23 patients with vocal cord carcinoma, presenting no changes in the cord motility (T1N0) have been treated in E.N.T. Department of Catania University with an endoscopic surgical cordectomy with CO2 laser. Compared with the traditional surgical systems, endoscopic cordectomies with CO2 laser have advantages in the technical field : the wide vision of the lesion and the remarkable precision by using a surgical microscope ; in the biological field : reduction of risks coming from a possible neoplastic spreading ; in the clinical field : little traumatism, absence of œdema and secondary inflammatory processes. To get good results from this surgical treatment it is necessary to have the possibility of an adequate exposure of larynx and to respect surgical indications.
