Reconstruction following radical maxillectomy with flaps supplied by the subscapular artery

Abstract

The authors present their experience of 27 cases with repairs of defects following radical maxillectomies with free flaps. A total of 28 flaps were used (five latissimus dorsi, six scapula, 16 combination flaps of scapula and latissimus dorsi and one combination of scapula, latissimus dorsi and serratus anterior flap). Only one scapula flap was completely lost and in three cases where a combination of scapula and latissimus dorsi flap was used, partial necrosis of one component occurred. The authors first choice for reconstruction is a scapula bone flap raised on the angular artery combined with the latissimus dorsi flap. The combination of flaps with a long pedicle and of the bony and muscular components provides the surgeon with the option of customizing the flap to meet individual patient needs. For intraoral closure the authors prefer the latissimus dorsi muscle which rarely requires secondary procedures for prosthesis placement following epithelialization and atrophy. The main disadvantage of the flap is the difficulty of two teams working simultaneously, thus increasing the average operating time. All postoperative corrections and prosthetic rehabilitation should be postponed for at least 2 months following surgery because of postoperative swelling.
