Abstrakt: Aims: Subtotal petrosectomy (SP) with cochlear implant (CI) is required in certain specific situations in the management of patients who are candidates for cochlear implants. To study and review the indications, surgical issues, and complications of this procedure.
Materials and Methods: Retrospective review of all patients who underwent subtotal petrosectomy with cochlear implant during the period January 2010-December 2016 at a tertiary care and referral centre.
Results: 19 patients underwent 20 subtotal petrosectomy with cochlear implant during this period. One patient had simultaneous bilateral implantation. The indications were previous mastoid cavity in 7 patients, 5 patients had chronic otitis media, inner ear malformations in 3,ossified cochlea in 3 and unfavourable anatomy in 2 patients. Fat or musculoperiosteal flaps were used to obliterate the cavity. Ninety percent of patients underwent single stage surgery and ten percent underwent two stage procedure.Complications were seen in three patients (15%).
Conclusion: SP helps in isolating the cavity from external environment after removal of disease, improves the exposure and access, reduces risk of infection and cerebrospinal fluid (CSF) leaks and facilitates CI. Meticulous surgical technique will reduce the complications and long term follow up is needed to detect entrapped cholesteatoma. Subtotal petrosectomy with blind sac closure of external ear canal is required in certain specific situations. It is a safe and effective surgery with acceptable rate of complications.
