Early glottic cancer is usually treated with radiotherapy; however, throat discomfort due to radiation-induced xerostomia frequently affects the quality of life for patients. The occurrence of radiation-induced cancer especially in younger patients, as well as second primary head and neck cancer, particularly in elderly patients, are additional potential side effects of this treatment. Therefore surgery involving laser microsurgery can also be considered for untreated early laryngeal cancer. Only one in fifteen patients treated with laser microsurgery for untreated T1aN0M0 glottic cancer had a recurrence during the follow-up period. Evaluation of postoperative voice with the visual analog scale (VAS) demonstrated 70％ satisfaction compared with that of 76％ in eleven T1aN0M0 glottic cancer patients treated with radiotherapy during same period. These results suggest that laser microsurgery can be an optional treatment for T1a glottic cancer with a satisfactory control rate as well as postoperative voice.
