Background:
Orbital exenteration is a severe and disabling surgical procedure that involves the removal of all orbital contents. Effective reconstruction is crucial to managing the resulting defects. This study aims to propose a reconstructive algorithm utilizing free flaps derived from the lateral circumflex femoral artery (LCFA) system for orbital exenteration defects, based on our clinical experience.
Patients And Methods:
Patients who underwent orbital exenteration and subsequent reconstruction using LCFA-based free flaps between January 2013 and January 2022 were included in this study.
Results:
A total of 44 patients underwent orbital exenteration, followed by LCFA free flap reconstruction. The choice of reconstructive technique depended on defect type and dura mater exposure, adhering to the proposed algorithm. The procedures included 20 standard ALT (Anterolateral thigh) flaps, 13 chimeric ALT flaps, 1 SALT chimeric flap with skin grafting, 7 SALT flaps with skin grafting, and 3 buried SALT flaps. Complications were recorded in 10 cases at the recipient site and 2 cases at the donor site.
Conclusion:
Orbital exenteration presents significant challenges both surgically and reconstructively, with a high risk of local recurrence and postoperative mortality. The reconstruction algorithm using LCFA-based free flaps, as proposed in this study, may guide surgeons in selecting the most appropriate technique, tailored to the specific defect and considering postoperative treatments such as adjuvant radiotherapy.
