Abstract

When thyroid carcinoma invades the larynx or trachea, the proper treatment is needed because of significant morbidity and mortality due to airway obstruction. Hemoptysis and dyspnea are the result of intraluminal extension of the tumor and call for immediate investigation with endoscopic examination and CT. If the thyroid carcinoma with extracapsular spread invades only outer perichondrium of the tracheal or laryngeal cartilage, the shaving operation would be sufficient, but if the tumor invades the cartilage or if there is intraluminal invasion, it is mandatory to remove partial or total part of some aerodigestive tract structures. We retrospectively analyzed 14 surgical cases of the thyroid cancer with laryngotracheal invasion(12 papillary carcinomas and 2 anaplastic carcinomas) at the Department of Otorhinolaryngology-Head and Neck Surgery, Seoul National University Hospital. The analysis was focused on clinical manifestation, pathologic findings, types of management and results. Survival result was not adequately analyzed due to some recently operated cases.
