Abstract

68 cases of glottic carcinomas (T1 53 and T2 15 cases) treated with CO₂ laser or KTP/532 laser April 1982 through March 1992 were reviewed. The patients were followed up from 13 to 130 months (mean 60 months). The 3-year determinate survival rate was 100% and 5-year determinate survival rate was 100% for T1 and 80% for T2. The voice conservation rate was 97% for T1a, 83% for T1b, and 80% for T2 and vocal function was satisfactorily preserved for daily life. The results led to the following conclusions: (1) Glottic T1 carcinomas can be treated by laser surgery alone. (2) Lesions involving the anterior commissure can be treated by laser excision and vaporization. (3) Laser surgery followed by external radiation therapy for glottic T2 carcinomas improves the voice conservation rate.
