Summary :
Background: We conducted a retrospective case review of patients with mastoid cavity and active or inactive chronic otitis media (COM) who underwent cochlear implantation and ear obliteration in a single-stage procedure. The objectives of this review are to assess the rates of complications and postoperative infections and to evaluate post-implantation audiologic performance. Materials and methods: All patients with COM and mastoid cavity, associated or not with active disease, who undergo cochlear implantation and obliteration of the ear as a single-stage procedure from November 2004 to April 2013, were included in the review. All the complications were recorded. Open-set sentence scores were used to evaluate the audiologic gain after implantation. Results: Twenty-seven patients were included in our review: ten with active COM and seventeen with inactive COM. Overall, nine patients (9/27) presented postoperative complications (7/9 were minor): three were amongst active COM patients (30%) as compared to six amongst inactive COM patients (35%), which included the two major complications. A mean gain of 55.9% on open-set sentence scores was obtained after cochlear implantation. Discussion: We found that complications rate of the one-stage cochlear implantation was higher in patients with COM than in global implant population, but most complications were minors and there was no statistical difference between active and inactive COM. In addition, these patients had audiologic scores similar to those found in patients with normal temporal bone anatomy. Conclusion: Cochlear implantation performed as a one-stage procedure could be considered as an option of treatment to avoid staging in patients with active and inactive COM. Although these patients need a regular follow-up, they present good post-implantation audiometric scores.
