Reconstruction after orbital exenteration using gracilis muscle free flap.

BackgroundOrbital exenteration (OE) is a disfiguring procedure, which typically includes the removal of the entire eyeball including the globe, extraocular muscles, and periorbital soft tissues after malignancies excision or trauma. Several methods of orbital reconstruction have been attempted with varying success. In this report, we analyze results of the use of gracilis muscle free flap for reconstruction of OE defects and its feasibility for prosthetic rehabilitation. MethodsNine consecutive patients treated at the China Medical University Hospital of Taichung during January 2009 to January 2013, who had gracilis free flap reconstruction after OEs, were retrospectively reviewed. Cancer in six patients and trauma in remaining three patients was the cause for OE. ResultsNine patients who underwent reconstruction with gracilis free tissue transfer had a successful outcome. There was not any donor or recipient site morbidity; however, one patient was deceased during follow-up period due to metastasis. The mean follow-up period was 23.5 months. Cosmetic results were acceptable both to patients and to surgeons. ConclusionsGracilis free flap to repair OE defects may be a safe alternative for reconstruction. It provides a larger volume of well-vascularized tissue, greater placement flexibility, and minor donor site morbidity without any significant functional deficit. (c) 2014 Wiley Periodicals, Inc.
