Correction of Orbital Implant Exposure Using A Supra-Brow Island Flap Pedicled with Orbicularis Oculi Muscle.

Purpose: To describe our experience of the supra-brow island flap pedicled with orbicularis oculi muscle technique for correcting orbit implant exposure. Materials: and methods: This retrospective study reviewed 32 patients underwent orbit implant exposure surgery using a supra-brow island flap pedicled with orbicularis oculi muscle autograft. All data were reviewed from patients in Eye & ENT Hospital of Fudan University, Shanghai during 2018.1-2020.7. Patient demographics, the original etiology, surgical procedures, implant types, and follow-up interval were recorded. Main outcome was the long-term coverage of implant after a supra-brow island flap pedicled with orbicularis oculi muscle autograft; the rate of post-surgical complications and management were secondary outcome. Results: : 28 eyes of 32 patients had functional results and satisfactory cosmetic at final follow up(range, 9-29 months). In 4 patients, recurrence of exposure was recorded during follow-up and in two of these patients using DFG was performed, one patient was treated conservatively, one patient refused treatment. There were no clinically significant complications. Conclusions: : A supra-brow island flap pedicled with orbicularis oculi muscle autograft could be a reliable technique to manage or to prevent orbital implant exposure irrespective of primary surgery, exposed area, and implant material.
