| Abstract: | Pectoralis major myocutaneous flap is the most commonly used versatile flap in head and neck reconstructive surgery. The use of entirely tubed pectoralis major myocutaneous flap for reconstruction of the hypopharynx following total laryngectomy and total pharyngectomy has a disadvantage of bulkiness of the flap and poor postoperative deglutition. One-stage reconstruction of the entire hypopharynx utilizing a combination of pectoralis major myocutaneous flap and dermal graft minimizes bulkiness, thus achieving satisfactory to excellent functional results. The operation has been performed on four patients with excellent deglutition. The pectoralis major myocutaneous flap is utilized to reconstruct the anterior and lateral walls of the hypopharynx, the dermal graft for the posterior wall as far superior as the vault of the nasopharynx. The operative procedure is described. Pectoralis major myocutaneous flap usually provides enough length to reach the distant site of the surgical defect. On occasion, however, additional length is desirable to avoid tension along the suture line. This becomes apparent when a random portion of elevated pectoralis major myocutaneous flap presents questionable viability which may require further trimming. Resection of the medial half of the clavicle can provide additional length of this flap by 2 cm to 2.5 cm. |
