Subtotal pharyngolaryngectomy conservation surgery for carcinoma of sinus pyriformis extending toward the larynx.
In newly developed surgery for pyriform sinus tumor extending toward the larynx, the supraglottic portion of the larynx and the vertical half of the larynx on the tumor side are included in the area of resection. The arytenoid and cricoid cartilages on the tumor side and the vertical half of the hypopharyngeal wall are resected. Three out of seven patients remain cured at the end of 5 years and this ratio is the same as that for total pharyngolaryngectomy for pyriform sinus tumor. The resulting voice is somewhat hoarse, however, verbal communication is not remarkably affected. It is concluded that in surgical repair for pyriform sinus tumor extending toward the larynx, subtotal pharyngolaryngectomy is the procedure of choice to preserve the laryngeal function and anticipate reasonable prospects for a cure.
