[A study of 16 cases on the island pectoralis major muscle flap in repair for the defects after the laryngeal function reserved operation of hypopharyngeal carcinoma].

ABSTRACT

Objective:To explore the application about island pectoralis major muscle flap in repair for the defects after the laryngeal function reserved operation of hypopharyngeal carcinoma.Method:A retrospective analysis about 16 patients who underwent hypopharyngeal carcinoma surgery using pedicle island pectoralis major myocutaneous flap to repair, including 14 cases whose primary tumors located in the piriform fossa, and 2 cases in pharynx posterior wall.Result:All 16 cases' pectoralis major muscle flap survived, 2 of patient appeared to have a pharyngeal fistula, but recovered after transition. Of the 16 cases, 14 cases were removed the trachea tube in 1-3 months, 2 cases survive with tube, and all patients were satisfied with their appearance and the function. In 16 cases, 2 of them survived 3 and a half years, died of lung metastasis; 2 cases survived for four years, 1 died of local recurrence of tumor and another died of heart disease; 1 survived for four and a half years and died of lung metastasis; the remaining 11 cases were still in follow-up.Conclusion:The application in the surgical defect repair of pharyngeal carcinoma with pedicle island pectoralis major myocutaneous flap is safe and effective.
