Abstract
Clinical experiences with transoral CO2 laser resections of glottic and supraglottic carcinomas are presented. 47 patients with variously sized supraglottic tumors and 114 patients with early glottic cancers were treated at the University of Kiel from 1979 to 1993. Although 10 patients with glottic tumors developed recurrences, curative treatment was possible with either repeat laser surgery (3 cases), irradiation (3 cases) or salvage laryngectomy (3 cases). One patient refused further treatment. Among the 30 patients with supraglottic lesions treated for cure 18 are currently alive and free of disease. 6 patients died with no evidence of disease, 2 patients died from secondary malignancies and 3 patients succumbed to their tumors. Present findings justify routine use of laser resections of laryngeal neoplasms, although patients must still be carefully selected for treatment.
