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.
