We performed endoscopic laser surgery for the treatment of post-irradiation recurrences of T1 and T2 laryngeal carcinomas. Two out of the 5 T1 glottic type carcinoma cases and 1 out of the 4 T2 cases were controlled after the laser surgery. Recurrences in the successfully treated cases were confined to the vocal cords. In 2 out of the 4 supraglottic type patients, the recurrences were confined to the false vocal cords and were controlled after the laser surgery. These findings suggest that small recurrences after irradiation can be controlled by endoscopic laser surgery.
