Insights
Children with non-syndromic cleft lip and palate (NSCLP) show deficits in auditory processing and working memory compared to peers. Early assessment of central auditory processing is recommended for these children.
Area of Science:
- Neuroscience
- Developmental Pediatrics
- Audiology
Background:
- Non-syndromic cleft lip and palate (NSCLP) can impact various developmental aspects.
- Central auditory processing and working memory are crucial for language and cognitive development.
Purpose of the Study:
- To evaluate central auditory processing abilities and working memory in children with NSCLP.
- To compare these abilities between NSCLP children and craniofacially normal peers.
Main Methods:
- Utilized Speech Perception in Noise Kannada (SPIN-K), Gap Detection Threshold (GDT), Dichotic Consonant-Vowel (DCV), and Masking Level Difference (MLD) tests.
- Assessed working memory using forward and backward digit span tests.
- Recruited 16 NSCLP children (7-12 years) and 15 craniofacially normal peers.
Main Results:
- Significant differences were observed in SPIN-K, DCV, GDT, forward digit span, and backward digit span scores.
- NSCLP children demonstrated poorer performance in auditory processing and working memory tasks.
Conclusions:
- Children with NSCLP are at risk for developing auditory processing deficits.
- Routine assessment of central auditory processing abilities is recommended for children with NSCLP.
Abstract:
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.
