Exposed cochlear implant coverage with temporalis muscle flap.
J Sharif Med Dent Coll Jan ;3(1):19-22.

Objective: The purpose of this study is to evaluate the use of the temporalis muscle flap as second layer coverage after cochlear implant extrusion. Methodology: This is a multicenter study in which cochlear implant extrusion complication was managed in eight patients by two layer closure; temporalis muscle flap used as salvage layer for cochlear implant coverage and scalp rotational flap as a routine coverage. Six months postoperative follow-up was observed. Results: Total eight patients with cochlear implant extrusion were managed by using double layers closure; seven out of eight patients had no evidence of implant extrusion during 6 months follow-up. Except for one patient no complication was noticed. In one case implant was removed due to flap necrosis and another patient developed hematoma postoperatively, which was managed by surgical evacuation, later on flap healed uneventfully. The results showed that using temporalis muscle flap two layered closure had a significant role in salvage of secondary extruded cochlear implant. Conclusion: Temporalis muscle flap as the first layer in combination with scalp rotational flap as secondary coverage of implant had superior results in secondary cochlear implant extrusion prevention. Keywords: Cochlear implant. Temporalis muscle flap. Scalp rotational flap.
