Abstract
1. Vertical Partial Laryngectomy (VPL): Our indications of VPL are in principle T1 and T2 glottic carcinomas. But most of them are considered to be curative by radiation therapy. For that reason the patients treated by VPL initially were only 5% of all T1 and T2 glottic carcinomas. On the other hand VPL for salvage of the radiation failures has been increased, because of the extended indication of irradiation for more advanced glottic carcinomas. Some postoperative complications are atrophy, fibrosis, and loss of the reconstructed soft tissues, which may yield severe hoarseness. The chondritis of the thyroid cartilage was found in two irradiated patients, one of them required total laryngectomy due to necrosis of the cartilage. 2. Horizontal Partial Laryngectomy (HPL): Our indications of HPL are in principle T1 and a part of T2 and T3 supraglottic carcinomas. It is mandatory to evaluate the exact deep invasion with CT scan, and to take into account of the patient's age and systemic conditions. One of the most serious postoperative complications is aspiration. It took a long period for some patients to swallow without aspiration who required wider resection in primary lesions or the combination of neck dissections. Decanulation was retarded for the patients received bilateral neck dissections, because of the persistent edema of the mucosa on arytenoid region.
