Clinical Outcomes Following Revision Cochlear Implantation: A Single-Center Experience.

Abstract

Objective: Cochlear implant surgery enables individuals with severe hearing loss to regain auditory function. With the increasing number of implant recipients, complications have become more common, leading to a greater need for revision procedures. This study aimed to analyze and assess the underlying causes of revision surgeries performed in our clinic.

Methods: This retrospective study reviewed 1,800 patients who underwent cochlear implantation in our clinic. Of these, 118 patients who required revision operations were included in the analysis. Causes of revision, observed complications, and demographic profiles of the patients were studied.

Results: No significant differences were found in age, gender, implantation side, presence of inner ear anomalies, or etiology between patients with and without complications (p>0.05). Complications were observed in 22.9% of female patients (n=11) and 8.6% of male patients (n=6). The cochlear implant brand, failure type (soft or hard), and revision indication were not statistically related to complication status (p>0.05). Although not significant, complication rates were higher among patients who required revision due to device malfunction or cholesteatoma.

Conclusion: Revision cochlear implantation should be considered in patients presenting with symptoms such as hearing deterioration, tinnitus, pain or swelling at the implant site, redness, delayed wound healing, or atypical facial sensations. This study summarizes our clinical experience and highlights the primary causes leading to revision cochlear implantation.
