients with cleft lip and palate must undergo various surgical interventions at appropriate times to achieve optimal outcomes. While guidelines for the timing of these operations are well known, it has not yet been described if national surgical practice reflects these recommendations. This study evaluates whether orofacial operations are performed in time frames that align with advised timing. Time-to-event analyses were performed using the 2012-2020 Pediatric National Surgical Quality Improvement Program database on the ages at time of orofacial operations. Outliers with an absolute Z-score of 3.29 or greater were excluded. Cleft lip (N=9374) and palate (N=13,735) repairs occurred earliest at mean ages of 200.99±251.12 and 655.08±694.43 days, respectively. Both operations clustered along the later end of recommended timing. 69.0% of lip versus 65.1% of palate repairs were completed within the advised age periods. Cleft lip (N=2850) and palate (N=1641) revisions occurred at a mean age of 7.73±5.02 and 7.00±4.63 years, respectively. Velopharyngeal insufficiency operations (N=3026), not including palate revision, were performed at a delayed mean age of 7.58±3.98 years, with only 27.7% of operations occurring within the recommended time frame. Finally, 75.8% of alveolar bone grafting cases (N=5481) were found to happen within the advised time period, with a mean age of 10.23±2.63 years. This study suggests that, with the exception of VPI procedures, orofacial operations reliably cluster near their recommended age periods. Nevertheless, primary lip repair, palatoplasty, and velopharyngeal insufficiency procedures had a mean age that was delayed based on advised timing.

Transcribing toddler vocalizations: comparison of a modified naturalistic listening approach with phonetic transcription

Previous investigations have demonstrated that naturalistic listening in real time (NLRT) can be used reliability to assess prelinguistic vocalizations and is less time-consuming than phonetic transcription. The current investigation was performed to examine the correspondence of syllable and consonant information obtained using a modified naturalistic listening in real time (NLRT) methodology compared to broad phonetic transcription for 20 toddlers with repaired cleft palate. A forty-minute vocalization sample was obtained for each toddler. Two listeners listened to each recording independently and coded the number of syllables and consonant types produced by each toddler using NLRT. Each recording was phonetically transcribed by each listener 2 to 16 months following the NLRT analysis. High reliability was evident between the modified NSRT method and phonetic transcription for identification of both syllables and consonants. Differences were evident in the actual number of syllables and consonants identified between the two types of assessment across the 20 participants. Possible explanations for those differences are addressed. The results of this investigation indicate that the modified NLRT procedure is a reliable method for determining consonant/inventories of young children. It is less labor intensive than traditional phonetic transcription and may be useful clinically when documentation of early sound development is needed to support early intervention decisions.

Inter-rater reliability in classification of canonical babbling status based on canonical babbling ratio in infants with isolated cleft palate randomised to Timing of Primary Surgery for Cleft Palate (TOPS)

Canonical babbling (CB) is commonly defined as present when at least 15% of all syllables produced are canonical, in other words a canonical babbling ratio (CBR) ≥0.15. However, there is limited knowledge about inter-rater reliability in classification of CB status based on CBR and inter-rater differences in assessment of CBR. We investigated inter-rater reliability of experienced Speech Language Therapists (SLTs) on: classification of CB status based on CBR ≥ 0.15, CBRs and the total number of syllables per infant used to calculate CBR.Each infant (n = 484) was video-recorded at a clinical site in play interaction with their parent as part of the randomised controlled trial Timing of Primary Surgery for Cleft Palate. Each recording was subsequently assessed by three independent SLTs, from a pool of 29 SLTs. They assessed the recordings in real time.The three assessing SLTs agreed in classification of CB status in 423 (87.4%) infants, with higher complete agreement for canonical (91%; 326/358) than non-canonical (77%; 97/126). The average difference in CBR and total number of syllables identified between the SLT assessments of each infant was 0.12 and 95, respectively.This study provided new evidence that one trained SLT can reliably classify CB status (CBR ≥ 0.15) in real time when there is clear distinction between the observed CBR and the boundary (0.15); however, when the observed CBR approaches the boundary multiple SLT assessments are beneficial. Thus, we recommend to include assessment of inter-rater reliability, if the purpose is to compare CBR and total syllable count across infants or studies.Trial registration number here: www.clinicaltrials.gov, identifier NCT00993551.

Better speech outcomes after very early palatal repair?-A longitudinal case-control study in Ugandan children with cleft palate

INTRODUCTION

Children born with cleft palate with or without cleft lip (CP±L) tend to use less oral pressure consonants and more glottal sounds in their babbling. The purpose of very early palatal repair (i.e., one-stage palatal closure prior to 6 months of age) is to make the palate functional before the onset of speech acquisition to reduce the anchoring of wrong patterns in the child's developing phonological system. As a result, less compensatory articulation errors are expected to be present. Currently, no detailed longitudinal speech outcomes after very early palatal closure are available. This study aimed to provide longitudinal speech outcomes in Ugandan children with CP±L who received palatal closure prior to the age of 6 months.

METHODS

Ten children with CP±L were assessed at a mean age of 5 and 10 years old. Speech understandability, speech acceptability, resonance, nasal airflow and articulation were perceptually rated by two experienced speech-language pathologists. Velopharyngeal function was estimated using the velopharyngeal composite score (VPC-sum). Information regarding speech therapy, fistula rate, and secondary (speech) surgery was collected. The outcomes were compared with the longitudinal outcomes of an age- and gender-matched control group of 10 Ugandan children without CP±L.

RESULTS

Speech understandability and acceptability improved significantly over time in the group with CP±L (all p's ≤ 0.05, all Z's > -2.43). At both test dates, significantly worse judgments were found for the group with CP±L compared to the control group for these variables and variables related to passive speech errors (all p's ≤ 0.05, all Z's > 2.49). A statistically significant difference with the control group was found for the presence of compensatory articulation errors at the age of 5 years but not at the age of 10 years, indicating a catch up by the children with CP±L.

CONCLUSION

Whether a one-stage palatal closure prior to the age of 6 months is more favorable for speech outcomes compared to one-stage palatal closure at 12 months is still not clear. Speech of the children with CP±L improved over time, but significantly differed from the control group at the age of 5 and 10 years old. Limited access to health care facilities and possible influence of malnutrition on wound healing need to be considered when interpreting the results. Whether palatal closure prior to the age of 6 months is transferable to other countries is subject for further research, including both longitudinal and prospective designs with larger samples.

One Size Doesn't Fit All: A Pilot Study Toward Performance-Specific Speech Intervention in Children With a Cleft (Lip and) Palate

PURPOSE

Speech-language pathologists usually apply a "one size fits all" approach to eliminate compensatory cleft speech characteristics (CSCs). It is necessary to investigate what intervention works best for a particular patient. This pilot study compared the effectiveness of two therapy approaches (a motor-phonetic approach and a linguistic-phonological approach) on different subtypes of compensatory CSCs in Dutch-speaking children with a cleft (lip and) palate (CP ± L).

METHOD

Fourteen children with a CP ± L (M _age = 7.71 years) were divided into two groups using block randomization stratified by age, gender, and type of compensatory CSC. Six children received intervention to eliminate anterior oral CSCs (n = 3 motor-phonetic intervention, n = 3 linguistic-phonological intervention). Eight children received intervention to eliminate non-oral CSCs (n = 4 motor-phonetic intervention, n = 4 linguistic-phonological intervention). Each child received 10 hr of speech intervention divided over 2 weeks. Perceptual and psychosocial outcome measures were used to determine intervention effects.

RESULTS

Children who received linguistic-phonological intervention to eliminate anterior oral CSCs had significantly higher correctly produced consonant scores and health-related quality of life (HRQoL) scores compared to children who received motor-phonetic intervention to eliminate anterior oral CSCs. In the group of children who received intervention to eliminate non-oral CSCs, no significant differences were found in the correctly produced consonant scores nor in the HRQoL scores between the two intervention approaches.

CONCLUSIONS

Linguistic-phonological intervention seems to be more appropriate to eliminate anterior oral CSCs. The beneficial effects of linguistic-phonological intervention were less pronounced in children with non-oral CSCs. Perhaps, children with non-oral CSCs benefit more from a hybrid phonetic-phonological approach. This study is a step forward in the provision of performance-specific intervention in children with a CP ± L. Replication in larger samples is needed and will aid to tailor treatment plans to the needs of our patients.

Canonical babbling ratio - Concurrent and predictive evaluation of the 0.15 criterion

INTRODUCTION

Canonical babbling ratio (CBR) is a commonly used measure to quantify canonical babbling (CB), and 0.15 is the commonly accepted criterion for the canonical babbling stage. However, this has not been thoroughly investigated. The aim of this study was to evaluate the validity of this criterion using concurrent and predictive comparisons.

METHODS

Longitudinal data from 50 children recruited in different clinical projects were used. At 10 months of age, CBR was calculated based on counted utterances from audio-video recorded parent-child interactions. The videos were also assessed by CB observation, where an observer made an overall judgement on whether the child was in the canonical babbling stage or not. For the concurrent evaluation, CBR was compared to CB observation as a reference test, using area under the curve (AUC). The criterion resulting in the best combination of sensitivity and specificity was identified using positive likelihood ratios. In the predictive comparisons CBR was analyzed as a predictor of speech/language difficulties at 30-36 months. Participants presenting with difficulties in consonant production and/or parent-reported vocabulary were considered to have speech/language difficulties. Sensitivity and specificity were compared for CBR using the 0.15 criterion and the new criterion identified in this study.

RESULTS

An AUC of 0.87 indicated that CBR is a valid measure of canonical babbling in 10-month-old children. The best combination of sensitivity and specificity was found at a criterion of 0.14 (sensitivity 0.96, specificity 0.70). In the predictive comparison, CBR with a 0.14 or 0.15 criterion revealed the same sensitivity (0.71) but 0.14 showed a slightly better specificity (0.52 versus 0.42).

CONCLUSIONS

CBR is a valid measure of CB (at 10 months). However, when using CBR to classify children's babbling as canonical or non-canonical, researchers need to carefully consider the implications of the chosen criterion.

Early Communication Behaviors in Infants With Cleft Palate With and Without Robin Sequence: A Preliminary Study

OBJECTIVE

To investigate the early communication behaviors in infants with nonsyndromic isolated cleft palate (iCP) and Robin sequence (RS).

DESIGN

Group comparison using parent report.

PARTICIPANTS

There were 106 participants included in this study. Two groups were selected from the UK Cleft Collective resource. Parents had completed the Language ENvironment Analysis Developmental Snapshot questionnaire when their child turned 13 months. There were 78 participants in the iCP group and 28 in the RS group.

MAIN OUTCOME MEASURE(S)

Total number of communication behaviors reported on the questionnaire. Subdomains for expressive and receptive language and social communication behaviors were also analyzed.

RESULTS

There were no statistically significant group differences. Parents of infants with RS reported fewer later communication behaviors compared to the iCP group. Infants in both groups had fewer communication behaviors compared to the normative sample. Across the whole sample, post hoc analysis revealed a significant correlation between severity of the cleft and social communication behaviors and expressive but not receptive language. Infants with a cleft of the hard and soft palate were more likely to be in the RS group (odds ratio: 7.04 [95% CI: 1.55-32.04]; P = .01).

CONCLUSIONS

Both groups reported similar levels of early communication. Some divergence of more complex language skills was seen, although there were no significant group differences. A relationship with the diagnosis of a cleft of the hard or soft palate with expressive language behaviors was found. Further study into the impact of cleft severity on early speech development and the relationship with later language skills is needed along with longitudinal follow-up of this population.

Speech and Audiology Outcomes After Single-Stage Versus Early 2-Stage Cleft Palate Repair

PURPOSE

The timing and management of patients with cleft palates have been controversial. Early soft palate closure at the time of cleft lip repair followed by hard palate closure at a second stage has been hypothesized to improve speech and audiology outcomes. This study compares cleft palate patients who have undergone single-stage versus 2-stage cleft palate repairs and the outcomes on speech and hearing.

METHODS

A retrospective chart review identified patients with diagnosis of cleft lip with complete cleft palate who underwent either single or 2-stage repair from 2006 to 2012. Data collected included age at each surgery, necessity of further speech surgery for velopharyngeal insufficiency, frequency of tympanostomy tube placement, presence of hearing loss, and speech assessment data graded per the validated Americleft speech scale.

RESULTS

A total of 84 patients were identified and subdivided into groups of single-stage and 2-stage repair. The mean age at the time of single-stage palate repair was 13.3 months. For the 2-stage group, the mean ages were 4.2 and 11.8 months for the soft palate and hard palate repairs, respectively. Comparing the single-stage versus 2-stage palate repairs, there was no significant difference in all speech parameters including hypernasality, hyponasality, nasal air emission, articulation, expressive language, receptive language, speech intelligibility, and speech acceptability for both unilateral and bilateral cleft lip/palate patients. Two-stage repair was associated with increased number of tympanostomy tube placement compared with single-stage repair (relative risk, 1.74; P = 0.009), and the first set of tubes was performed at a statistically significantly younger age, 4.5 months in the 2-stage repair compared with 16.9 months in the single-stage (P = 0.012) with 87.5% performed with first stage of repair. However, there was no difference in the types, degrees of hearing loss, or the presence of at least mild conductive hearing loss at latest follow-up audiograms between the groups.

CONCLUSIONS

There was no significant benefit with respect to speech or hearing outcomes between single-stage and 2-stage cleft palate repairs. This advocates for surgeon and family preference in the timing of cleft palate repair.

Persistence, strength, isolation, and trauma: An ethnographic exploration of raising children with cleft palate

BACKGROUND

The lives of families of young children with cleft palate (±lip) are complex. Multiple interventions are required as part of the long-term multidisciplinary treatment for children with CP±L, with an impairment-focused approach prevailing. Research with young children with CP±L has focused on treatment and intervention, and previous qualitative research has been collected predominantly via interviews, so little is understood about the day-to-day lives of families of young children with CP±L.

AIMS

(1) To increase understanding of the lives of children with CP±L and their families by applying an ethnographic lens to improve clinical practice (2) to identify key interactions and encounters that shape the experiences of children with CP±L and their families (3) to examine how family-centered practice can enhance practitioner-family relationships in providing effective and evidence-based care for children with CP±L.

METHOD

Ethnographic observations of seven families of children with CP±L and their families and educators including parents, siblings, aunts, grandparents, and teachers involved multiple site visits. Rich data were collected to gather information about different aspects of their lives (such as their strengths, routines, preferences, challenges and experiences). There were 84 artefacts collected: 18 interviews, 29 videos, one extended audio recording of a mealtime, seven photos contributed by families, seven case history questionnaires, and 22 field notes. These data were analyzed inductively using thematic analysis.

RESULTS

Three overarching themes and 11 subthemes were identified: (1) the whole child (persistence, communication, activities, mealtimes), (2) family strength and support (strong families, external support, attitudes, advocacy, positive medical experiences) and (3) family isolation and trauma (negative medical experiences, traumatic and challenging experiences).

CONCLUSION

This is the first study to use ethnographic methodology to facilitate the collection of unique insights into the lives of young children with CP±L and their families to improve clinical practice for SLPs. The unique application of family-centered practice with these families promoted trust and highlighted their challenges and strengths which could be considered by SLPs to provide holistic intervention.

The Effect of Surgical Timing on 30-Day Outcomes in Cleft Palate Repair

BACKGROUND

The optimal age for cleft palate repair continues to be debated, with little discussion of surgical risk related to operative timing. This study of 3088 cleft palate patients analyzed the impact of surgical timing on perioperative and 30-day postoperative outcomes.

METHODS

Primary cleft palate repairs were identified in the National Surgical Quality Improvement Program database from 2012 to 2015. Data were combed for total postoperative complications, rates of readmission and reoperation, operating room time, and length of stay. Bivariate analyses were performed comparing 3-month periods from months 6 to 18, and months 0 to 5, 18 to 23, 24 to 29, and 30 to 59.

RESULTS

Despite a higher proportion of isolated soft palate closure, children operated on before 6 months had a higher complication rate than children at other ages (7.1 percent versus 3.2 percent; OR, 2.4; p = 0.04), and higher rates of both readmission (3.6 percent versus 1.4 percent; OR, 3.6; p = 0.02) and reoperation (2.4 percent versus 0.5 percent; OR, 4.7; p = 0.04). There were no differences in short-term outcomes for any other age group younger than 5 years, and no differences in hospital length of stay among any age groups.

CONCLUSIONS

The authors' findings suggest a relative contraindication to operation before 6 months. As there were no differences between any other age groups, long-term speech optimization should continue to be the primary consideration for operative planning. These findings improve the current rationale for palatoplasty timing, and can aid surgeons and parents in the surgical decision-making process.

CLINICAL QUESTION/LEVEL OF EVIDENCE

Therapeutic, III.

Adding a fourth rater to three had little impact in pre-linguistic outcome classification

The consequence of differing levels of agreement across raters is rarely studied. Subsequently, knowledge is limited on how number of raters affects the outcome. The present study aimed to examine the impact on pre-linguistic outcome classifications of 12-month-old infants when using four raters compared to three. Thirty experienced Speech and Language Therapists (SLTs) from five countries assessed 20 minute video recordings of four 12-month-old infants during a play session with a parent. One recording was assessed twice. A naturalistic listening method in real time was used. This involved: (1) assessing, each syllable as canonical or non-canonical, and (2) following the recording, assessing if the infant was babbling canonically and listing the syllables the infant produced with command. The impact that four raters had on outcome, compared to three, was explored by classifying the outcome based on all possible combinations of three raters and determining the frequency that the outcome assessment changed when a fourth assessor was added. Results revealed that adding a fourth rater had a minimal impact on canonical babbling ratio assessment. Presence/absence of canonical babbling and size of consonant inventory showed a negligible impact on three out of four recordings, whereas the size of syllable inventory and presence/absence of canonical babbling was minimally affected in one recording by adding a fourth rater. In conclusion, adding a forth rater in assessment of pre-linguistic utterances in 12-month-old infants with naturalistic assessment in real time does not affect outcome classifications considerably. Thus, using three raters, as opposed to four, is recommended.

Perceptual Speech Outcomes After Early Primary Palatal Repair in Ugandan Patients With Cleft Palate

OBJECTIVE

To provide speech outcomes of English-speaking Ugandan patients with a cleft palate with or without cleft lip (CP±L).

DESIGN

Prospective case-control study.

SETTING

Referral hospital for patients with cleft lip and palate in Uganda.

PARTICIPANTS

Twenty-four English-speaking Ugandan children with a CP±L (15 boys, 9 girls, mean 8.4 years) who received palatal closure prior to 6 months of age and an age- and gender-matched control group of Ugandan children without cleft palate.

INTERVENTIONS

Comparison of speech outcomes of the patient and control group.

MAIN OUTCOME MEASURES

Perceptual speech outcomes including articulation, resonance, speech understandability and acceptability, and velopharyngeal composite score (VPC-sum). Information regarding speech therapy, fistula rate, and secondary surgery.

RESULTS

Normal speech understandability was observed in 42% of the patients, and 38% were judged with normal speech acceptability. Only 16% showed compensatory articulation. Acceptable resonance was found in 71%, and 75% of the patients were judged perceptually to present with competent velopharyngeal function based on the VPC-sum. Additional speech intervention was recommended in 25% of the patients. Statistically significant differences for all these variables were still observed with the control children (P < .05).

CONCLUSIONS

Overall, acceptable speech outcomes were found after early primary palatal closure. Comparable or even better results were found in comparison with international benchmarks, especially regarding the presence of compensatory articulation. Whether this approach is transferable to Western countries is the subject for further research.

Canonical Babbling and Early Consonant Development Related to Hearing in Children With Otitis Media With Effusion With or Without Cleft Palate

OBJECTIVE

To investigate and compare babbling, early consonant production and proficiency from 10 to 36 months of age and its relationship with hearing in children with otitis media with effusion (OME) with or without cleft palate.

DESIGN

Prospective, longitudinal group comparison study.

SETTING

University hospital.

PARTICIPANTS

Fifteen children born with nonsyndromic cleft palate with or without cleft lip (CP±L) and 15 age-matched children with hearing loss (HL) associated with OME but without cleft palate (noncleft group).

MAIN OUTCOME MEASURES

Canonical babbling (CB) and early consonant variables (presence of oral stops, anterior stops, dental/alveolar stops, number of different true consonants) at 10 and 18 months, and percentage of consonants correct proficiency (PCC) at 36 months.

RESULTS

A total of 54% of the CP±L group and 77% of the noncleft group had CB. The noncleft group had a significantly higher prevalence of all consonant variables. Percentage of consonants correct was 61.9% in the CP±L group and 81.6% in the noncleft group. All early consonant variables except CB were significantly related to PCC. Hearing sensitivity at 18 and 30 months correlated with PCC and explained 40% of the variation.

CONCLUSIONS

Mild HL impacted presence of CB at 10 months and was related to consonant proficiency at 36 months in children with HL associated with OME and children with cleft palate. The noncleft group showed results at 36 months similar to children with normal hearing; however, the CP±L group did not. Although the cleft palate may have a bigger impact on the speech development, management of hearing sensitivity would also be beneficial.

Holistic Communication Assessment for Young Children With Cleft Palate Using the International Classification of Functioning, Disability and Health:Children and Youth

Purpose Children with a cleft palate (± cleft lip; CP±L) can have difficulties communicating and participating in daily life, yet speech-language pathologists typically focus on speech production during routine assessments. The International Classification of Functioning, Disability and Health: Children and Youth Version (ICF-CY; World Health Organization, 2007) provides a framework for holistic assessment. This tutorial describes holistic assessment of children with CP±L illustrated by data collected from a nonclinical sample of seven 2- to 3-year-old children, 13 parents, and 12 significant others (e.g., educators and grandparents). Method Data were collected during visits to participants' homes and early childhood education and care centers. Assessment tools applicable to domains of the ICF-CY were used to collect and analyze data. Child participants' Body Functions including speech, language, and cognitive development were assessed using screening and standardized assessments. Participants' Body Structures were assessed via oral motor examination, case history questionnaires, and observation. Participants' Activities and Participation as well as Environmental and Personal Factors were examined through case history questionnaires, interviews with significant others, parent report measures, and observations. Results Valuable insights can be gained from undertaking holistic speech-language pathology assessments with children with CP±L. Using multiple tools allowed for triangulation of data and privileging different viewpoints, to better understand the children and their contexts. Several children demonstrated speech error patterns outside of what are considered cleft speech characteristics, which underscores the importance of a broader assessment. Conclusion Speech-language pathologists can consider incorporating evaluation of all components and contextual factors of the ICF-CY when assessing and working with young children with CP±L to inform intervention and management practices.

Assessment of prelinguistic vocalizations in real time: a comparison with phonetic transcription and assessment of inter-coder-reliability

This study investigated reliability of naturalistic listening in real time (NLRT) compared to phonetic transcription. Speech pathology students with brief training in NLRT assessed prelinguistic syllable inventory size and specific syllable types in typically developing infants. A second study also examined inter-coder reliability for canonical babbling, canonical babbling ratio and presence of oral stops in syllable inventory of infants with cleft palate, by means of NLRT. In study 1, ten students independently assessed prelinguistic samples of five 12-month-old typically developing infants using NLRT and phonetic transcription. Coders assessed syllable inventory size as more than twice as large using phonetic transcription as NLRT. Results showed a strong correlation between NLRT and phonetic transcription (syllables with more than five occurrences) for syllable inventory size (r = .60; p < .001). The methods showed similar results for inter-coder reliability of specific syllable types. In study 2, three other students assessed prelinguistic samples of twenty-eight 12-month-old infants with cleft palate by means of NLRT. Results revealed perfect inter-coder agreement for presence/absence of canonical babbling, strong correlations between the three coders' assessment of syllable inventory size (average r = .83; p < .001), but more inter-coder variability for agreement of specific syllable types. In conclusion, NLRT is a reliable method for assessing prelinguistic measures in infants with and without cleft palate with inter-coder agreement levels comparable to phonetic transcription for specific syllable types.

Benchmarking Speech, Velopharyngeal Function Outcomes and Surgical Characteristics Following the Sommerlad Protocol and Palate Repair Technique

Objective:

To report speech and velopharyngeal function (VPF) outcomes, and surgical characteristics, at age 5 following early complete palate closure using the Sommerlad protocol.

Design:

A retrospective, descriptive, cross-sectional consecutive series.

Setting:

A regional twin site center; a district general hospital and tertiary children’s hospital.

Participants:

Between 1993 and 2006, 877 participants underwent surgery; 712 (81%) were eligible for inclusion; 391 (55%) were included, 321 (45%) excluded. Thirteen percent had bilateral cleft lip and palate (CLP), 40% unilateral CLP, and 47% isolated cleft palate.

Intervention:

Lip and vomerine flap repair at 3 months of age (BCLP, UCLP) with soft palate closure using radical muscle dissection and retropositioning at a mean age of 6.6 months, range 4 to 23 months, as described and undertaken by Sommerlad.

Outcome Measures:

Velopharyngeal Composite (VPC) CAPS-A and articulation summary scores derived from analysis using the Cleft Audit Protocol for Speech-Augmented.

Results:

A VPC-SUM CAPS-A score of “0” was found in 97% reflecting adequate VPF; 73% had no cleft articulation difficulties. The BCLP group had the poorest articulation. Secondary speech surgery rate was 2.6% and 10.7% had fistula repair. Levator muscle quality and degree of retropositioning was associated with speech outcomes related to VPF. 2.6% had current features of VPI.

Conclusions:

Complete palate closure by around 6 months of age by the surgeon who described the technique led to excellent perceived VPF and very good speech outcomes at age 5, with less speech therapy and secondary speech surgery than commonly reported. These findings serve as a benchmark for the Sommerlad protocol and technique.

Longitudinal study of the development of obstruent correctness from ages 3 to 5 years in 108 Danish children with unilateral cleft lip and palate: a sub-study within a multicentre randomized controlled trial

BACKGROUND

Speech-sound development in preschoolers with unilateral cleft lip and palate (UCLP) as a group is delayed/disordered, and obstruents comprise the most vulnerable sound class.

AIMS

To evaluate the development of obstruent correctness (PCC-obs) and error types (cleft speech characteristics (CSCs) and developmental speech characteristics (DSCs)) from ages 3-5 and to investigate possible predictors (error types, velopharyngeal dysfunction (VPD) and gender) of PCC-obs at age 5 in two groups of children with UCLP.

METHODS & PROCEDURES

Subgroup analysis was conducted within a multicentre randomized controlled trial (RCT) of primary surgery (Scandcleft Project). A total of 125 Danish children with UCLP received lip and soft palate repair around 4 months of age and early hard palate closure at 12 months (EHPC group) or late hard palate closure at 36 months (LHPC group). Audio and video recordings of a naming test were available for 108 children at ages 3 and 5, and recordings were transcribed phonetically by blinded raters.

OUTCOMES & RESULTS

PCC-obs scores increased significantly from ages 3-5 in both groups, but with small effect sizes in the EHPC group that had higher scores at age 3 than the LHPC group. DSCs decreased in both groups whereas CSCs only decreased in the LHPC group that had more CSCs at age 3 than the EHPC group. The frequency of CSCs at age 3 was a significant predictor of PCC-obs scores at age 5 in both groups. DSCs significantly improved the logistic regression model in the EHPC group, whereas VPD and gender did not significantly improve the model in either group.

CONCLUSIONS & IMPLICATIONS

Although PCC-obs developed significantly from ages 3 to 5, children with UCLP as a group did not catch up to typically developing Danish children at age 5. Furthermore, the LHPC group at age 5 did not reach the 3-year level of the EHPC group, which means that delaying hard palate closure until age 3 is detrimental to obstruent development. Both CSCs and DSCs at age 3 were important predictors of PCC-obs at age 5 and should be considered when determining need for intervention.

Opinions of Speech-Language Pathologists Regarding Speech Management for Children With Cleft Lip and Palate

Objective:

The purpose of the present study was to examine practice patterns and opinions that speech-language pathologists (SLPs) have about speech-language intervention for children with cleft lip and palate.

Methods:

One hundred seven speech-language pathology members of the American Speech-Language-Hearing Association Special Interest Group 5: Craniofacial and Velopharyngeal Disorders Special Interest Group completed a 37-item online survey that examined common practices in early intervention as well as opinions about speech characteristics, assessment, and management strategies for children with cleft lip and palate.

Results:

The overwhelming majority of respondents (96%) agreed that speech-language pathologists (SLPs) should meet with parents before palatal surgery to discuss speech-language issues. Although 90% of the SLPs identified increasing consonant inventory as an early intervention goal, lack of consensus was evident regarding the type of consonant to stimulate. Respondents agreed that while blowing activities are not useful in strengthening labial, lingual, or velopharyngeal movements, they are useful in heightening awareness of oral airflow for children with cleft palate. A large degree of variability was evident in opinions regarding prevalence and treatment of compensatory articulations as well as the effectiveness of treatment strategies designed to reduce perceived hypernasality and audible nasal emission.

Conclusions:

The findings of this study indicate a large degree of variability in opinions of SLP respondents regarding assessment and treatment of children with cleft lip and palate.

The Implications of Nasal Substitutions in the Early Phonology of Toddlers With Repaired Cleft Palate

OBJECTIVE

To examine the implications of nasal substitutions in the early words of toddlers with cleft palate.

DESIGN

Retrospective.

PATIENTS

Thirty-four toddlers with nonsyndromic cleft palate and 20 noncleft toddlers, followed from ages 13 to 39 months.

MAIN OUTCOME MEASURES

The groups were compared for the percentage of toddlers who produced nasal substitutions in their early words. The percentage of toddlers with repaired cleft palate who produced nasal substitutions and were later suspected of having velopharyngeal dysfunction (VPD) was also examined.

RESULTS

Seventy-six percent of the toddlers in the cleft group (n = 26) and 35% of toddlers in the noncleft group (n = 7) produced nasal substitutions on one or more of their early words. Only 38% (10/26) of the toddlers with cleft palate who produced nasal substitutions in their early words were later diagnosed as having moderate-severe hypernasality and suspected VPD.

CONCLUSIONS

The presence of nasal substitutions following palatal surgery was not always an early sign of VPD. These substitutions were present in the early lexicon of children with and without cleft palate.

Influence of timing of delayed hard palate closure on articulation skills in 3-year-old Danish children with unilateral cleft lip and palate

BACKGROUND

Differing results regarding articulation skills in young children with cleft palate (CP) have been reported and often interpreted as a consequence of different surgical protocols.

AIMS

To assess the influence of different timing of hard palate closure in a two-stage procedure on articulation skills in 3-year-olds born with unilateral cleft lip and palate (UCLP). Secondary aims were to compare results with peers without CP, and to investigate if there are gender differences in articulation skills. Furthermore, burden of treatment was to be estimated in terms of secondary surgery, hearing and speech therapy.

METHODS & PROCEDURES

A randomized controlled trial (RCT). Early hard palate closure (EHPC) at 12 months versus late hard palate closure (LHPC) at 36 months in a two-stage procedure was tested in a cohort of 126 Danish-speaking children born with non-syndromic UCLP. All participants had the lip and soft palate closed around 4 months of age. Audio and video recordings of a naming test were available from 113 children (32 girls and 81 boys) and were transcribed phonetically. Recordings were obtained prior to hard palate closure in the LHPC group. The main outcome measures were percentage consonants correct adjusted (PCC-A) and consonant errors from blinded assessments. Results from 36 Danish-speaking children without CP obtained previously by Willadsen in 2012 were used for comparison.

OUTCOMES & RESULTS

Children with EHPC produced significantly more target consonants correctly (83%) than children with LHPC (48%; p < .001). In addition, children with LHPC produced significantly more active cleft speech characteristics than children with EHPC (p < .001). Boys achieved significantly lower PCC-A scores than girls (p = .04) and produced significantly more consonant errors than girls (p = .02). No significant differences were found between groups regarding burden of treatment. The control group performed significantly better than the EHPC and LHPC groups on all compared variables.

Speech outcome in young children born with unilateral cleft lip and palate treated with one- or two-stage palatal repair and the impact of early intervention

OBJECTIVES

The aim of this study was to describe speech at 1, 1;6 and 3 years of age in children born with unilateral cleft lip and palate (UCLP) and relate the findings to operation method and amount of early intervention received.

METHODS

A prospective trial of children born with UCLP operated with a one-stage (OS) palatal repair at 12 months or a two-stage repair (TS) with soft palate closure at 3-4 months and hard palate closure at 12 months was undertaken (Scandcleft). At 1 and 1;6 years the place and manner of articulation and number of different consonants produced in babbling were reported in 33 children. At three years of age percentage consonants correct adjusted for age (PCC-A) and cleft speech errors were assessed in 26 of the 33 children. Early intervention was not provided as part of the trial but according to the clinical routine and was extracted from patient records.

RESULTS

At age 3, the mean PCC-A was 68% and 46% of the children produced articulation errors with no significant difference between the two groups. At one year there was a significantly higher occurrence of oral stops and anterior place consonants in the TS group. There were significant correlations between the consonant production between one and three years of age, but not with amount of early intervention received.

CONCLUSIONS

The TS method was beneficial for consonant production at age 1, but not shown at 1;6 or 3 years. Behaviourally based early intervention still needs to be evaluated.

Profiles of vocal development in Korean children with and without cleft palate

This study longitudinally investigated vocal development in Korean children from 9 to 18 months of age with and without cleft palate (CP). Utterance samples were collected from 24 children with and without CP at 9, 12, 15 and 18 months of age. Each utterance was categorised into levels of vocalisation using the Korean-translated version of the Stark Assessment of Early Vocal Development-Revised (SAEVD-R). The results showed children with CP produced a significantly higher rate of precanonical vocalisations (the combination of Levels 1, 2, and 3) and a lower rate of Level 4 and 5 vocalisations than children without CP. Both groups showed decreases in Levels 1 and 2 and increases in Level 5 from 9 to 18 months of age. A significant increase in the proportion of Level 4 vocalisations across age was observed only in children without CP. Young Korean children with CP showed lower proportions of advanced vocalisation levels characterised by canonical and complex syllable structures across 9 and 18 months of age compared to children without CP.

Babbling in children with neurodevelopmental disability and validity of a simplified way of measuring canonical babbling ratio

Babbling is an important precursor to speech, but has not yet been thoroughly investigated in children with neurodevelopmental disabilities. Canonical babbling ratio (CBR) is a commonly used but time-consuming measure for quantifying babbling. The aim of this study was twofold: to validate a simplified version of the CBR (CBR^UTTER), and to use this measure to determine if early precursors to speech and language development could be detected in children with different neurodevelopmental disabilities. Two different data sets were used. In Part I, CBR^UTTER was compared to two other CBR measures using previously obtained phonetic transcriptions of 3571 utterances from 38 audio recordings of 12-18 month old children with and without cleft palate. In CBR^UTTER, number of canonical utterances was divided by total number of utterances. In CBR^syl, number of canonical syllables was divided by total number of syllables. In CBR^utt, number of canonical syllables was divided by total number of utterances. High agreement was seen between CBR^UTTER and CBR^syl, suggesting CBR^UTTER as an alternative. In Part II, babbling in children with neurodevelopmental disability was examined. Eighteen children aged 12-22 months with Down syndrome, cerebral palsy or developmental delay were audio-video recorded during interaction with a parent. Recordings were analysed by observation of babbling, consonant production, calculation of CBR^UTTER, and compared to data from controls. The study group showed significantly lower occurrence of all variables, except for of plosives. The long-term relevance of the findings for the speech and language development of the children needs to be investigated.

Development and validation of a screening procedure to identify speech-language delay in toddlers with cleft palate

The purpose of this study was to develop and validate a clinically useful speech-language screening procedure for young children with cleft palate ± cleft lip (CP) to identify those in need of speech-language intervention. Twenty-two children with CP were assigned to a +/- need for intervention conditions based on assessment of consonant inventory using a real-time listening procedure in combination with parent-reported expressive vocabulary. These measures allowed evaluation of early speech-language skills found to correlate significantly with later speech-language performance in longitudinal studies of children with CP. The external validity of this screening procedure was evaluated by comparing the +/- need for intervention assignment determined by the screening procedure to experienced speech-language pathologist (SLP)s' clinical judgement of whether or not a child needed early intervention. The results of real-time listening assessment showed good-excellent inter-rater agreement on different consonant inventory measures. Furthermore, there was almost perfect agreement between the children selected for intervention with the screening procedure and the clinical judgement of experienced SLPs indicate that the screening procedure is a valid way of identifying children with CP who need early intervention.

Variation among cleft centres in the use of secondary surgery for children with cleft palate: a retrospective cohort study

OBJECTIVES

To test whether cleft centres vary in their use of secondary cleft palate surgery, also known as revision palate surgery, and if so to identify modifiable hospital- and surgeon-factors that are associated with use of secondary surgery.

DESIGN

Retrospective cohort study.

SETTING

Forty-three paediatric hospitals across the United States.

PATIENTS

Children with cleft lip and palate who underwent primary cleft palate repair from 1999 to 2013.

MAIN OUTCOME MEASURES

Time from primary cleft palate repair to secondary palate surgery.

RESULTS

We identified 4,939 children who underwent primary cleft palate repair. At ten years after primary palate repair, 44% of children had undergone secondary palate surgery. Significant variation existed among hospitals (p<0.001); the proportion of children undergoing secondary surgery by 10 years ranged from 9% to 77% across hospitals. After adjusting for patient demographics, primary palate repair before nine months of age was associated with an increased hazard of secondary palate surgery (initial hazard ratio 6.74, 95% CI 5.30-8.73). Postoperative antibiotics, surgeon procedure volume, and hospital procedure volume were not associated with time to secondary surgery (p>0.05). Of the outcome variation attributable to hospitals and surgeons, between-hospital differences accounted for 59% (p<0.001), while between-surgeon differences accounted for 41% (p<0.001).

CONCLUSIONS

Substantial variation in the hazard of secondary palate surgery exists depending on a child's age at primary palate repair and the hospital and surgeon performing their repair. Performing primary palate repair before nine months of age substantially increases the hazard of secondary surgery. Further research is needed to identify other factors contributing to variation in palate surgery outcomes among hospitals and surgeons.

Effectiveness of a parent-implemented intervention program for young children with cleft palate

OBJECTIVE

This study investigated the effectiveness of a parent-implemented intervention on children's speech-language development and parents' interaction styles.

METHODS

Seventeen children with cleft palate (CP) and their mothers participated in all sessions of a parent-implemented intervention program. Nine children with CP and their mothers who did not receive the intervention were included to examine the full effectiveness of the program. The intervention program consisted of four phases, pre-intervention test, parent training, parent-implemented intervention at children's home for 3 months, and post-intervention test. Children's language and speech measures and maternal measures from pre- and post-intervention tests were compared between groups (intervention vs. no intervention).

RESULTS

Children who received a parent-implemented intervention exhibited significant improvement in language measures based on standardized tests and quantitative language and speech measures from spontaneous utterances. The children in the intervention group showed a significantly greater extent of change in expressive vocabulary size, number of total words, and mean length of utterance than did those who did not receive the intervention. Mothers who received the training showed a significantly decreased number of different words, increased responsiveness, and decreased non-contingent utterances for children's communication acts compared to those who did not receive the training.

CONCLUSIONS

The results of the study support the effectiveness of parent-implemented early intervention on positive changes in children's speech-language development and mothers' use of communication strategies.

Vowel bias in Danish word-learning: processing biases are language-specific

The present study explored whether the phonological bias favoring consonants found in French-learning infants and children when learning new words (Havy & Nazzi, 2009; Nazzi, 2005) is language-general, as proposed by Nespor, Peña and Mehler (2003), or varies across languages, perhaps as a function of the phonological or lexical properties of the language in acquisition. To do so, we used the interactive word-learning task set up by Havy and Nazzi (2009), teaching Danish-learning 20-month-olds pairs of phonetically similar words that contrasted either on one of their consonants or one of their vowels, by either one or two phonological features. Danish was chosen because it has more vowels than consonants, and is characterized by extensive consonant lenition. Both phenomena could disfavor a consonant bias. Evidence of word-learning was found only for vocalic information, irrespective of whether one or two phonological features were changed. The implication of these findings is that the phonological biases found in early lexical processing are not language-general but develop during language acquisition, depending on the phonological or lexical properties of the native language.

Observation is a valid way of assessing common variables in typical babbling and identifies infants who need further support

AIM

It is important to identify speech and language difficulties in children as early as possible. This study investigated the validity of observing babbling structure and consonant articulation.

METHODS

We focused on the language capabilities of children, with and without cleft palates, at 12 months of age (n = 29) and 18 months of age (n = 38), comparing observations made by speech and language pathologists on babbling structure and consonant articulation to audio recordings phonetically transcribed by experts blinded to the aim of the study. Descriptive cross-tabs, sensitivity, specificity and predictive values were analysed to investigate the validity of agreement between the methods.

RESULTS

We found high mean agreement between the two methods (94%) and within the observation (100%) and transcription (88.5%) teams when it came to canonical babbling, high-pressure/oral stop consonants and anterior placement of bilabial and dental/alveolar consonants. The observations had high specificity and negative predictive values (0.90-1) at both ages, with low to moderate sensitivity (0-0.86). However, there was low agreement, between and within the groups, on the number of consonant types and the unproven predictive variable glottal place of articulation.

CONCLUSION

Previously suggested predictive measures of babbling were shown to be valid and observation is a reliable method of identifying children who need further support.

Early Lexical Characteristics of Toddlers with Cleft Lip and Palate

Objective

To examine development of early expressive lexicons in toddlers with cleft palate to determine whether they differ from those of noncleft toddlers in terms of size and lexical selectivity.

Design

Retrospective.

Patients

A total of 37 toddlers with cleft palate and 22 noncleft toddlers.

Main Outcome Measures

The groups were compared for size of expressive lexicon reported on the MacArthur Communicative Development Inventory and the percentage of words beginning with obstruents and sonorants produced in a language sample. Differences between groups in the percentage of word initial consonants correct on the language sample were also examined.

Results

Although expressive vocabulary was comparable at 13 months of age for both groups, size of the lexicon for the cleft group was significantly smaller than that for the noncleft group at 21 and 27 months of age. Toddlers with cleft palate produced significantly more words beginning with sonorants and fewer words beginning with obstruents in their spontaneous speech samples. They were also less accurate when producing word initial obstruents compared with the noncleft group.

Conclusions

Toddlers with cleft palate demonstrate a slower rate of lexical development compared with their noncleft peers. The preference that toddlers with cleft palate demonstrate for words beginning with sonorants could suggest they are selecting words that begin with consonants that are easier for them to produce. An alternative explanation might be that because these children are less accurate in the production of obstruent consonants, listeners may not always identify obstruents when they occur.

Speech and Phonology in Swedish-Speaking 3-Year-Olds with Unilateral Complete Cleft Lip and Palate following Different Methods for Primary Palatal Surgery

Objective

To describe and compare speech and phonology at age 3 years in children born with unilateral complete cleft lip and palate treated with three different methods for primary palatal surgery.

Design

Prospective study.

Setting

Primary care university hospitals.

Participants

Twenty-eight Swedish-speaking children born with nonsyndromic unilateral complete cleft lip and palate.

Interventions

Three methods for primary palatal surgery: two-stage closure with soft palate closure between 3.4 and 6.4 months and hard palate closure at mean age 12.3 months (n = 9) or 36.2 months (n = 9) or one-stage closure at mean age 13.6 months (n = 10).

Main Outcome Measures

Based on independent judgments performed by two speech-language pathologists from standardized video recordings: percent correct consonants adjusted for age, percent active cleft speech characteristics, total number of phonological processes, number of different phonological processes, hypernasality, and audible nasal air leakage. The hard palate was unrepaired in nine of the children treated with two-stage closure.

Results

The group treated with one-stage closure showed significantly better results than the group with an unoperated hard palate regarding percent active cleft speech characteristics and total number of phonological processes.

Conclusions

Early primary palatal surgery in one or two stages did not result in any significant differences in speech production at age 3 years. However, children with an unoperated hard palate had significantly poorer speech and phonology than peers who had been treated with one-stage palatal closure at about 13 months of age.

Longitudinal comparison of early speech and language milestones in children with cleft palate: a comparison of US and Slovak children

The purpose of this study was to compare early speech and language development of children with and without cleft lip and/or palate (CLP) in the US and Slovakia from 6 to 24 months of age. Thirty-two children from the US (eight with CLP and eight noncleft) and Slovakia (eight with CLP and eight noncleft) participated in this study. The children were videotaped at four time points for 30 minutes during mother-child interaction with play sets controlled for early-developing sounds in each language. Mean Babbling Level, consonant inventories, number of different words and mean length of utterance were calculated for 6- to 24-month samples. Results indicated that the US and Slovak groups showed similar performance across the ages. Cleft and noncleft groups showed significant differences in acquisition of all of the speech and language measures. High-pressure consonants, particularly alveolar place of articulation, were problematic for children with CLP.

Lexical Selectivity in Danish Toddlers with Cleft Palate

Objective

To study if Danish children with cleft palate display lexical selectivity in their early lexicon at 18 months of age.

Design

A cross-sectional study.

Participants

Thirty-four children with unilateral cleft lip and palate and 35 children without cleft palate, matched for gender and age.

Methods

All participants were video recorded at 18 months of age during play interaction with a parent. The video recordings were transcribed according to the International Phonetic Alphabet and an individual consonant inventory was established for each participant. The video recordings were also analyzed with respect to word productions, establishing an observed productive vocabulary size for each participant.

Results

At 18 months of age Danish children with cleft palate showed marked lexical selectivity in their early words. The distribution of consonant classes observed at 11 months of age in a previous study of the children with cleft palate was almost perfectly reflected in their early lexicon at 18 months. The early lexicon of children with cleft palate differed from the early lexicon of their noncleft peers.

Conclusions and Implications

Danish toddlers with cleft palate display lexical selectivity in the early lexicon as it has been described for English-speaking toddlers with and without cleft palate, even though some qualitative differences were found.

Long-Term, Longitudinal Follow-Up of Individuals with Unilateral Cleft Lip and Palate after the Gothenburg Primary Early Veloplasty and Delayed Hard Palate Closure Protocol: Speech Outcome

Objective

To investigate long-term, longitudinal speech outcome in patients born with unilateral cleft lip and palate treated according to a two-stage primary palatal protocol with early veloplasty and delayed hard palate closure.

Design

Retrospective, longitudinal cohort study.

Setting

A university hospital in western Sweden.

Subjects

A consecutive series of 55 patients from the total cohort of 65 were included. All patients had surgical procedures at Sahlgrenska University Hospital, Gothenburg, Sweden.

Methods

Standardized audio recordings were blindly analyzed at 5, 7, 16, and 19 years of age and after at a clinical visit at 10 years of age. Typical cleft speech variables were rated independently on ordinal scales. Intelligibility and perceived velopharyngeal function were assessed also. Prevalences of speech characteristics were determined, and interrater and intrarater agreement were calculated.

Results

Prominent hypernasality, nasal air leakage, and retracted oral articulation at 5 years were markedly reduced throughout the years with low prevalences at ages 16 and 19 years. Perceived velopharyngeal competence was noted in 82% at age 16 and 87% at age 19 years along with normal intelligibility. Pharyngeal flap surgery was performed in 6 of the 55 patients (11%).

Conclusions

Long-term speech outcome in patients with two-stage palatoplasty with early soft palate repair was considered good and improved even before hard palate repair. The typical retracted oral articulation was quite frequent during the early ages; whereas, nonoral misarticulations were almost nonexistent, implying good velopharyngeal competence.

Influence of Timing of Hard Palate Repair in a Two-Stage Procedure on Early Speech Development in Danish Children with Cleft Palate

Objective

To investigate the influence of timing of hard palate closure on early speech development from 18 months to 3 years of age.

Design

A prospective, randomized clinical trial.

Participants

Thirty-four children with unilateral cleft lip and palate (UCLP) with velum closure at 4 months of age, and hard palate closure at 12 months (early hard palate repair, EarlyHPR) or 36 months (late hard palate unrepaired, LateHPU) by random assignment. Thirty-five control children were matched for gender and age.

Methods

All children were video recorded during a play interaction with a parent at 18 months of age. These recordings were transcribed according to the International Phonetic Alphabet. At 36 months a single word naming test was administered.

Results

At 18 months the LateHPU group produced fewer labial stops and more velar stops than the EarlyHPR group. Unlike the EarlyHPR group, the LateHPU group produced fewer vocalizations, consonants, and consonants permissible in word-initial position than the control group. Additionally, both cleft palate groups had a smaller productive vocabulary than the control group, but unlike the EarlyHPR group, the LateHPU group produced a smaller number of word tokens in social interaction than the control group. By 3 years of age, the LateHPU group had a (severely) restricted phonological system and produced more cleft speech characteristics than the EarlyHPR group.

Conclusions

Surgical timing of hard palate repair in a two-stage procedure appears to have an influence on early speech development in children with cleft palate.

Application of the International Classification of Functioning, Disability, and Health–Children and Youth Version (ICF-CY) to Cleft Lip and Palate

Objective

In recent health policy discussions, the World Health Organization has urged member states to implement the International Classification of Functioning, Disability, and Health: Children and Youth Version in their clinical practice and research. The purpose of this study was to identify codes from the International Classification of Functioning, Disability, and Health: Children and Youth Version relevant for use among children with cleft lip and/or palate, thereby highlighting the potential value of these codes for interprofessional cleft palate-craniofacial teams.

Design

The scope of recent published research in the area of cleft lip and/or palate was reviewed and compared with meaningful terms identified from the International Classification of Functioning, Disability, and Health: Children and Youth Version. In a five-step procedure, a consensus-based list of terms was developed that was linked separately to International Classification of Functioning, Disability, and Health: Children and Youth Version categories and codes. This provided a first draft of a core set for use in the cleft lip and/or palate field.

Conclusions

Adopting International Classification of Functioning, Disability, and Health: Children and Youth Version domains in cleft lip and/or palate may aid experts in identifying appropriate starting points for assessment, counseling, and therapy. When used as a clinical tool, it encourages health care professionals to go beyond treatment and outcome perspectives that are focused solely on the child and to include the children's environment and their familial/societal context. In order to establish improved, evidence-based interdisciplinary treatments for children with cleft lip and/or palate, more studies are needed that seek to identify all the influencing conditions of activities, children's participation, and barriers/facilitators in their environments.

An analysis of the frame-content theory in babble of 9-month-old babies with cleft lip and palate

The aim of this study was to examine the consonant-vowel co-occurrence patterns predicted by the Frame-Content theory in 16 nine-month-old babies with unrepaired cleft palate (±cleft lip) and 16 age-matched non-cleft babies. Babble from these babies was phonetically transcribed and grouped according to the intrasyllabic predictions of the theory (labial-central, alveolar-front, and velar-back). Both groups demonstrated the three consonant-vowel co-occurrence patterns predicted by the Frame-Content theory. Other patterns not predicted by the Frame-Content theory emerged as strong patterns as well.

LEARNING OUTCOMES

The reader will be able to: • Describe consonant-vowel co-occurrence patterns produced by babies with and without cleft palate. • Describe vowel inventories of babies with cleft palate. • Identify possible therapy targets for babies with cleft palate.

Early Consonant Production in Swedish Infants with and without Unilateral Cleft Lip and Palate and Two-Stage Palatal Repair

Objective

To investigate consonant production at 12 and 18 months of age following early soft palate repair in infants with unilateral cleft lip and palate (UCLP), and to compare it with typically developing children without clefts.

Design

Randomized study with comparison group.

Participants

Twenty Swedish infants born with UCLP and 21 without clefts (COMP) were included in a randomized trial of palatal surgery (Scandcleft project). Soft palate closure was completed at age 5 months; hard palate closure was performed in 11 of the infants with UCLP at 1 year of age (HPC) and was left open in nine (HPO).

Method

Audio recordings at 12 months (UCLP = 9, COMP = 21) and at 18 months (UCLP = 18, COMP = 21) were phonetically transcribed. Consonant inventory, frequency of manner and place of articulation, true canonical babbling (TCB), and impact of hearing status were analyzed.

Results

At 12 months of age, all children had reached the stage of TCB. Mild hearing impairment was significantly correlated with fewer consonant types. A lower frequency of dentals and oral stops was found in the UCLP group than in the COMP group. However, the number of oral stops was high compared with what has been previously reported.

Conclusions

Early soft palate closure seems to give a relatively high number of oral stops even with the hard palate unrepaired, although with significantly fewer dentals/alveolars than are seen in peers without clefts. Differences in consonant inventory were correlated with hearing function.

A Longitudinal Study of Speech Production in Swedish Children with Unilateral Cleft Lip and Palate and Two-stage Palatal Repair

Objective:

To describe speech production longitudinally in a group of children with unilateral cleft lip and palate (UCLP).

Participants:

Twenty consecutive children with UCLP and nine age-matched children without clefts in a comparison group.

Intervention:

A two-stage palatal repair procedure with soft palate closure at 6 months and hard palate repair at 3 to 4 years.

Main Outcome Measures:

Percent correct consonants (PCC), percent correct places (PCP), and percent correct manners (PCM) at 3, 5, and 7 years of age. Cleft speech errors at the same ages. Previously collected data on number of consonant tokens, consonant types, frequency of occurrence of places and manners of articulation at 18 months.

Results:

PCC and PCP were significantly lower in the UCLP group than in the comparison group at all ages. Number of consonant types and frequency of occurrence of dental plosives at 18 months correlated significantly with PCC at age 3. A high frequency of velar plosives at 18 months correlated significantly with a high prevalence of retracted oral articulation (dental/alveolar to palatal or velar) at both 3 and 5 years of age.

Conclusions:

The UCLP group performed worse than the comparison group at all ages. A high occurrence of dental plosives as well as a high number of consonant types in babbling and first words seem to be good indicators for better consonant production in later speech. The same prevalence of retracted oral articulation as in previous studies is attributed to the surgical technique.
