Abstract
Partial laryngopharyngectomy (PLP) has not been frequently adopted for hypopharyngeal cancer.Problems of PLP were swallowing dysfunction after surgery and poor safety margin. To preventswallowing dysfunction, we developed a new method of reconstruction in which the supraglottis wasbuilt by using a half of the hyoid bone attached to the sternohyoid muscle pedicle while a wide lumenof hypopharynx was formed with a forearm flap. To improve the safety margin, histopathological examinations in several sites of resected margins were performed during surgery. Five patients withT2 piriform sinus cancers were treated with this surgery. Voice and respiration were well conservedin all patients. Swallowing function after surgery was satisfactory in most patients. Recurrence ofcancer did not occur in any patient. PLP can be an alternative treatment for piriform sinus cancer, especially in moderately clinical stages.
