Pharyngocutaneous fistulas in advanced cancer: closure with musculocutaneous or muscle flaps.

Two hundred cases of head and neck cancer were reviewed and 16 pharyngocutaneous fistulas identified, for an incidence of 6 percent. The fistulas were closed with pectoralis major muscle flaps in four patients, pectoralis musculocutaneous flaps in seven patients, sternocleidomastoid muscle flaps in four patients, and latissimus dorsi flaps in two patients. Four types of fistulas were identified, and flap selection was determined by fistula location. Successful closure was obtained in 15 patients (88 percent), although one patient died from recurrence with a persistent fistula.
