Outcomes of cochlear implantation in patients with incomplete partition type III

Abstract

ObjectiveTo evaluate the outcomes of the surgery of cochlear implantation (CI) in patients with incomplete partition type III. MethodsFive patients (6 ears) with incomplete partition type III were performed CI from January 2010 and July 2018. Five ears were performed CI with extended round window approach. One ear was performed with round window approach. ResultsThe results of computed tomography (CT) showed proper placement of the electrode in 5 ears with extended round window approach. The electrode went into the internal auditory canal in one ear with round window approach. The scores of patients in the CAP and SIR assessment significantly improved after cochlear implantation in all patients during an follow-up period of 12 months. ConclusionsCI with extended round window approach in patients with incomplete partition type III is a safe and effective method, but also a challenging task. This method maybe avoid the problem of electrode insertion into the IAC.
