Insights
Children with non-syndromic cleft lip and palate (NSCLP) show abnormal auditory brainstem responses (ABR), binaural interaction component (BIC), and auditory late latency responses (ALLR), indicating a higher risk for central auditory processing disorder.
Area of Science:
- Pediatric audiology
- Neuroscience
- Genetics
Background:
- Non-syndromic cleft lip and palate (NSCLP) is a common congenital condition.
- Central auditory processing abilities in children with NSCLP are not fully understood.
Purpose of the Study:
- To compare central auditory processing abilities in children with NSCLP versus controls.
- To investigate the utility of electrophysiological tests in assessing auditory processing in NSCLP.
Main Methods:
- Electrophysiological assessment of 30 children (7-15 years) with NSCLP and craniofacially typical controls.
- Auditory brainstem responses (ABR), binaural interaction component (BIC), auditory late latency responses (ALLR), and P300 were evaluated.
Main Results:
- Children with NSCLP exhibited deviant ABR, BIC, and ALLR.
- No significant differences in P300 were found between groups.
Conclusions:
- Children with NSCLP may have an increased risk of central auditory processing disorder.
- Electrophysiological tests are valuable for assessing neural transmission in NSCLP auditory pathways.
Abstract:
BackgroundThe present study compared the central auditory processing abilities using electrophysiological tests in children with non-syndromic cleft lip and palate (NSCLP) and their age-matched control group.MethodThirty children aged 7 to 15 years were recruited for the study. Participants were divided into 2 groups. The clinical group (children with NSCLP) comprised 15 children, while the control group (craniofacially typical peers) comprised 15 children with normal hearing sensitivity and auditory processing skills. Electrophysiological tests, including auditory brainstem responses (ABR), binaural interaction component (BIC) of ABR, auditory late latency responses (ALLR), and P300 were assessed.ResultsThe results showed deviant responses in ABR, BIC, and ALLR in children with NSCLP compared to craniofacially typical counterparts. However, no significant difference was observed in P300 between the two groups.ConclusionChildren with NSCLP may be at a higher risk of central auditory processing disorder due to their abnormal neural transmission in the auditory nervous system. Also, assessing auditory processing abilities in children with NSCLP should include electrophysiological tests in the test battery for additional information regarding neural transmission.
