Abstract
Fourteen patients with laryngeal tumors were treated using CO2 laser equipment at our clinic from March 1983 to November 1984. In this study, we paid special attention to the healing of the mucosal wound after laser surgery, and evaluated the significance of the application of laser surgery in the treatment of those tumors. The results are summarized as follows; 1) In 5 cases of laryngeal carcinoma, laser surgery was effective in reducing mass lesions before radiation therapy. In most cases, the region of the vocal fold injured by laser beam was covered with a white coating for a few months after the end of radiatin therapy. It appears that laser therapy in laryngeal carcinoma should be applied to the depth of the vocal ligament. 2) In 7 cases of laryngeal epithelial hyperplasia, a white coating remained for about one month. It seems that laser vaporization may be applied to the depth of the vocal ligament at the initial operation. 3) Two cases of laryngeal papilloma were treated using laser therapy. The first was a case of solid mass lesion which was cured by laser surgery only. The second was a case of multiple mass lesion which remains after three unsuccessful laser surgery.
