Abstract :
Congenital deafness can hinder speech and language acquisition with significant negative consequences on a child’s educational and psychosocial development. Cochlear implantation has become an accepted treatment in children with profound sensorineural heå loss. Aims and objectives: The study aimed at correlating the outcome of cochlear implantation surgery in the form of intra operative neural response telemetry (NRT), functional auditory performance indicators (FAPI) and assessment of language development (ALD) with the pre operative imaging findings. Materials and methods: A cohort study was conducted during January 2015 to May 2016 in the Department of Radiodiagnosis, Government Medical college Kozhikode. 84 subjects under 5 years underwent preop imaging . Intra operative monitoring of neural response was done using neural response telemetry. Functional auditory performance indicators and assessment of language development were measured at 12th month after the surgery and auditory verbal therapy. The data were entered in the Microsoft excel and the analysis was done using SPSS software version 18. Results:.Cochlear nerve deficiency and narrow bony canal for cochlear nerve were the two important findings that consistently correlated with poor post post–operative outcome; and the association was found to be statistically significant (p value < 0.001).No significant association was obtained between dimensions of cochlea or cochlear nerve thickness with intra operative NRT. Conclusion: HRCT of the temporal bone and MRI play an important role in the evaluation and in the management of congenital sensorineural heå loss. A thorough knowledge of the imaging anatomy of the middle and inner ear enables the radiologist to provide a structured report, which help the clinician in the proper pre–operative counseling, uneventful surgery and in the prediction of a realistic post–operative outcome.
