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

Otol Neurotol. 2014 Dec;35(10):1752-4. doi: 10.1097/MAO.0000000000000509.

Abstract

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.
