BackgroundThe anterolateral thigh myocutaneous flap is one of the most commonly used flaps in reconstructive procedures, but its application in oral and maxillofacial defects has not been fully determined. Herein, we summarize the application of 1212 anterolateral thigh myocutaneous flaps in the repair of oral and maxillofacial defects and examine their benefits in maxillofacial reconstruction of these defects.MethodsPatients were recruited from February 2002 to June 2013 in the Department of Oral and Maxillofacial Surgery of Central South University. All patients underwent reconstructive surgery employing anterolateral thigh myocutaneous flaps. Patient ages ranged from 6 to 82 years with a mean age of 51.2 years. There are 1015 flaps showing single lobe and 197 flaps showing a multi-island pedicle and one of which carries the iliac bone. The largest area among the single flaps was 28 × 12 cm(2), and the smallest was 3 × 2 cm(2).ResultsAmong the 1212 transferred flaps, 1176 survived and 36 showed necrosis, a survival rate of about 97.0%. The common complications at flap donor site were poor wound healing (10.1%), localized paraesthesia (50.1%), and altered quadriceps force (11.0%). No cases presented with local serious complications, and 90% of patients achieved good functional recovery and aesthetically acceptable results after reconstruction of oral and maxillofacial defects at various locations using anterolateral thigh myocutaneous flaps. The time (23-121 min; average 51 min) for anastomosis of one vein and one artery was significantly less than that for two veins and one artery (45-153 min, average 83 min; p = 0.0003), which indicates one vein anastomosis can significantly reduce the operating time.ConclusionThe anterolateral thigh myocutaneous flaps can be easily obtained and can provide a good amount of muscle for filling dead space and fascia lata. These flaps can be prepared into a separate fat flap, multi-island fascia with iliac bone, and other composite pedicle flaps to meet the various requirements of oral and maxillofacial defects. The subcutaneous fat thickness of the anterolateral area can vary considerably and thus can be used to repair defects requiring different flap thickness. Therefore, the anterolateral thigh myocutaneous free flaps are more suitable for oral and maxillofacial defects than other flaps.Copyright © 2014 European Association for Cranio-Maxillo-Facial Surgery.
