CO2 laser was applied via laryngomicrosurgery to 36 laryngeal cancer (glottis) patients from April, 1982 to March, 1988. Seven cases were not cured by laser and underwent laryngectomy. The patients were followed up for 9 to 80 months (mean 38 months). Thirty-five cases (97%) are survived without an evidence of recurrence. From this follow-up study we concluded as follows: 1) T1a can be treated by laser alone. 2) T1b can be treated by laser alone or by a combination of laser and radiation, and 3) a careful selection of cases for laser use is required in T2.
