Abstract
We developed a new surgical method to prevent aspiration after partial laryngopharyngectomy for piriform sinus carcinoma. After removing the epiglottis and arytenoid on the affected side, half of the hyoid bone connecting to the sternohyoid muscle was fixed to the thyroid and the epiglottic cartilages to reconstruct the epiglottis. A protrusion of the arytenoid was formed with the sternohyoid muscle sutured to the excised end of the arytenoid on the unaffected side. Using a free forearm flap, the supraglottis was covered, and the piriform sinus was reconstructed.
This surgery was performed for a patient with T2N0 piriform sinus carcinoma. Three weeks after surgery, the tracheal stoma was closed and the oral intake of food was begun. The voice was normal. The respiratory and swallowing functions were satisfactory without any dyspnea or aspiration.
