Abstract:
To describe clinico-demographical profile for post-lingual hearing loss in the adults undergoing cochlear implantation and their outcomes. A retrospective chart review was conducted including adult patients (> 18 years) with bilateral post-lingual severe to profound hearing loss who underwent cochlear implantation in a tertiary care hospital of north India. The clinico-demographical details were collected and the outcomes of the procedure were assessed in terms of speech intelligibility scores, usage and satisfaction scores. Twenty-one patients were included with a mean age of 38.6 years with 15 males and 6 females. The major cause of deafness was infections followed by ototoxicity. The complication rate was 4.8%. Preoperative SDS was not recordable in any of the patients. The mean postoperative SDS was 74%, with no issue of device malfunction in a mean follow-up of 44 months. Cochlear implantation is a safe surgery with good outcomes in post-lingually deafened adults with the major cause for deafness being infections.
