Spontaneous Bone Bed Formation in Cochlear Implantation Using the Subperiosteal Pocket Technique

Objective: To show evidence of spontaneous bone pocket formation using the subperiosteal pocket technique for cochlear implantation surgery. 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.
