The purpose of this study was to review the operative method, the functional evaluation and the treatment outcome of cases treated for hypopharyngeal cancer whose could be sustained by preserving laryngeal function.<BR>[Method] In case it was determined that there was less tumor invasion of the larynx, the primary tumor was extracted while partially retaining the larynx. This procedure, a pharyngectomy with partial laryngectomy, was chosen with the intent of preserving phonation for hypopharyngeal cancer patients. Modified surgery was avoid as much as possible. The tracheal stoma was closed to the maximum potential extent.<BR>A phase operation was favorably considered in order to accomplish our aim of minimizing the resected area while aggressively resecting the tumor. This was achieved by neoadjuvant chemotherapy and postoperative concurrent chemo-radiation therapy.<BR>[Result] Between 1999 and 2004, 31 cases with hypopharyngeal cancer underwent treatment. Eight cases (26%) had function preservation surgery in 20 cases (65%) that primary lesion treated with the adaptive operation.<BR>As a result, 11 cases received only neck dissection; the laryngeal function preservation totaled 19 cases (61%). Phonation and oral intake were possible in all the cases that received functional preservation surgery of larynx. Distant metastasis was recognized in one case; however, the cumulative average survival time was 24.6±12.8 months.<BR>[Conclusion] We suggest the utilization of laryngeal function preservation surgery for hypopharyngeal cancer patients.
