Abstract
Introduction: Children with auditory neuropathy spectrum disorder (ANSD) generally struggle with auditory and language treatment, and cochlear implants' (CIs') outcomes can be unpredictable. environmental noise. The speech discrimination ability is the main complaint of those patients especially in background Objective: Assessment of the ability of young children diagnosed with ANSD who underwent CI in one ear to discriminate speech by using "speech in noise test" with 0 Signal to noise ratio (S/N) and comparing them with matched children with severe to profound sensori-neural hearing loss (SNHL). Methods: The study was conducted on 27 children who received "unilateral" CI of different companies divided into 2 groups: the control group 15 children with severe to profound (SNHL) and (ANSD) group 12 children. All children subjected to following evaluation 2 years post regular auditory language re habilitation: aided cortical auditory evoked potentials (CAEP) in which latency of P1 was analyzed, Speech discrimination score (SD%), (SPIN) score test with 0 S/N ratio, Categories of auditory performance (CAP), Speech intelligibility rate (SIR). Results: 75% of ANSD group showed response in aided CAEP and SD% and SPIN test with no significant difference between groups as regards to age, Latency of P1, CAP and SIR, the mean ±SD of the SD% score in control group was 89.9±2.6while it was64±4.9 in ANSD group the SPIN score with mean ±SD was 85.6±and 51.7±7.4 in controls and ANSD groups respectively, a significant negative correlation between P1 Latency associated with SPIN% in ANSD group was recorded. As regard CAP and SIR there was no significant difference between the study and the control group following 2 years of regular rehabilitation; indicting the beneficial effect of CI and "auditory language rehabilitation" in children with ANSD. Conclusion: CI in "ANSD" children had a positive impact on language development, and the outcomes were on par with those children without "ANSD". Our study also highlighted that the SPIN score test is very important in determining how well CI works, especially for individual with "ANSD".
