Abstract: Objective: To investigate the methods with a fascial flap of the strap muscles in reconstruction for hypopharyngeal carcinoma. Methods: Nine patients with hypopharyngeal cancer (stage Ⅱ, 1; stage Ⅲ, 4; and stage Ⅳ, 4; according to the UICC 2002 staging criteria) were surgically treated from June 1987 to June 1997. Lateral pharynx approaches were chosen based on the condition of process to perform the ablation of tumors, and fascial flap/muscular flap/ muscularfascial flap of the strap muscles were used to repair the defects and reconstruct the functions of larynx and pharynx. Adjutant radiation therapy of 6080Gy was performed on all cases. Results: All repair materials used were alive. One case suffered from postoperative wound infection and healed after constant rinsing and dressing changes. Two cases suffered from pharyngeal fistula and healed after dressing changes, rinsing and pressurizing. All patients′ laryngeal functions were preserved. All patients recovered diet within 12 to 35 days, with a mean time of 16.3 days. No pharyngosterosis and esophagostenosis happened. The 3 and 5year survival rates were 66.7%(6/9) and 44.4%(4/9), respectively. Conclusion: It is an available way to repair the defect of the hypopharyngeal paries anterior and the base of tongue with fascial flap/muscularflap/ muscularfascial flap of the strap muscles.
