Facial reconstruction with thinned anterolateral thigh free flap

Abstract

Abstract Facial reconstruction is challenging for plastic surgeons, as it can be difficult to decide the best approach. One technique that has been widely used is the anterolateral thigh (ALT) flap due to its numerous benefits. However, its thickness can be a drawback, especially regarding facial reconstruction. The thinning technique is not a new novel, but how to apply it to the ALT flap to get the best result hasn’t been reported yet. Our study involved 117 patients, and we used 73 thinned ALT flaps to determine the best method to increase the flap’s safety. After thinning, we significantly reduced the flap’s thickness from an average of 22.5 mm to 5.9 mm, making it more suitable for contouring purposes. We apply a thinned ALT flap for coverage, contouring, and recreating the facial 3D structure. The 12/45 flap has the chance to make the multiple-paddle ALT flap, which helps to reconstruct difficult positions even more flexibly. The key to successfully thinning the ALT flap is understanding the perforator’s structure and pathway through the fascia. With the thinning technique, we have overcome the limitations of the flap’s thickness, making it suitable for use in whole-body reconstruction. The ALT flap can overcome the restriction of its thickness and can be applied even more extensively in whole-body reconstruction.
