Abstract:ObjectiveTo summarize the causes of revision cochlear implantation in 17 cases, explore the methods to reduce the risk of revision cochlea implantation, and improve the satisfaction of surgical treatment and the level of postoperative hearing speech rehabilitation.MethodsClinical data of 17 patients underwent revision cochlea implantation via facial recess approach in Hainan Hospital, Chinese PLA General Hospital from Nov 2012 to July 2018 were analyzed retrospectively to summarize the reasons of revision implantation.ResultsThe causes for revision implantation in the 17 patients were different, including implant failure in 6 cases, implant inoperation in 2, implant damage after impact in 2, displacement of implant receiving device in one, rupture of implant receiving device in one, skin flap infection in 3, incomplete insertion of electrode in one, and removal of the old implant with ipsilateral reimplantation of a late model implant in response to patient’s demand in one. Revision cochlea implantation was successfully completed in all the 17 patients with high satisfaction to the outcomes. Their cochlear aided hearing thresholds and speech discrimination ability were greatly improved with promoted hearing speech rehabilitation effect.ConclusionThe causes of revision cochlear implantation are complicated and varied, and the key to avoid revision implantation is to choose suitable materials of implant, avoid severe impact, perform strict aseptic operation and accurate preoperative evaluation.
