Abstract
PURPOSE: We aimed to analyse the reasons behind the need for cochlear implant revision surgeries, as well as the rate at which they occur, to reduce the revision surgery rate for non-device failures. We also aimed to elucidate the cumulative survival and device survival rates in different age groups. METHODS: This retrospective single cohort study reviewed 4563 cochlear implant surgeries and 119 revision surgeries performed at a tertiary referral hospital in China between 1996 and 2019. Kaplan-Meier curves were used to calculate the cumulative survival and device survival rates. RESULTS: The revision surgery rate was 2.61%. The reasons for revision included device (73.1%) and non-device (26.9%) failures. The most common reasons were hard device (47.1%) and non-device failure (28.6%). The 10- and 20-year cumulative survival rates were 96.8% and 96.7%, respectively. Younger children were more likely to undergo a second surgery. CONCLUSION: This study is the longest study about revision surgery in China. Cochlear implantation is a reliable treatment. It has a low complication rate in patients with sensorineural hearing loss. Children have a higher revision rate than adults. Doctors should be aware of each complication and perform the appropriate procedure.
