OBJECTIVES: Aim of present study is to compare audiological and surgical outcomes in prelingual deaf children with Mondini's dysplasia (MD) and those with normal inner ear anatomy.

MATERIALS and METHODS: Retrospective data was collected from Jan 2008 to Dec 2016. Children with bony IEM other than MD, syndromic association, multiple disabilities, those lost to follow up, and perilingual or postlingual deafness were excluded from study. Audiological outcomes for auditory perception (CAP score) and speech intelligibility (SIR score) was noted for a follow up period of 1 year.

RESULTS: Mean age at implantation was 2.8 years (Range of 2 to 6 years). 2 patients had intraoperative CSF ooze which was controlled intraoperatively by conservative measures. Post operative facial nerve function was normal in all patients. None of the patient in either group had any complications at one year of follow up period. There was statistically significant improvement in CAP & SIR score in Group A at 6 & 12 months compared to pretreatment. There was no statistically significant difference between the 2 groups in terms of CAP & SIR score at 6 & 12 months.

CONCLUSION: The study stresses the fact that cochlear implantation can be safely performed in children with MD although there is a risk of intraoperative CSF leak which can be controlled intraoperatively. Cochlear implantation in children with MD has good surgical, auditory and speech outcomes at par with children with normal bony inner ear anatomy.
