Behavioral assessment of auditory processing disorder in children with non-syndromic cleft lip and/or palate

Central Auditory Processing Abilities in Children with Non-Syndromic Cleft Lip/and Palate-a Behavioural Study

The present study aimed to assess the central auditory processing abilities and working memory in children with non-syndromic cleft lip and palate (NSCLP) and to compare with the developed normative and craniofacially normal peers. Sixteen NSCLP children aged 7 to 12 years and fifteen craniofacially normal peers were recruited in this study. Speech perception in noise Kannada (SPIN-K), gap detection threshold (GDT), dichotic consonant-vowel (DCV), and masking level difference (MLD) tests were administered to assess various central auditory processing abilities. Working memory abilities were assessed by using forward-digit span and backward-digit span tests. The results showed significant differences in SPIN-K, dichotic CV, GDT, forward digit, and backward digit span scores between children with NSCLP and craniofacially normal peers. Thus, it can be concluded from the present study that children with NSCLP have a risk of developing auditory processing deficits. To conclude, assessment of central auditory processing abilities in children with NSCLP is recommended.

The relationship between auditory behaviours and speech and language development in children with cleft lip and palate

PURPOSE OF REVIEW

Children born with a cleft lip and palate (CLP) are at risk of speech problems. There is a high prevalence of conductive hearing loss due to otitis media with effusion and recent research has highlighted broader difficulties with language and educational attainment. There has been increased interest in the impact of auditory processing on a child's development, but little study into links between auditory skills and speech and language development.

RECENT FINDINGS

Children with CLP consistently struggle with auditory tasks. Difficulties processing words in a noisy background, auditory attention and temporal processing are frequently reported. A recent study in the United Kingdom investigated the auditory behaviours of 95 children aged 5-8 years with nonsyndromic CLP and compared these with speech and language profiles. Auditory difficulties correlated with speech development and most auditory behaviours correlated with language outcomes. There was also a correlation of language with speech outcomes, suggesting a more complex and interdependent relationship.

SUMMARY

Children with CLP present with high levels of difficulties with auditory skills. The potential impact of this on broader development needs further research, but clinicians should ensure that auditory skills beyond the hearing test are monitored, and advice given to parents to minimize the impact.

Auditory and language skills in children with cleft lip and palate

OBJECTIVES

to investigate auditory and language skills in children with repaired cleft lip and palate.

METHODS

The sample was composed of 22 children registered at the hospital where the study was conducted, seven to nine years old, 50% being female, with repaired unilateral cleft lip and palate (right or left), without associated malformations. Auditory skills were assessed using four central auditory processing tests: Random Gap Detection Test, Dichotic Digit Test, Dichotic Non-Verbal Test, Sustained Auditory Attention Ability Test. Language performance was evaluated by four standardized instruments: Illinois Psycholinguistic Skills Test, Peabody Picture Vocabulary Test, Token Test and Phonological Skills Profile. The association between auditory and language skills was evaluated by the Fisher exact test at a significance level of 5% (p<.05).

RESULTS

The central auditory processing tests evidenced that only one child presented adequate performance in all skills analysed, five children presented impaired performance in all skills, and 16 exhibited deteriorations in one to three auditory skills, highlighting that temporal resolution was the most impaired skill (81%). Concerning language, three children presented adequate performance in all tests applied, and Visual Association and Auditory Association were the most impaired skills (40%). No association was observed between deteriorations in auditory and language skills.

CONCLUSION

There was high occurrence of impairment of auditory skills, which compose the central auditory processing, as well as of language skills, with greatest impairment of receptive language.

Linguistic and auditory processing skills in non-syndromic children with cleft palate: A scoping review

BACKGROUND

Cleft lip and/or palate (CL/P) is the most common congenital craniofacial condition. Children born with CL/P are at increased risk of persistent speech difficulties related to velopharyngeal incompetence (VPI) and compensatory articulation problems. It has also been reported that they achieve poorer results academically than their peers. There is a further body of evidence to suggest delayed language skills. These potentially related outcomes are often reported separately.

AIM

To review published and unpublished research into the nature of difficulties related to spoken and written language across all non-syndromic cleft diagnoses. To review any evidence of associations between comorbidities.

METHOD

A scoping review was carried out in October 2016 and updated in June 2019 following published methodology (Arksey & O'Malley, 2005; Levac et al. 2010).

RESULTS

A search of the literature over the two time points found 38 papers in total. Three main themes were found: oral language skills, reading and auditory processing difficulties.

CONCLUSIONS

There is evidence of early language delay in children born with CL/P. Evidence of persistent oral language problems is less conclusive. Many studies have reported scores within the average range for language, auditory processing and reading but poorer outcomes when compared to non-cleft control groups. However, studies have used a range of outcome measures, making comparisons difficult. Moreover there is no clear evidence how these difficulties might relate to speech outcomes or educational achievement and no comparison to other populations with speech, language and communication needs (SLCN).

A Preliminary Dynamic Investigation on Velopharyngeal Movements During Blowing: A New Approach for Evaluation

PURPOSE

To explore an alternative approach to evaluate velopharyngeal function on those speakers with compensatory misarticulation.

METHOD

Nasopharyngeal endoscopy was used to observe the velopharyngeal movement on 26 adult Mandarin speakers during articulation and different nonverbal state, including SCPS, DCPS, and ABS.

RESULTS

There were significant differences for the rate of velopharyngeal incompetence (RVPI) among the 4 different states. The RVPI was least for the Articulation State, followed by the Air Blowing and DCPS. The RVPI was largest for the SCPS.

CONCLUSION

The result indicated that the ABS may be used as an alternative approach to evaluate the velopharyngeal function instead of the articulation samples while patients cannot make clear articulation due to compensatory misarticulation habits. It merits further study on nonverbal activities, which could lay a foundation for exploring more effective approach for evaluation of the velopharyngeal function.

Electrophysiological assessment of auditory processing disorder in children with non-syndromic cleft lip and/or palate

Objectives

Cleft lip and/or palate is a common congenital craniofacial malformation found worldwide. A frequently associated disorder is conductive hearing loss, and this disorder has been thoroughly investigated in children with non-syndromic cleft lip and/or palate (NSCL/P). However, analysis of auditory processing function is rarely reported for this population, although this issue should not be ignored since abnormal auditory cortical structures have been found in populations with cleft disorders. The present study utilized electrophysiological tests to assess the auditory status of a large group of children with NSCL/P, and investigated whether this group had less robust central auditory processing abilities compared to craniofacially normal children.

Methods

146 children with NSCL/P who had normal peripheral hearing thresholds, and 60 craniofacially normal children aged from 6 to 15 years, were recruited. Electrophysiological tests, including auditory brainstem response (ABR), P1-N1-P2 complex, and P300 component recording, were conducted.

Results

ABR and N1 wave latencies were significantly prolonged in children with NSCL/P. An atypical developmental trend was found for long latency potentials in children with cleft compared to control group children. Children with unilateral cleft lip and palate showed a greater level of abnormal results compared with other cleft subgroups, whereas the cleft lip subgroup had the most robust responses for all tests.

Conclusion

Children with NSCL/P may have slower than normal neural transmission times between the peripheral auditory nerve and brainstem. Possible delayed development of myelination and synaptogenesis may also influence auditory processing function in this population. Present research outcomes were consistent with previous, smaller sample size, electrophysiological studies on infants and children with cleft lip/palate disorders. In view of the these findings, and reports of educational disadvantage associated with cleft disorders, further research that focuses on the auditory processing abilities of children with cleft lip/palate disorder is warranted.
