Abstract
Endolaryngeal microscopic laryngosurgery (microlaryngosurgery) using a direct laryngoscope is the preferred surgical method for treating laryngeal lesions under general anesthesia. However, this method does not provide a wide-angle view of the larynx and does not allow detailed observations of the ventricle and subglottis of the laryngeal cavity, resulting in blind areas. Video-assisted endoscopic laryngosurgery using a direct laryngoscope and a long transurethral rigid endoscope was therefore utilized to allow clear observations and complete resection of laryngeal lesions in these blind areas. This endoscopic surgical technique is introduced, and clinical cases are presented.
