New Approach for Superthin Anterolateral Thigh Flap Elevation

Abstract

Background Anterolateral thigh (ALT) flaps are widely used for soft tissue reconstructions. They have several advantages, most notably a long pedicle, an appropriate pedicle caliber, low donor site morbidity, and the possibility of 2 teams working simultaneously. However, conventional, thick ALT flaps used for reconstructions of head and neck and lower extremity defects may cause postoperative range of motion limitations and cosmetic problems. The aim of this study was to develop and propose strategies to facilitate the harvest of superthin ALT flaps and minimize technical difficulties. This article provides step-by-step instructions for simple, quick, and reliable dissections of superthin ALT flaps. Methods This study retrospectively analyzed data from 60 free superthin ALT flaps used for soft tissue reconstructions in 56 patients between January 2018 and February 2019. Superthin flaps were elevated just above the superficial Scarpa's fascia using a vertical approach. Results Thirty-eight of the patients were operated on for lower extremity wounds, 16 were for head and neck defects, and 6 were for upper extremity wounds. The mean follow-up period was 7 months. The median hospital stay was 10 days. Total flap loss was observed in 4 cases (6.6%), and partial flap loss was observed in another 4 cases (6.6%). Conclusions The superthin elevated ALT flap is a reliable and effective option for the reconstruction of soft tissue defects. In our vertical approach, the wide field of view of the flap perforator provides easy dissection, making it easier to elevate the superthin ALT flap.
