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.
