One hundred and twenty-six patients with laryngeal carcinomas were clinically analyzed who visited our clinic from September 1973 to August 1982 of there 118 were followed retrospectively.<br>The results in this study were as follows;<br>1) The three- and five-year survival rates were 77% and 71%, respectively.<br>2) There were 95 cases of the glottic type, 25 of the supraglottic, and 6 cases of the subglottic.<br>3) According to the classification of stage, there were 65 patients in stage I or II. Thirtysix of them have been well controlled by radiotherapy only without 2 patients. Eighteen patients were treated with reconstruction after partial laryngectomy and postoperative irradiation. The other 11 were treated with total laryngectomy. The crude survival rates for each of them were calculated to be 89%, 100% and 82%, respectively. In 53 patients at stages III and IV, 17 were treated with total laryngectomy and preand post-operative irradiation. The crude survival rate for them was 94%.<br>4) In 36 patients who received radiation and are classified to be T1 and T2, 2 had recurrence, but 17 treated with reconstruction after partial laryngectomy maintained comfortable conditions for speech and respiration without tumor recurrence. Mainly discussed how to choose the best way of treatment for glottic T1 and T2, i. e. weather to select initial radiation or reconstruction after partial laryngectomy.<br>5) Our data showed that neck dissection might be necessary for good results even when there is no evidence of neck metastasis.
