Abstract
Advanced-stage lesions of the hypopharynx or tongue base often involve the larynx. The difficulty of reconstructing large partial laryngopharyngeal defects can result in total laryngectomy being performed to avoid the assumed problems with aspiration. This article describes the first reported experience using the pectoralis musculocutaneous flap for primary one-stage reconstruction of laryngopharyngeal defects following resection of advanced-stage lesions, to reconstruct both the laryngeal and the pharyngeal components of the defect. In this group of 21 patients, there were 16 with hypopharyngeal and 5 with tongue base cancers. Two had received prior treatment, and all received some form of postoperative radiotherapy and/or chemotherapy. Six patients experienced complications, including two fistulae, three wound infections, two myocardial infarctions, and one colon perforation. There were no instances of stenosis of the reconstructed segment. The length of hospitalization ranged from 9 to 60 days, the average being 17 days. Forty-seven percent (21) of the patients were not tolerating an oral diet at the time of discharge. However, 15 patients (71%) ultimately were eating by mouth, with 13 (62%) achieving an oral intake of liquids and solids. This analysis supports the hypothesis that the pectoralis major musculocutaneous flap is an effective one-stage primary reconstruction technique for laryngopharyngeal defects in patients either who have received prior therapy or who will receive postoperative therapy.
