title: [Long-term results of treatment in T1, T2 laryngeal cancer with CO2 laser microsurgery].
abstract: The aim of this study was estimation the long term results of CO2 laser therapy in laryngeal cancer. 36 patients with early glottic cancer-T1 and T2 were treated with CO2 laser microsurgery in 1990-1992. The control laryngological, phoniatric and laryngovideostroboscopic examinations were conducted from six to thirty months after the operation. The next controls were done within three years and then after eight to ten years from microsurgery. The local recurrence was observed only during the first control in seven cases--19%. Four patients underwent total laryngectomy after several laser microsurgery, two were treated only with CO2 laser and one had CO-therapy. The better quality of voice was observed during following control examinations. A scar with smooth surface and marge in 29 persons and a tendency to phonatory vibration of scar in 9 patients were noticed in laryngovideostroboscopy examination during the first control. Following examinations showed a progressive improvement of voice parameters.
