Spontaneous bone bed formation in cochlear implantation using the subperiosteal pocket technique

Abstract

Study Design: Clinical capsule report.Setting: University hospital.Patients: We evaluated 8 pediatric revision cochlear implant patients who had previously undergone cochlear implantation using the subperiosteal pocket technique. The time between primary and revision surgery varied between 5 and 54 months.Results: Spontaneous bone bed formation for the internal receiver stimulator and its electrodes was observed during revision surgeries in all patients.Conclusion: The subperiosteal pocket technique for cochlear implantation does not require pockets to be drilled in the skull, unlike the standard technique, because bone beds form spontaneously.Objective: To show evidence of spontaneous bone pocket formation using the subperiosteal pocket technique for cochlear implantation surgery. © 2014, Otology & Neurotology, Inc.
