The larynx has very important roles, as the organ for respiration, phonation and protection of the lower air tract. A total resection of the larynx, therefore, affects the quality of life of the patient after the operation. Hereby, we emphasize that it is very important to preserve the laryngeal function as much as possible. For this purpose, every laryngologist makes a pains-taking effort to find the cancer of the larynx as early as possible. Recently, an endoscopic videostroboscopy using a flexible fiberscope has been greatly developed and applied for daily clinical use. As the laryngeal cancer is found at so early stage, surgeons come to have a better opinion for a functional surgery. The functional surgeries we have performed in our clinic are as follows; - laser surgery under microlaryngoscopy - cordectomy through laryngofissure - vertical partial laryngectomy. The indication for each was investigated in retrospect. We have summarized up as follows; 1. The laser surgery should be done for the case with carcinoma confined to the membranous part of the vocal fold without invasion to the anterior commissure. 2. The cordectomy through laryngofissure should be done for the case with a small invasion to the ventricle (without invasion to the false vocal fold). 3. The partial laryngectomy should be done for the case with an apparent invasion to the ventricle (without invasion to the false vocal fold).
