title: Transoral carbon dioxide laser resection of supraglottic carcinoma.
abstract: Between 1981 and 1994, 34 patients with squamous cell carcinoma of the supraglottis were treated by transoral carbon dioxide laser resection, 12 of them palliatively. Additional treatment included neck dissection in 21 patients and radiotherapy in 24 patients. The 3-year overall survival was 62%, and the actuarial survival 80%. The overall survival for T1 and T2 tumors was 71%, and that for T3 and T4 tumors was 47%. The overall 3-year survival for the early stages, I and II, was 88%, and that for the advanced stages, III and IV, was 50%. These results are comparable to the outcome after conventional open partial resection. Given the significantly lower morbidity (only 7 patients required tracheostomy), we do not observe an age limit anymore. The transoral method can be recommended as curative treatment in T1 and T2 tumors and in selected T3 and T4 tumors in concert with neck dissection and/or radiotherapy. In patients with advanced inoperable tumors, laser surgery is an excellent alternative to tracheostomy and palliative radiotherapy. Prerequisites for successful application of the transoral carbon dioxide laser resection are adequate resection techniques.
