HORIZONTOVERTICAL LARYNGECTOMY FOR SUPRAGLOTTIC CARCINOMA

Recent decades have seen the expansion of Indications for partial lary ngectomy. This study focused on the application of horizontovertical l aryngectomy for T2 and selected T3 and T4 supraglottic carcinomas. An osteomuscular flap was designed to reconstruct the laryngeal defect to preserve all the essential laryngeal functions. Seventy-six patients treated between November 1979 and October 1990 were reviewed retrospec tively. All but two were followed up for at least 5 years. There were 11 cases of T2, 57 cases of T3, and 8 cases of T4 tumors. The survival rates of 7 cases of stage II, 56 cases of stage III, and 13 cases of stage IV carcinoma were 100%, 84.3%, and 74.3%, respectively, The func tional recovery was satisfactory; 78.4% of 74 patients underwent decan nulation, and all but one patient resumed a normal diet. this study sh owed that conservation surgery is reliable for selected supraglottic c ancers, even for those lesions that extend beyond the confines of the supraglottis.
