Universal Parameters for Reporting Speech Outcomes in Individuals with Cleft Palate

Children's Attitudes toward Peers with Unintelligible Speech Associated with Cleft Lip and/or Palate

Objective

The objective of this study was to investigate whether reduced speech intelligibility in children with cleft palate affects social and personal attribute judgments made by typically developing children of different ages.

Design

The study (1) measured the correlation between intelligibility scores of speech samples from children with cleft palate and social and personal attribute judgments made by typically developing children based on these samples and (2) compared the attitude judgments made by children of different ages.

Participants

A total of 90 typically developing children, 30 in each of three age groups (7 to 8 years, 9 to 10 years, and 11 to 12 years).

Outcome Measures

Speech intelligibility scores and typically developing children s attitudes were measured using eight social and personal attributes on a three-point rating scale.

Results

There was a significant correlation between the speech intelligibility scores and attitude judgments for a number of traits: “sick-healthy” as rated by the children aged 7 to 8 years, “no friends-friends” by the children aged 9 to 10 years, and “ugly-good looking” and “no friends-friends” by the children aged 11 to 12 years. Children aged 7 to 8 years gave significantly lower ratings for “mean-kind” but higher ratings for “shy-outgoing” when compared with the other two groups.

Conclusions

Typically developing children tended to make negative social and personal attribute judgments about children with cleft palate based solely on the intelligibility of their speech. Society, educators, and health professionals should work together to ensure that children with cleft palate are not stigmatized by their peers.

Audiovisual materials are effective for enhancing the correction of articulation disorders in children with cleft palate

INTRODUCTION

Children with cleft palate frequently show speech disorders known as compensatory articulation. Compensatory articulation requires a prolonged period of speech intervention that should include reinforcement at home. However, frequently relatives do not know how to work with their children at home.

OBJECTIVE

To study whether the use of audiovisual materials especially designed for complementing speech pathology treatment in children with compensatory articulation can be effective for stimulating articulation practice at home and consequently enhancing speech normalization in children with cleft palate.

MATERIALS AND METHODS

Eighty-two patients with compensatory articulation were studied. Patients were randomly divided into two groups. Both groups received speech pathology treatment aimed to correct articulation placement. In addition, patients from the active group received a set of audiovisual materials to be used at home. Parents were instructed about strategies and ideas about how to use the materials with their children. Severity of compensatory articulation was compared at the onset and at the end of the speech intervention.

RESULTS

After the speech therapy period, the group of patients using audiovisual materials at home demonstrated significantly greater improvement in articulation, as compared with the patients receiving speech pathology treatment on - site without audiovisual supporting materials.

CONCLUSION

The results of this study suggest that audiovisual materials especially designed for practicing adequate articulation placement at home can be effective for reinforcing and enhancing speech pathology treatment of patients with cleft palate and compensatory articulation.

Perceptual Judgments of Resonance, Nasal Airflow, Understandability, and Acceptability in Speakers with Cleft Palate: Ordinal versus Visual Analogue Scaling

Objective

To investigate the reliability of ordinal versus visual analogue scaling (VAS) ratings for perceptual judgments of nasal resonance, nasal airflow, understandability, and acceptability in speakers with cleft palate.

Design

Within-subjects comparative study.

Setting

Multisite.

Participants

Five specialist speech and language therapists from U.K. Regional Cleft Centres.

Outcome Measures

Participants rated 30 audio speech samples obtained from the Speech and Language Therapy archives of Great Ormond Street Hospital. They rated the identified speech parameters using each scaling method, with 1 month between rating tasks. The model of best fit was determined to examine validity, and both intra- and inter-rater reliability were also computed.

Results

VAS ratings were valid for all parameters when plotted against ordinal ratings, and the model of best fit revealed only a slightly stronger curvilinear than linear relationship between the scaling methods. Intra-rater reliability was high for both rating methods across all six speech parameters. There was also high inter-rater reliability for both ordinal and VAS ratings of hypernasality, nasal emission, nasal turbulence, understandability, and acceptability, and for the ordinal ratings of hyponasality.

Conclusions

Perceptual judgments of nasal resonance, nasal airflow, understandability, and acceptability were similar using VAS and ordinal scaling, indicating that both scaling methods were appropriate for measuring the cleft speech parameters. VAS, however, may offer statistical advantages, and there is a growing body of evidence advocating its use for the measurement of prothetic speech parameters.

Five-year speech and language outcomes in children with cleft lip-palate

OBJECTIVE

To investigate 5-year speech and language outcomes in children with cleft lip/palate (CLP).

MATERIALS AND METHODS

Thirty-eight children aged 4-7 years and 8 months were recruited for this study. Speech abilities including articulation, resonance, voice, and intelligibility were assessed based on Thai Universal Parameters of Speech Outcomes. Language ability was assessed by the Language Screening Test.

RESULTS

The findings revealed that children with clefts had speech and language delay, abnormal understandability, resonance abnormality, and voice disturbance; articulation defects that were 8.33 (1.75, 22.47), 50.00 (32.92, 67.08), 36.11 (20.82, 53.78), 30.56 (16.35, 48.11), and 94.44 (81.34, 99.32).

CONCLUSIONS

Articulation errors were the most common speech and language defects in children with clefts, followed by abnormal understandability, resonance abnormality, and voice disturbance. These results should be of critical concern. Protocol reviewing and early intervention programs are needed for improved speech outcomes.

Perceptual Assessment of Velopharyngeal Dysfunction by Otolaryngology Residents

OBJECTIVE

To assess the ability of otolaryngology residents to rate the hypernasal resonance of patients with velopharyngeal dysfunction. We hypothesize that experience (postgraduate year [PGY] level) and training will result in improved ratings of speech samples.

STUDY DESIGN

Prospective cohort study.

SETTING

Otolaryngology training programs at 2 academic medical centers.

SUBJECTS AND METHODS

Thirty otolaryngology residents (PGY 1-5) were enrolled in the study. All residents rated 30 speech samples at 2 separate times. Half the residents completed a training module between the rating exercises, with the other half serving as a control group. Percentage agreement with the expert rating of each speech sample and intrarater reliability were calculated for each resident. Analysis of covariance was used to model accuracy at session 2.

RESULTS

The median percentage agreement at session 1 was 53.3% for all residents. At the second session, the median scores were 53.3% for the control group and 60% for the training group, but this difference was not statistically significant. Intrarater reliability was moderate for both groups. Residents were more accurate in their ratings of normal and severely hypernasal speech. There was no correlation between rating accuracy and PGY level. Score at session 1 positively correlated with score at session 2.

CONCLUSION

Perceptual training of otolaryngology residents has the potential to improve their ratings of hypernasal speech. Length of time in residency may not be best predictor of perceptual skill. Training modalities incorporating practice with hypernasal speech samples could improve rater skills and should be studied more extensively.

Influência da amostra de fala na classificação perceptiva da hipernasalidade

RESUMO Objetivo Investigar a influência do tipo de amostra de fala, conversa espontânea ou repetição de sentenças, sobre o índice de concordância intra e interavaliadores obtido na classificação perceptiva da hipernasalidade. Métodos Foram selecionadas e editadas 120 amostras de fala gravadas em áudio (60 contendo trechos de conversa espontânea e 60 contendo repetição de sentenças) de indivíduos com fissura de palato±lábio reparada, de ambos os sexos, com idade entre 6 e 52 anos (média=21±10 anos). Três fonoaudiólogas experientes, utilizando seus critérios internos, classificaram a hipernasalidade em escala de 4 pontos: 1=ausente, 2=leve, 3=moderada e 4=grave, primeiramente na amostra de conversa espontânea e, 30 dias depois, na repetição de sentenças. Os índices de concordância intra e interavaliadores foram estabelecidos para ambos os tipos de amostra de fala e comparados entre si por meio do Teste Z com nível de significância de 5%. Resultados A comparação dos índices de concordância intra-avaliadores entre os dois tipos de amostra de fala mostrou aumento dos coeficientes obtidos na análise da repetição de sentenças em relação aos obtidos na conversa espontânea, já a comparação entre os índices de concordância interavaliadores não mostrou diferença significante entre as três avaliadoras para os dois tipos de amostras de fala. Conclusão A repetição de sentenças favoreceu a confiabilidade do julgamento perceptivo da hipernasalidade de um mesmo avaliador, visto que a concordância intra-avaliadores na análise desta amostra de fala foi maior. No entanto, o tipo de amostra de fala não influenciou a concordância entre diferentes avaliadores.

Implications of Untreated Cleft Palate in the Developing World: Adaptation of an Outcome Measure

OBJECTIVES

To identify the implications of living with untreated cleft palate and develop an outcome measure which reflects the broad impact of surgery but is sensitive to the physical impact, speech changes, and psychosocial implications of late intervention. Design, Participants, Setting: Focus groups and individual interviews were used to gather information on the implications of living with untreated cleft palate and the impact of subsequent surgery. Participants included 11 individuals attending a cleft department in India whose cleft had persisted into adolescence or adulthood, as well as 16 of their family members. The findings were used to assess whether the Therapy Outcome Measure (TOM) could capture the implications of untreated cleft palate and the impact of surgery beyond that of speech alone.

RESULTS

The findings indicated that the implications of living with untreated cleft palate revolved around difficulties with communication, reduced autonomy, and nasal regurgitation. These issues are encapsulated within the third and fourth domains of the TOM, but there is a need for an adapted version (TOM-clp) to use in the developing world, incorporating areas specific to cleft palate.

CONCLUSION

The TOM has potential as a global tool for measuring the broad impact, including the psychosocial benefit, from attending to untreated cleft palate.

The relationship between the Nasality Severity Index 2.0 and perceptual judgments of hypernasality

PURPOSE

The Nasality Severity Index 2.0 (NSI 2.0) forms a new, multiparametric approach in the identification of hypernasality. The present study aimed to investigate the correlation between the NSI 2.0 scores and the perceptual assessment of hypernasality.

METHOD

Speech samples of 35 patients, representing a range of nasality from normal to severely hypernasal, were rated by four expert speech-language pathologists using visual analogue scaling (VAS) judging the degree of hypernasality, audible nasal airflow (ANA) and speech intelligibility. Inter- and intra-listener reliability was verified using intraclass correlation coefficients. Correlations between NSI 2.0 scores and its parameters (i.e. nasalance score of an oral text and vowel /u/, voice low tone to high tone ratio of the vowel /i/) and the degree of hypernasality were determined using Pearson correlation coefficients. Multiple linear regression analysis was used to investigate the possible influence of ANA and speech intelligibility on the NSI 2.0 scores.

RESULTS

Overall good to excellent inter- and intra-listener reliability was found for the perceptual ratings. A moderate, but significant negative correlation between NSI 2.0 scores and perceived hypernasality (r=-0.64) was found, in which a more negative NSI 2.0 score indicates the presence of more severe hypernasality. No significant influence of ANA or intelligibility on the NSI 2.0 was observed based on the regression analysis.

CONCLUSION

Because the NSI 2.0 correlates significantly with perceived hypernasality, it provides an easy-to-interpret severity score of hypernasality which will facilitate the evaluation of therapy outcomes, communication to the patient and other clinicians, and decisions for treatment planning, based on a multiparametric approach. However, research is still necessary to further explore the instrumental correlates of perceived hypernasality.

LEARNING OUTCOMES

The reader will be able to (1) describe and discuss current issues and influencing variables regarding perceptual ratings of hypernasality; (2) describe and discuss the relationship between the Nasality Severity Index 2.0, a new multiparametric approach to hypernasality, and perceptual judgments of hypernasality based on visual analogue scale ratings; (3) compare these results with the correlations based on a single parameter approach and (4) describe and discuss the possible influence of audible nasal airflow and speech intelligibility on the NSI 2.0 scores.

Voice onset time of alveolar stop /t/ and realization of unaspirated affricates associated with Mandarin-speaking children with repaired cleft palate

PURPOSE

To examine perceptually the realization of unaspirated affricates and voice onset time (VOT) features of /t/ in Mandarin-speaking children with repaired cleft palate, and to explore the difficulties associated with unaspirated affricate production from the perspective of the VOT of /t/.

METHOD

Twenty-three children with repaired cleft palate and 22 age-matched typical native Mandarin speakers were recruited. Speakers with cleft palate were allocated into two groups based on expert perceptual judgment of nasality: one group with perceived normal resonance (PNR) (n = 14, average age = 9.3 years), and another group with perceived hypernasal resonance (PHR) (n = 9, average age = 10.3 years).

INTERVENTION

Stimuli were collected through a series of picture naming tasks, targeting the production of initial consonants /t/ and three unaspirated Mandarin affricates /ts, tʂ, tɕ/. The productions of each affricate were evaluated by two experienced speech therapists. The VOT of /t/ was measured using PRAAT speech analysis software.

RESULT

The majority of unaspirated affricates were omitted and/or weakly realized by the group of PHR speakers, but not for the PNR group. A significantly smaller mean VOT value associated with /t/ was identified for the PHR group, as compared to the PNR group. A group difference for VOT value was not found between the PNR group and the typical control group.

CONCLUSION

The voicing features of /t/ and omitted/weak realization of unaspirated affricates identified in the PHR group indicated that the deviant production of unaspirated affricates in the cleft palate group could be associated with the voicing characteristics of the alveolar stop /t/, and this merits further investigation.

Nasalância na presença e ausência da fricativa faríngea

RESUMO Objetivo: comparar os valores de nasalância em amostras de fala com e sem o uso de fricativa faríngea e, também, com e sem hipernasalidade. Métodos: um total de 840 amostras de fala foi analisado neste estudo. As amostras foram julgadas por três juízas experientes por consenso quanto aos aspectos hipernasalidade e fricativa faríngea. Os julgamentos foram distribuídos em quatro grupos: G1: 255 amostras de fala julgadas como representativas de hipernasalidade; G2: 130 amostras julgadas como representativas do uso de fricativa faríngea e hipernasalidade; G3: 280 amostras julgadas como representativas de fala normal em falantes com história de fissura labiopalatina; G4: 175 amostras julgadas como representativas de fala normal em falantes sem história de fissura labiopalatina. Para análise dos dados foi utilizando o teste Kruskal-Wallis e quando houve diferença estatisticamente significante foi aplicado o teste Dunn's para comparar os grupos aos pares. Resultados: os julgamentos aferidos por consenso pelas três juízas permitiram a identificação de amostras representativas do uso de fricativa faríngea e da presença e ausência de hipernasalidade. Foram estabelecidos valores de nasalância (média e desvio padrão) para cada grupo e observou-se que houve diferença estatisticamente significante entre os grupos com alteração de fala (G1 e G2) e aqueles sem alteração (G3 e G4). A diferença entre o grupo com hipernasalidade (G1) e o grupo com FF (G2) não foi significante. Conclusão: o uso de FF não influenciou significantemente os valores de nasalância para a amostra estudada.

Spectral Analysis of Hypernasality in Cleft Palate Children: A Pre-Post Surgery Comparison

INTRODUCTION

Change in resonance is the most commonly experienced speech problems in children diagnosed with cleft lip and palate. The degree of nasality during normal speech production is maintained by the changes in velopharyngeal port. These variations in speech signal are reported to be successfully captured using acoustical tools like spectral analysis.

AIM

The present study investigated to note voice low tone to high tone ratio (VLHR) values for phonation samples of individuals with cleft palate before and after surgery.

MATERIALS AND METHODS

Thirty children with congenital cleft of palate within 8 to 15 years of age participated in the study. Three trials of sustained vowels (/a/,/i/ and /u/) were recorded at their comfortable pitch and loudness level in a noise free room using a hand held dynamic microphone. Praat software that utilized Hillenbrand algorithm was used to extract the VLHR values for samples recorded before and after recovery from the surgery.

RESULTS

Statistical analysis revealed significant decrease in VLHR values after surgery in comparison to before the surgery. Analysis of Variance revealed statistical significant difference at 95% confidence level.

CONCLUSION

It is concluded that VLHR parameter could be used as an index to measure nasality and can be included in the routine tool assessment protocol.

Correlation of Vocal Intensity with Velopharyngeal Closing Mechanism in Individuals with and without Complaint of Velopharyngeal Dysfunction

Introduction Velopharyngeal sphincter is a portion of the muscle of the palatopharyngeal arch that is capable of separating the oral cavity from the nasal cavity. It has not been determined yet whether voice intensity has an influence on this capacity. Velopharyngeal sphincter closure is accomplished by elevating and retracting the soft palate at the same time as the nasopharyngeal walls are constricted. Objective This study aims to correlate voice intensity with velopharyngeal sphincter closure in individuals without velopharyngeal dysfunction and patients with cleft lip and palate. Methods We conducted a cross-sectional, comparative, and contemporary study. The sample consisted of 16 individuals in the control group and 16 individuals in the study group. Patients underwent instrumental assessment, which we subsequently analyzed using a computer program, and a brief medical history review. The mean age of the control group was 27.6 years, whereas the mean age of the case group was 15.6 years. Results Cases showed higher voice intensity in regular and weak fricative sentences when compared with controls. There was no agreement on the analysis of the instrumental assessment between the assessors and the computer program. Regardless of voice intensity, the computer program demonstrated a similar closure pattern. Conclusion The computer program showed similar closure pattern for the three levels of intensity. There was no agreement between the three assessors and the closure pattern determined by the computer program. There was no statistically significant correlation between voice intensity and degree of velopharyngeal sphincter closure.

The Americleft Speech Project: A Training and Reliability Study

OBJECTIVE

To describe the results of two reliability studies and to assess the effect of training on interrater reliability scores.

DESIGN

The first study (1) examined interrater and intrarater reliability scores (weighted and unweighted kappas) and (2) compared interrater reliability scores before and after training on the use of the Cleft Audit Protocol for Speech-Augmented (CAPS-A) with British English-speaking children. The second study examined interrater and intrarater reliability on a modified version of the CAPS-A (CAPS-A Americleft Modification) with American and Canadian English-speaking children. Finally, comparisons were made between the interrater and intrarater reliability scores obtained for Study 1 and Study 2.

PARTICIPANTS

The participants were speech-language pathologists from the Americleft Speech Project.

RESULTS

In Study 1, interrater reliability scores improved for 6 of the 13 parameters following training on the CAPS-A protocol. Comparison of the reliability results for the two studies indicated lower scores for Study 2 compared with Study 1. However, this appeared to be an artifact of the kappa statistic that occurred due to insufficient variability in the reliability samples for Study 2. When percent agreement scores were also calculated, the ratings appeared similar across Study 1 and Study 2.

CONCLUSION

The findings of this study suggested that improvements in interrater reliability could be obtained following a program of systematic training. However, improvements were not uniform across all parameters. Acceptable levels of reliability were achieved for those parameters most important for evaluation of velopharyngeal function.

Speech nasality and nasometry in cleft lip and palate

INTRODUCTION

Perceptual evaluation is considered the gold standard to evaluate speech nasality. Several procedures are used to collect and analyze perceptual data, which makes it susceptible to errors. Therefore, there has been an increasing desire to find methods that can improve the assessment.

OBJECTIVE

To describe and compare the results of speech nasality obtained by assessments of live speech, the Test of Hypernasality (THYPER), assessments of audio recorded speech, and nasometry.

METHODS

A retrospective study consisting of 331 patients with operated unilateral cleft lip and palate. Speech nasality was assessed by four methods of assessment: live perceptual judgement, THYPER, audio-recorded speech sample judgement by multiple judges, and nasometry. All data were collected from medical records of patients, with the exception of the speech sample recording assessment, which was carried out by multiple judges.

RESULTS

The results showed that the highest percentages of absence of hypernasality were obtained from judgements performed live and from the THYPER, with equal results between them (79%). Lower percentages were obtained from the recordings by judges (66%) and from nasometry (57%).

CONCLUSION

The best results among the four speech nasality evaluation methods were obtained for the ones performed live (live nasality judgement by a speech pathologist and THYPER).

Consonant accuracy in Mandarin-speaking children with repaired cleft palate

OBJECTIVE

To compare the consonant production of Chinese-speaking cleft palate children with perceived hypernasal resonance (PHR) after palatoplasty and those with perceived normal resonance (PNR), and to assess the possible influence of language on articulation.

SETTING

Two hospital cleft lip and palate centers in mainland China.

PARTICIPANTS

Thirty-one speakers were allocated into two groups based on perceptual judgment results of their resonance provided by three speech therapists: one group with PNR (n=20, average age=9.3 years), and another group with PHR (n=11, average age=8.3 years). All participants had no known hearing or cognitive deficits.

INTERVENTION

Articulation was evaluated using two Mandarin Chinese assessment tools, the Putonghua Segmental Phonology Test and the Deep Test for Cleft Palate Speakers in Putonghua. Speaker consonant accuracy was evaluated by two experienced speech therapists.

RESULTS

Compared to individuals with PNR, the PHR group exhibited more difficulties on production of unaspirated consonants, including/b/,/t/,/k/,/ts/,/tʂ/ and/tɕ/, than for aspirated consonants.

CONCLUSION

The distinctive feature of aspiration in Mandarin phonology brought a language specific pattern to consonant production among those speakers with PHR after primary palatal closure.

Julgamento perceptivo-auditivo das oclusivas velares associadas à fissura labiopalatina por juízes com e sem experiência

RESUMO: Objetivo: verificar: a) o grau de concordância de juízes no julgamento perceptivo-auditivo da produção de oclusivas velares, antes e depois da fonoterapia; b) a possível influência da composição fonética das amostras de fala nesta concordância e c) se os julgamentos obtidos por juízes com experiência diferem daqueles obtidos por juízes sem experiência, nas condições investigadas. Métodos: 60 amostras de fala de uma criança com fissura labiopalatina (30 previamente e 30 posteriormente a fonoterapia) e 30 amostras de fala de uma criança com fala típica (normal) foram julgadas por um grupo de 9 juízes. Três fonoaudiólogos estabeleceram os julgamentos consensuais "padrão ouro" para o estudo. Seis outros juízes julgaram as amostras: três considerados com experiência (fonoaudiólogos) e três sem experiência (alunos de graduação). As amostras de fala incluíram palavras constituídas pelas oclusivas velares /k/ e /g/ combinada com as vogais /a/, /i/ e /u/. Os juízes foram instruídos a julgar a presença, a ausência das oclusivas velares ou a presença de AC nestas amostras. Resultados: verificou-se diferenças no grau de concordância de juízes com experiência (Kappa moderada) e sem experiência (Kappa baixo) para os julgamentos realizados na condição pré-fonoterapia. O contexto fonético das amostras de fala influenciaram os julgamentos nas condições pré e pós-fonoterapia. Houve maior percentual de acerto para os juízes experientes condição pré-fonoterapia (p-valor <0,001). Conclusão: a experiência dos juízes e composição fonética das amostras de fala influenciam os julgamentos perceptivo-auditivos das AC.

Does contribution of extended vomer flap to palatoplasty affects speech results

Development of normal speech is the primary goal of successful palatoplasty. The purpose of this study was to determine the importance of the contribution of vomer flap to palatoplasty procedure for speech function. Eighty-one children who underwent 2 flap palatoplasty procedures for cleft palate repair between 2002 and 2010 were retrospectively reviewed in 3 groups. Group 1 underwent palatoplasty without contribution of vomer flap. Group 2 underwent palatoplasty with standard dissection of vomer flap, whereas group 3 underwent palatoplasty with extended dissection of vomer flap. Speech function of the patients was evaluated using objective assessment tools such as nasopharyngoscopy and nasometer. Eighty-one children who underwent 2 flap palatoplasty were included in this study. The mean age at palatoplasty was 10.17 months, and mean length of follow-up was 72.33 months. For most syllables, patients repaired using extended vomer flap demonstrated lower nasalance scores. Nasopharyngoscopic examination revealed velopharyngeal motility in 24 patients (80%) in group 1 and in 20 (83.3%) and 23 (85.2%) patients in groups 2 and 3, respectively (P = 0.930). In velopharyngeal closure, there were only 5 patients (18.5%) in group 3, whereas there were 6 patients (25.0%) for group 2 and 10 patients (33.3%) for group 1 with no closure (P = 0.311). Although most optimum results were observed in the group with extended dissection of the vomer flap, contribution of the extended vomer flap to the repair of the soft palate did not lead to significantly better speech results.

The Cleft Care UK study. Part 4: perceptual speech outcomes

OBJECTIVES

To describe the perceptual speech outcomes from the Cleft Care UK (CCUK) study and compare them to the 1998 Clinical Standards Advisory Group (CSAG) audit.

SETTING AND SAMPLE POPULATION

A cross-sectional study of 248 children born with complete unilateral cleft lip and palate, between 1 April 2005 and 31 March 2007 who underwent speech assessment.

MATERIALS AND METHODS

Centre-based specialist speech and language therapists (SLT) took speech audio-video recordings according to nationally agreed guidelines. Two independent listeners undertook the perceptual analysis using the CAPS-A Audit tool. Intra- and inter-rater reliability were tested.

RESULTS

For each speech parameter of intelligibility/distinctiveness, hypernasality, palatal/palatalization, backed to velar/uvular, glottal, weak and nasalized consonants, and nasal realizations, there was strong evidence that speech outcomes were better in the CCUK children compared to CSAG children. The parameters which did not show improvement were nasal emission, nasal turbulence, hyponasality and lateral/lateralization.

CONCLUSION

These results suggest that centralization of cleft care into high volume centres has resulted in improvements in UK speech outcomes in five-year-olds with unilateral cleft lip and palate. This may be associated with the development of a specialized workforce. Nevertheless, there still remains a group of children with significant difficulties at school entry.

Proposal and content validation of an orofacial myofunctional assessment protocol for individuals with cleft lip and palate

PURPOSE

To create and validate the content of an orofacial myofunctional assessment protocol for individuals with cleft lip and palate.

METHODS

The first version of an orofacial myofunctional assessment protocol for individuals with cleft lip and palate was created by two speech-language pathologists, who contemplated the structural and functional aspects of the stomatognathic system. This version was analyzed by other two speech-language pathologists experienced in cleft lip and palate assessment, who suggested changes that led to the second version of the protocol. Dynamic and static images necessary for performing the orofacial myofunctional examination were recorded from three individuals with cleft lip and palate, who represented three life stages: childhood, adolescence, and adulthood. Five examiners evaluated the images, applied the proposed protocol, and judged each item regarding its clarity to validate the content, from Content Validity Index.

RESULTS

The assessment protocol was finalized with 13 items, ten related to structural aspects and three related to functional aspects, with their corresponding sub-items. The general agreement in the validation of its content was 100%, so that only one stage was required.

CONCLUSION

A protocol to evaluate the orofacial myofunctional aspects of individuals with cleft lip and palate was created with 13 items, as well as their corresponding sub-items, and its content was validated.

Progressive Tightening of the Levator Veli Palatini Muscle Improves Velopharyngeal Dysfunction in Early Outcomes of Primary Palatoplasty

BACKGROUND

Management of the levator veli palatini with intravelar veloplasty has been shown to improve speech resonance. The senior author has introduced a more aggressive procedure where the levator is separately dissected, overlapped, and tightened. This study compares resonance results from four levator management protocols: non-intravelar veloplasty, Kriens intravelar veloplasty, radical intravelar veloplasty, and overlapping intravelar veloplasty.

METHODS

Retrospective chart review was conducted on 252 patients who underwent primary palatoplasty with speech follow-up at 3 years of age. Velopharyngeal function was evaluated with perceptual speech examinations, and subjects were scored on a four-point scale (0 = normal resonance; 1 = occasional hypernasality/nasal emission/turbulence/grimacing, no further assessment warranted; 2 = mild hypernasality/intermittent nasal turbulence/grimacing, velopharyngeal imaging suggested; and 3 = severe hypernasality, surgical intervention recommended). Fisher's exact test was used to compare outcomes.

RESULTS

A single surgeon performed all the non-intravelar veloplasty (n = 92), Kriens intravelar veloplasty (n = 103), and radical intravelar veloplasty (n = 31), whereas the senior author performed the overlapping intravelar veloplasty (n = 26). Cleft severity proportions were equivalent across the four methods (p = 0.28). Patients who underwent overlapping intravelar veloplasty demonstrated significantly better velopharyngeal function, and none required further imaging or secondary surgery compared with the other three procedures (p < 0.001).

CONCLUSIONS

Speech resonance outcomes at 3 years of age are improved and need for secondary velopharyngeal dysfunction management is reduced with more aggressive levator dissection and reconstruction during primary one-stage palatoplasty. Results were best when the muscle was overlapped.

Current Controversies in Diagnosis and Management of Cleft Palate and Velopharyngeal Insufficiency

Background. One of the most controversial topics concerning cleft palate is the diagnosis and treatment of velopharyngeal insufficiency (VPI). Objective. This paper reviews current genetic aspects of cleft palate, imaging diagnosis of VPI, the planning of operations for restoring velopharyngeal function during speech, and strategies for speech pathology treatment of articulation disorders in patients with cleft palate. Materials and Methods. An updated review of the scientific literature concerning genetic aspects of cleft palate was carried out. Current strategies for assessing and treating articulation disorders associated with cleft palate were analyzed. Imaging procedures for assessing velopharyngeal closure during speech were reviewed, including a recent method for performing intraoperative videonasopharyngoscopy. Results. Conclusions from the analysis of genetic aspects of syndromic and nonsyndromic cleft palate and their use in its diagnosis and management are presented. Strategies for classifying and treating articulation disorders in patients with cleft palate are presented. Preliminary results of the use of multiplanar videofluoroscopy as an outpatient procedure and intraoperative endoscopy for the planning of operations which aimed to correct VPI are presented. Conclusion. This paper presents current aspects of the diagnosis and management of patients with cleft palate and VPI including 3 main aspects: genetics and genomics, speech pathology and imaging diagnosis, and surgical management.

A Comparative Study to Evaluate the Functional Effect of Unilateral Uvuloplasty after Primary Palatoplasty

Background:

The conventional method for uvular repair suturing the 2 hemi-uvulas of the palatal cleft together in the midline does not allow us to obtain a proper anatomical repair. In our hands, the midline straight closure frequently causes retraction of the uvular tissues with the consequent abnormal appearance of the uvula. We described before a method for uvular repair in patients with cleft palate. The technique consists in preserving one of the hemi-uvulas, which is moved to the midline to form the definitive uvula. The purpose of this study was to evaluate the functional effects of the unilateral uvuloplasty for uvular repair in a group of patients with bilateral cleft palate.

Methods:

This is a retrospective, single-blinded cohort study between 2 groups of 90 patients with bilateral cleft palate who were operated on using the conventional and unilateral uvuloplasty methods of uvular repair from 2000 to 2009. Data collection was accomplished by physical examination to evaluate the presence of postoperative fistulas and hypernasal speech determined at 6 months to 5 years after surgery. In addition, postoperative dimensions of the velopharynx were measured by a single-blind examiner using a computed tomography scan.

Results:

Our comparative study found statistically significant differences between the 2 groups in favor of the unilateral uvuloplasty group.

Conclusions:

We observed that the use of unilateral uvuloplasty for uvular reconstruction reduces the velopharyngeal space and the frequency of hypernasality in patients with bilateral cleft palate.

Impact of inter-judge agreement on perceptual judgment of nasality

PURPOSE

To investigate the effect of perceptual inter-judge agreement of hypernasality on velopharyngeal (VP) closure prediction.

METHODS

Two logistic regression models were developed aiming to verify the possibility of predicting the VP closure using the following characteristics: rating of VP closure (adequate, borderline, inadequate), determined by the pressure-flow technique, degree of hypernasality (absent, mild, moderate, severe), and the presence/absence of nasal air emission and nasal rustle determined perceptually by three experienced speech language pathologists. In the first model, 100 speech samples with a moderate agreement rate of hypernasality (kappa coefficient: 0.41) were used. In the second model, 43 speech samples with a perfect agreement among judges were included. The χ²-test was used to compare the models (p≤0.05).

RESULTS

In the first model, 65 of the 100 samples were rated in the correct VP closure category, with 42 adequate and 23 inadequate. The borderline VP closure was not predicted. The second model rated 31 of the 43 samples in the correct category, with 21 adequate VP closure, 5 in the borderline VP closure, and 5 inadequate. There was no difference (p=0.526) between the two models. However, the second model showed a higher proportion of accuracy (7%) than the first one, and it has also predicted the borderline VP closure.

CONCLUSION

These results showed the importance of high index of inter-judge agreement when using subjective parameters of speech evaluation, especially when compared to an instrumental evaluation. This suggests the need for strategies for training and calibration of judges in the perceptual judgment to improve the reliability of auditory-perceptual assessment.

Acoustic analysis of voice in children with cleft palate and velopharyngeal insufficiency

BACKGROUND

Acoustic analysis of voice can provide instrumental data concerning vocal abnormalities. These findings can be used for monitoring clinical course in cases of voice disorders. Cleft palate severely affects the structure of the vocal tract. Hence, voice quality can also be also affected.

OBJECTIVE

To study whether the main acoustic parameters of voice, including fundamental frequency, shimmer and jitter are significantly different in patients with a repaired cleft palate, as compared with normal children without speech, language and voice disorders.

MATERIALS AND METHODS

Fourteen patients with repaired unilateral cleft lip and palate and persistent or residual velopharyngeal insufficiency (VPI) were studied. A control group was assembled with healthy volunteer subjects matched by age and gender. Hypernasality and nasal emission were perceptually assessed in patients with VPI. Size of the gap as assessed by videonasopharyngoscopy was classified in patients with VPI. Acoustic analysis of voice including Fundamental frequency (F0), shimmer and jitter were compared between patients with VPI and control subjects.

RESULTS

F0 was significantly higher in male patients as compared with male controls. Shimmer was significantly higher in patients with VPI regardless of gender. Moreover, patients with moderate VPI showed a significantly higher shimmer perturbation, regardless of gender.

CONCLUSION

Although future research regarding voice disorders in patients with VPI is needed, at the present time it seems reasonable to include strategies for voice therapy in the speech and language pathology intervention plan for patients with VPI.

Relationship between velopharyngeal closure, hypernasality, nasal air emission and nasal rustle in subjects with repaired cleft palate

PURPOSE: To investigate the correlation among velopharyngeal closure, hypernasality, audible nasal air emission (NAE) and nasal rustle (NR), in individuals with repaired cleft palate. METHODS: One hundred patients with repaired cleft palate and lip, submitted to pressure-flow study for measurement of velopharyngeal orifice area (velopharyngeal area) and speech sample recordings. Velopharyngeal area was estimated during the production of the sound /p/ inserted in a sentence, and the velopharyngeal closure was classified as adequate, borderline or inadequate. Hypernasality was rated using a 4-point scale, NAE and NR were rated as absent or present, by three speech language pathologists, using recorded speech samples. Inter and intra-judge agreements were established. Statistical analysis was performed using the Spearman correlation coefficient considering p<0.05. An ordinal logistic regression model was developed to investigate whether the characteristics of speech can predict velopharyngeal closure. For this, the speech samples included in this analysis were those that obtained 100% agreement among raters as to the degree of hypernasality (43 out of 100). RESULTS: Significant correlation was found between hypernasality and velopharyngeal area; audible NAE and velopharyngeal area. A negative correlation was observed between the NR and velopharyngeal area. The regression analysis showed that the perceptual speech characteristics contributed significantly to predict the velopharyngeal closure. CONCLUSION: There is significant correlation between velopharyngeal closure and hypernasality, NAE and NR. It suggests that the perceptual speech characteristics can predict velopharyngeal closure, favoring the diagnosis and the definition of treatment conduct of velopharyngeal dysfunction.

One-flap Palatoplasty: A Cohort Study to Evaluate a Technique for Unilateral Cleft Palate Repair

Background:

The 2-flap palatoplasty technique is actually the approach most commonly used in the United States for cleft palate repair. This is a one-time surgery that enables closure under minimal tension, lowering rates of subsequent fistula development. However, its primary disadvantage is potential detriment to maxillary growth (due to extent of dissection on both sides of the cleft and raw lateral surfaces). Since 2007, a surgical technique using only one mucoperiosteal flap from the noncleft side has been performed by us, reducing the extent of the surgery and its potential nondesirable effects over the palate. The purpose of this study is to evaluate the utility of this technique for unilateral cleft palate repair.

Methods:

This is a retrospective, simple-blinded cohort study between 2 groups of 120 patients each with unilateral cleft palate who were operated on using the 2-flap and 1-flap techniques by the Outreach Surgical Center Program Lima from 2007 to 2012. Data collection was accomplished by physical examination to evaluate the presence or absence of a fistula and to evaluate the presence of hypernasality. Postoperative bleeding was also studied.

Results:

We have observed no increase in the rate of fistulas and velopharyngeal insufficiency between these 2 studied groups (P = 0.801 and P = 1.000).

Conclusions:

Use of a 1-flap technique for unilateral cleft palate repair allowed us to achieve results comparable to those of a 2-flap technique in terms of postoperative fistula development and hypernasal speech. Additional studies are required to evaluate the effect of this technique on palatal growth.

A randomized controlled trial comparing two techniques for unilateral cleft lip and palate: Growth and speech outcomes during mixed dentition

OBJECTIVE

To study the growth and speech outcomes in children who were operated on for unilateral cleft lip and palate (UCLP) by a single surgeon using two different treatment protocols.

MATERIAL AND METHODS

A total of 200 consecutive patients with nonsyndromic UCLP were randomly allocated to two different treatment protocols. Of the 200 patients, 179 completed the protocol. However, only 85 patients presented for follow-up during the mixed dentition period (7-10 years of age). The following treatment protocol was followed. Protocol 1 consisted of the vomer flap (VF), whereby patients underwent primary lip nose repair and vomer flap for hard palate single-layer closure, followed by soft palate repair 6 months later; Protocol 2 consisted of the two-flap technique (TF), whereby the cleft palate (CP) was repaired by two-flap technique after primary lip and nose repair. GOSLON Yardstick scores for dental arch relation, and speech outcomes based on universal reporting parameters, were noted.

RESULTS

A total of 40 patients in the VF group and 45 in the TF group completed the treatment protocols. The GOSLON scores showed marginally better outcomes in the VF group compared to the TF group. Statistically significant differences were found only in two speech parameters, with better outcomes in the TF group.

CONCLUSIONS

Our results showed marginally better growth outcome in the VF group compared to the TF group. However, the speech outcomes were better in the TF group.

Avaliação da nasalidade de fala na fissura labiopalatina

Objetivo Descrever os resultados da nasalidade de fala de indivíduos com fissura labiopalatina e comparar os achados de nasalidade estabelecidos por meio do julgamento perceptivo-auditivo realizado ao vivo com os achados estabelecidos por análise de gravações por juízes, em dois tipos de amostras de fala. Métodos O estudo envolveu a análise retrospectiva dos resultados de avaliações perceptivo-auditivas da nasalidade de fala realizadas ao vivo por uma fonoaudióloga e o julgamento prospectivo, por consenso de juízas de 100 gravações de amostras de fala, obtidas durante a produção de dois conjuntos de estímulos de fala: um com consoantes de alta pressão (CAP, n=100) e outro com consoantes de baixa pressão (CBP, n=100). Os dados pertenciam a pacientes de ambos os gêneros, com idades entre 5 e 12 anos, que tiveram a fissura labiopalatina operada por um mesmo cirurgião. Resultados A ausência de hipernasalidade foi constatada em 69% dos julgamentos ao vivo. Quando presente, a hipernasalidade leve foi constatada em 23% dos casos, enquanto a hipernasalidade moderada em 8%. Para os julgamentos das amostras gravadas, 50% foram identificadas com hipernasalidade durante a produção das amostras CAP e 62% durante a das amostras CBP. Diferença significativa foi encontrada entre o resultado do julgamento ao vivo e o julgamento pelas juízas nas amostras CAP. A concordância entre as modalidades de avaliação variou de 79% para as amostras CAP e 80% para as amostras CBP, sendo considerada moderada. Conclusão O julgamento perceptivo ao vivo da nasalidade de fala pode detectar melhor a ausência de hipernasalidade, seguida pela hipernasalidade de grau leve, em comparação com o julgamento realizado por juízes múltiplos, a partir de amostras gravadas. Contudo, tem a desvantagem de os dados não poderem ser reproduzidos, nem quantificados, nem compartilhados por outros membros da equipe.

Nasality in Friedreich ataxia

Perceptual speech research in Friedreich ataxia (FRDA) has identified altered nasality as a key component of the dysarthria profile, however the incidence and severity of abnormal nasality remains unknown. Utilizing objective and perceptual methods, data on the relationship between resonance, disease duration, severity, age of onset and genetic profiles were collated. Thirty-seven participants with FRDA and 24 healthy controls provided contemporaneous speech samples for perceptual analysis, and single word samples for acoustic analysis. A subset of participants (eight participants with FRDA and eight controls) underwent nasometry assessment. Twenty-seven participants with FRDA presented with hypernasality and five with hyponasality on perceptual assessment. Acoustic analysis revealed participants with FRDA had greater nasality than controls (p < 0.05). Perceptual ratings of hypernasality correlated with GAA2 repeat length (ρ = 0.37, p = 0.03). Findings highlight the variability of nasality in FRDA, potentially reflecting variation in the neuropathological profile. Data also suggest the influence of genetic profiles on nasality.

Instrumental assessment of velopharyngeal function and resonance: a review

The purpose of this literature review is to describe and discuss instrumental assessment techniques of the velopharyngeal function in order to diagnose velopharyngeal disorders and resonance characteristics. Both direct and indirect assessment techniques are addressed, in which successively nasopharyngoscopy, videofluoroscopy, magnetic resonance imaging (MRI), cephalometric radiographic analysis, computed tomography (CT), ultrasound, acoustic and aerodynamic measurements are considered. Despite the multiple instrumental assessments available to detect and define velopharyngeal dysfunction, the ideal technique is not yet accessible. Therefore, a combination of different quantitative parameters can possibly form a solution for a more reliable determination of resonance disorders. These multi-dimensional approaches will be described and discussed. The combination of quantitative measurement techniques and perceptual evaluation of nasality will probably remain necessary to provide sufficient information to make appropriate decisions concerning the diagnosis and treatment of resonance disorders.

LEARNING OUTCOMES

The reader will be able to describe and discuss currently available instrumental techniques to assess the velopharyngeal mechanism and its functioning in order to diagnose velopharyngeal disorders. Additionally, he will be able to explain the possible advantages of the combination of several types of complementary measurement techniques.

Surgical impact and speech outcome at 2.5 years after one- or two-stage cleft palate closure

OBJECTIVE

In the ongoing discussion about timing of palate closure, it is said that early closure is favorable for speech development, but can interfere with maxillary growth. On the other hand, beneficial results on both after one-stage palate closure have also been presented. The assumption that one-stage palate closure leads to less surgical impact on the child probably contributed to the choice for this procedure in most cleft centers. However, no previous research has verified this assumption. The aim of the present study is to compare surgical impact and speech outcome at 2.5 years of age between children who underwent either one- or early two-stage palate closure.

METHODS

Patients underwent either one-stage palate closure between 2007 and 2010 at a median age of 10.8 months (group 1, n=24) or early two-stage closure before 2007 at median ages of 10.4 and 18.2 months, respectively (group 2, n=24). Surgical impact was compared between the two groups by means of duration of surgery, length of hospital stay and number of post-operative complications. Speech outcome was compared by means of resonance problems, nasal air emission, articulation and intelligibility, all assessed at a median age of 2.5 years.

RESULTS

The one-stage closure group showed significantly shorter duration of surgery and length of hospital stay (p<0.001 and p=0.001, respectively) and significantly better articulation (p=0.029) than the early two-stage closure group.

CONCLUSION

One-stage palate closure is preferable over early two-stage palate closure with regard to surgical impact and speech development. More extensive, prospective studies, in which maxillary growth is taken into account, should be conducted.

Nasalance during use of pharyngeal and glottal place of production

Purpose:This study obtained nasalance scores during use of compensatory articulation (CA) and compared nasalance between groups with and without hypernasality and with and without CA.Methods:Speech samples were obtained from 43 individuals with and without velopharyngeal dysfunction during repetition of 20 phrases originating 860 audio recordings and their respective nasometric values. After excluding 143 recordings due to low quality, the remaining 717 samples were rated by three speech language pathologists (SLPs), independently, for presence or absence of hypernasality and CA. Nasalance scores for the 553 samples rated with 100% agreement among the SLPs were grouped according to the auditory-perceptual ratings: Group 1 (G1) - included samples without hypernasality and without CA (n=191); Group2 (G2) - included samples with hypernasality and without CA (n=288); Group 3 (G3) - included samples with hypernasality and with pharyngeal fricative (n=33); Group 4 (G4) - included samples with hypernasality and with glottal stop (n=41).Results:Analysis of variance (ANOVA) revealed significant difference nasalance scores which were significantly higher for G2, G3, and G4 (p<0.0001) when compared to G1. The use of pharyngeal fricative (G3), particularly during /f/ (p=0.0018) and /s/ (p=0.0017) productions resulted in nasalance scores significantly higher than scores found for G2.Conclusion:Significantly higher nasalance values where identified during use of pharyngeal fricative.

Velopharyngeal dysfunction in children with Prader-Willi syndrome after adenotonsillectomy

INTRODUCTION

Prader-Willi syndrome (PWS) is a rare genetic disorder with an incidence rate of 1 in 10,000-30,000. Patients with PWS typically have symptoms related to hypotonia, obesity, and hypothalamic dysfunction. A high rate of obstructive sleep apnea (OSA) is found among this population of patients. Adenotonsillectomy has been advocated as a first line approach for treatment of OSA in patients with PWS. Velopharyngeal dysfunction (VPD) is a known complication of adenotonsillectomy. VPD can also be present in patients with global hypotonia, such as those with PWS. The objective of this study is to review the occurrence of VPD in patients with PWS after adenotonsillectomy for OSA.

METHODS

A retrospective review was performed of all patients with PWS and OSA from a tertiary pediatric hospital between the years of 2002 and 2012. Pre- and post-operative sleep studies and sleep disordered breathing symptoms, post-operative VPD assessment by the speech-language pathologist (SLP), and VPD treatments were evaluated.

RESULTS

Eleven patients (five males and six females), fitting the inclusion criteria, were identified. The age of the patient at the initial otolaryngologic evaluation ranged from 2 to 9 years. All patients underwent adenotonsillectomy for sleep disordered breathing. Four patients were diagnosed with post-operative hypernasality after assessment by a speech-language pathologist. The hypernasality ranged from mild to moderately severe. Of the four patients with hypernasality, two were found to have structural issues requiring surgery (pharyngeal flap). Both of the surgical patients experienced significant improvement in their VPD after surgery. The remaining two patients were found to have articulation error patterns that were considered more developmental in nature and both responded to speech therapy. All patients, except one, had improvement in their polysomnogram or sleep symptoms after adenotonsillectomy. However, three patients continue to require continuous positive airway pressure at night.

CONCLUSION

Velopharyngeal dysfunction may occur after adenotonsillectomy in patients with Prader-Willi Syndrome. Families should be counseled of this risk and the potential need for operative intervention to correct it.

Prevalence and types of articulation errors in Saudi Arabic-speaking children with repaired cleft lip and palate

OBJECTIVES

The purpose of this study was to assess prevalence and types of consonant production errors and phonological processes in Saudi Arabic-speaking children with repaired cleft lip and palate, and to determine the relationship between frequency of errors on one hand and the type of the cleft. Possible relationship between age, gender and frequency of errors was also investigated.

METHODS

Eighty Saudi children with repaired cleft lip and palate aged 6-15 years (mean 6.7 years), underwent speech, language, and hearing evaluation. The diagnosis of articulation deficits was based on the results of an Arabic articulation test. Phonological processes were reported based on the productivity scale of a minimum 20% of occurrence. Diagnosis of nasality was based on a 5-point scale that reflects severity from 0 through 4. All participants underwent intraoral examination, informal language assessment, and hearing evaluation to assess their speech and language abilities. The Chi-Square test for independence was used to analyze the results of consonant production as a function of type of CLP and age.

RESULTS

Out of 80 participants with CLP, 21 participants had normal articulation and resonance, 59 of participants (74%) showed speech abnormalities. Twenty-one of these 59 participants showed only articulation errors; 17 showed only hypernasality; and 21 showed both articulation and resonance deficits. CAs were observed in 20 participant. The productive phonological processes were consonant backing, final consonant deletion, gliding, and stopping. At age 6 and older, 37% of participants had persisting hearing loss.

CONCLUSIONS

Despite early age at time of surgery (mean 6.7 months) for the studied CLP participants in this study, a substantial number of them demonstrated articulation errors and hypernasality. The results showed desirable findings for diverse languages. It is especially interesting to consider the prevalence of glottal stops and pharyngeal fricatives in a population for whom these sound are phonemic.

Self-reported speech problems in adolescents and young adults with 22q11.2 deletion syndrome: a cross-sectional cohort study

Background

Speech problems are a common clinical feature of the 22q11.2 deletion syndrome. The objectives of this study were to inventory the speech history and current self-reported speech rating of adolescents and young adults, and examine the possible variables influencing the current speech ratings, including cleft palate, surgery, speech and language therapy, intelligence quotient, and age at assessment.

Methods

In this cross-sectional cohort study, 50 adolescents and young adults with the 22q11.2 deletion syndrome (ages, 12-26 years, 67% female) filled out questionnaires. A neuropsychologist administered an age-appropriate intelligence quotient test. The demographics, histories, and intelligence of patients with normal speech (speech rating=1) were compared to those of patients with different speech (speech rating>1).

Results

Of the 50 patients, a minority (26%) had a cleft palate, nearly half (46%) underwent a pharyngoplasty, and all (100%) had speech and language therapy. Poorer speech ratings were correlated with more years of speech and language therapy (Spearman's correlation= 0.418, P=0.004; 95% confidence interval, 0.145-0.632). Only 34% had normal speech ratings. The groups with normal and different speech were not significantly different with respect to the demographic variables; a history of cleft palate, surgery, or speech and language therapy; and the intelligence quotient.

Conclusions

All adolescents and young adults with the 22q11.2 deletion syndrome had undergone speech and language therapy, and nearly half of them underwent pharyngoplasty. Only 34% attained normal speech ratings. Those with poorer speech ratings had speech and language therapy for more years.

Ocorrência de ceceio em fricativas vozeadas e não vozeadas em crianças com fissura labiopalatina operada

Objetivo investigar se o ceceio, quando identificado, difere entre as fricativas alveolares não vozeadas e vozeadas produzidas por crianças com fissura labiopalatina operada. Métodos estudo prospectivo, em que frases constituídas pelas consoantes [s] e [z] produzidas por 32 crianças com fissura labiopalatina operada (idade média, 8 anos, 8 meses) foram selecionadas de um banco de dados e posteriormente julgadas auditivamente. Todas as crianças apresentavam relação inter-arcos alteradas, conforme avaliação ortodôntica realizada por três ortodontistas (concordância inter-juiz quase perfeita, kappa= 0.81), a partir da análise de modelos de gesso. Três fonoaudiólogas julgaram auditivamente as produções áudio gravadas. A concordância inter-juízes variou entre 56% e 78% e entre 59% e 93% para as frases constituídas de [s] e [z], respectivamente. Resultados o ceceio foi identificado em 69% das crianças e, particularmente, em 72% e 50% das produções envolvendo [s] e [z], respectivamente. Houve diferença significante entre os julgamentos para as fricativas [s] e [z], com maior ocorrência de ceceio em [s]. Conclusões deformidades dentofaciais podem favorecer a ocorrência do ceceio na população com fissura labiopalatina. A maior ocorrência do ceceio em [s] em comparação à [z], a partir da identificação auditiva, pode ser justificado por razões acústicas e/ou articulatórias. Sugere-se que o ceceio é dependente do contexto fonético-fonológico da frase devendo o mesmo ser considerado para fins clínicos e de pesquisa.

A Cross-Sectional Cohort Study of Speech in Five-Year-Olds with Cleft Palate ± Lip to Support Development of National Audit Standards

Objective

To develop national standards for speech outcomes and processes of care for children with cleft palate ± lip and to test the standards using national data.

Design, Setting, and Participants

In this large, multicenter, prospective cohort study, speech recordings of 1110 five-year-olds with cleft palate involvement (born 2001 to 2003) were collected by 12 cleft centers in Great Britain and Ireland. Recordings were analyzed by consensus by specialist speech and language therapists using the Cleft Audit Protocol for Speech-Augmented. Results were benchmarked against evidence-based process and speech outcome standards and statistical analysis undertaken.

Results

From the 1110 children audited, 48% (530) had speech within the normal range. This was not significantly different from the agreed standard of 50% ( P = .20, CI = 45–50%). Sixty-six percent (734) had speech with no evidence of structurally related speech problems or history of speech-related secondary surgery. This was significantly below the standard of 70% ( P =.007, CI = 62–69%). Sixty percent (666) had no serious cleft-related articulation errors. This was significantly better than the agreed standard of 50% ( P < .001, CI = 67–73%). More than 80% of 2-year-olds received a specialist speech and language assessment against a benchmark of 100%.

Conclusions

Developing standards has facilitated more meaningful reporting of speech outcomes and treatment processes. Evidence-based standards were defined and extensively tested, enabling centers to compare their performance with national trends. One 5-year outcome standard was achievable; the other two standards will require modification through the mandatory annual national audit program.

Speech outcome in complete unilateral cleft lip and palate - a comparison of three methods of the hard palate closure

The aim of this study was to compare the speech in subjects with cleft lip and palate, in whom three methods of the hard palate closure were used. One hundred and thirty-seven children (96 boys, 41 girls; mean age = 12 years, SD = 1·2) with complete unilateral cleft lip and palate (CUCLP) operated by a single surgeon with a one-stage method were evaluated. The management of the cleft lip and soft palate was comparable in all subjects; for hard palate repair, three different methods were used: bilateral von Langenbeck closure (b-vL group, n = 39), unilateral von Langenbeck closure (u-vL group, n = 56) and vomerplasty (v-p group, n = 42). Speech was assessed: (i) perceptually for the presence of a) hypernasality, b) compensatory articulations (CAs), c) audible nasal air emissions (ANE) and d) speech intelligibility; (ii) for the presence of compensatory facial grimacing, (iii) with clinical intra-oral evaluation and (iv) with videonasendoscopy. A total rate of hypernasality requiring pharyngoplasty was 5·1%; total incidence post-oral compensatory articulations (CAs) was 2·2%. The overall speech intelligibility was good in 84·7% of cases. Oronasal fistulas (ONFs) occurred in 15·7% b-vL subjects, 7·1% u-vL subjects and 50% v-p subjects (P < 0·001). No statistically significant intergroup differences for hypernasality, CAs and intelligibility were found (P > 0·1). In conclusion, the speech after early one-stage repair of CUCLP was satisfactory. The method of hard palate repair affected the incidence of ONFs, which, however, caused relatively mild and inconsistent speech errors.

Association between symptoms of sleep-disordered breathing and speech in children with craniofacial malformations

STUDY OBJECTIVE

Sleep-disordered breathing (SDB) and speech difficulties are common problems in children with craniofacial malformations (CFM). The present study was designed to investigate whether resonance issues identified during speech assessment are associated with parental report of SDB symptoms in children with CFM.

METHODS

Children aged 2-18 years with congenital CFM attending at the Craniofacial Anomalies Program from March 2007 to April 2011 were screened for SDB symptoms using the Sleep-Related Breathing Disturbance Scale of the Pediatric Sleep Questionnaire. Speech evaluation, based on the Pittsburgh Weighted Speech Scale score, was the tool used to investigate velopharyngeal dysfunction (VPD) based on speech perceptual assessment.

RESULTS

A total of 488 children with congenital CFM were included. Overall 81% were Caucasian and 24% were overweight/obese. Twenty-four percent of children screened positive for SDB and 35% had VPD. Children with VPD were no more likely to screen positive for SDB than children without VPD (26% vs. 23%, p = 0.38). However, children with previous sphincter pharyngoplasty (SP) were more likely to have hyponasality (51% vs. 12%, p = 0.0001) and reduced or absent nasal emission (33% vs. 16%, p = 0.008). In a logistic regression, the adjusted odds ratio for SDB for those with hyponasality was 2.10 (95%CI 1.21-3.61, p = 0.008) and for those with reduced or absent nasal emission was 1.75 (95%CI 1.06-2.88, p = 0.028).

CONCLUSION

Symptoms of sleep disordered breathing are common in children with craniofacial malformations especially if they have undergone sphincter pharyngoplasty; many of these children can be identified by measures of resonance on routine speech evaluation.
