Abstract
Limited anterior pyriform sinus carcinomas can be treated by hemicricolaryngopharyngectomy with preservation of voice and swallowing. The surgical specimen includes the homolateral half of the hypopharynx, larynx, and cricoid ring. The pharynx is reconstructed with a pectoralis myocutaneous flap. A semirigid mucosa-lined dynamic speech tube is created by folding in the remaining half of the larynx. This tube, which is 4 to 5 mm in diameter, serves as a phonatory structure. Speech is produced by occluding the stoma with the finger and shunting air into the oral cavity. Patients maintain a permanent tracheostomy.
