ABSTRACT

Hypopharyngeal carcinoma is an aggressive malignancy that usually presents at a late stage, thereby resulting in an overall poor prognosis fir these unfortunate patients. The most effective treatment of pyriform sinus carcinoma combines surgery and radiation. Total laryngopharyngectomy is necessary in advanced tumors, but may not be appropriate in limited lesions. Therefore several procedure for partial laryngopharyngectomy have been proposed. Supracricoid hemilaryngopharyngectomy is the one of these procedure. This report presents one case of supracricoid hemilaryngopharyngectomy in a patient with pyriform sinus medial wall cancer and analyses aerodynamic study before and after operation.
