Outcomes of using a modified anteromedial thigh perforator flap for repairing the anterolateral thigh free flap donor site: A retrospective clinical review

The anterolateral thigh (ALT) flap plays an essential part in plastic and reconstructive surgery. However, repair of the anterolateral donor site has not been the focus of the clinicians. To assess the clinical value and feasibility of using a modified anteromedial thigh (AMT) perforator flap for repairing the ALT free flap donor site. In this retrospective study, 16 ALT flaps were transferred to resurface large soft-tissue defects (ranged from 7 x 5 to 13 x 8cm) in the foot or hand from June 2012 to March 2013. The donor sites were repaired with an advancement flap pedicled with an AMT perforator. Sensation within the advancement flap, return-to-work (RTW) time, the aesthetic appearance of the donor sites, and functional recovery were measured. All 15 flaps survived completely without necrosis. One flap developed partial necrosis in the tip but healed with dressing changes after 1 week. The medain follow-up period was 3.5 months (range, 3-6 months). The average median time was 9.5 weeks (range 8-13 weeks). There was no numbness of the advancement flap. Additionally, there was no specific complication at both the recipient and donor sites. Thigh quadriceps muscle strength and activities of the knee were normal. All patients were satisfied with the aesthetic outcome postoperatively at the 3-month to 6-month follow-up. The modified advancement flap pedicled with an AMT perforator is an ideal option for repairing the anterolateral donor site.
