“…Besides the subtotal petrosectomy, several surgical techniques to insert a cochlear implant in patients with COM with a RMC are described in literature [11, 12, 16–18]. Three other alternative surgical approaches are reported in literature which can be carried out either combined with cochlear implantation, as a single-stage procedure or as a staged procedure.…”

The purpose of this paper is to propose management options for cochlear implantation in chronic otitis media (COM) based on our 7-year experience. Thirteen patients with COM who were candidates for cochlear implantation were identified. COM was divided in an inactive and an active form based on clinical and radiological findings. One major complications and one minor complication were identified in the study group. In case of an active infection or in case of a unstable cavity we advise cochlear implantation as a staged procedure. A single stage procedure is recommended in case of patients with COM presenting with a dry perforation or a stable cavity.

“…Various surgical methods have been described for preventing extrusion of the electrode array in an open cavity. Most of those techniques make use of autologous tissues or pedicled muscles to cover the electrode array without cavity obliteration [Manrique et al, 1996;Himi et al, 1997]. We believe that these covering methods are not complete, as it is possible DOI: 10.1159/000505509 for the covering materials to be absorbed with time, as seen with our patient.…”

Cochlear Implantation in Patients with Chronic Suppurative Otitis Media: Surgical Outcomes and a Management Algorithm

Background: Chronic suppurative otitis media (CSOM) was considered as a contraindication of cochlear implantation (CI) in the past. Recently, various surgical options have been adopted for CI in CSOM patients with showing a low complication rate. Objectives: To evaluate surgical outcomes of CI in patients with CSOM and to propose a management algorithm for those patients. Methods: Thirty-six consecutive patients with CSOM who underwent single stage or staged CI were enrolled. Speech performance, including Categories of Auditory Performance (CAP) test and sentence score, and complications were retrospectively analyzed. Results: The average follow-up was 3.1 years (range 0.5-9.2 years). Postoperative median CAP and sentence scores were 6 and 78%, respectively. Three (8.3%) of the 36 patients had postoperative complications. One experienced breakdown of the ear canal closure. Recurrence of the pars tensa retraction was observed in another patient with adhesive otitis media who underwent CI and cartilage tympanoplasty as a single stage operation. Electrode extrusion occurred in another patient who underwent staged CI with maintenance of a previous open cavity. Subtotal petrosectomy and cavity obliteration were used to manage the latter 2 complications. All implant patients with good mastoid pneumatization exhibited no complications. There were no significant differences in postoperative speech performance and complication rates between single stage CI and staged CI. Based on these current findings, a management algorithm was proposed according to type of CSOM, presence of open cavity, and mastoid pneumatization. Conclusions: Patients with CSOM show good postoperative speech performance after CI. Proper surgical options according to type of CSOM, presence of open cavity, and mastoid pneumatization may help in reducing complications.

“…The single-stage procedure is sufficient for stable disease if the radical mastoid cavity can be obliterated well enough to protect the electrode array (Axon et al, 1997;Hamzavi et al, 2001). Manrique et al (1996) proposed covering methods to avoid electrode exposure in a stable radical cavity. They anchored the electrode array to the facial ridge using Ionos cement, and then covered the array with autologous tragal cartilage and temporalis muscle facia.…”
