Laryngeal Function after Supracricoid Laryngectomy with Cricohyoidoepiglottopexy

Abstract

Twenty-four supracricoid laryngectomies with cricohyoidoepiglottopexy (CHEP) were performed for selected patients with laryngeal cancer in our institutions since December 2000. A retrospective chart review was performed to assess postoperative speech and swallowing function. Strobography and video fluorography of the neoglottis were utilized to assess speech and swallowing kinetics. Acoustic parameters were measured to evaluate vocal function and furthermore, several questionnaires were employed to evaluate the postoperative quality of life (QOL) of the patients. Without postoperative complications, stoma closure and normal diet intake were achieved 1 month after surgery. The neoglottis consists of the arytenoid (s), epiglottis and pyriform sinus mucosa. Several different combination patterns of these regions were observed between patients. The distance of laryngeal elevation and the width of the entrance to the esophagus were not affected by the surgical procedure, making normal diet intake possible. Even though vocalization sounded rough and breathy, vocal communication was possible with little inconvenience. Acceptable functional recovery and a tolerable QOL could be obtained after CHEP.
