The 933 patients (a total of 1066 operative procedures),552 males and 381 females, who underwent endolaryngeal microsurgery at the Department of Otolaryngology of Kinki University Hospital between 1975 and 1990 were reviewed retrospectively. They ranged in age from 2 to 83, most of them being between the age of 30 and 69. The incidence was higher for males than for females in the age group of 40 years and over. The 67 patients (7.2%) were above 70 years old. Vocal fold nodule, polyp and Reinke's edema were most frequently treated i.e., in 57.4% of the total cases, malignancies in the larynx and the adjacent region (laryngeal cancer in the majority) in 17.4%. Endolaryngeal microsurgery was adapted most frequently to the cases for repairing phonatory function, and for examining malignant pathologies in the larynx. Laryngeal cancer was most common in 51% of the patients above 70 years old, and accounted for 29% of the 124 patients with cancer in the larynx. In the 36 patients (a total of 46 operative procedures), the various lesions (glottic cancer in the majority) without vocal fold nodule, polyp and Reinke's edema were treated by CO2laser in the endolaryngeal microsurgery. Three methods of general anesthesia were employed for surgery: endotracheal intubation in 75%, neuroleptanalgesia in 23% and high frequency jet ventilation in 2%. The pharynx and/or oral cavity was easily damaged by the suspension laryngoscope. The incidence of damage was higher in the cases in which insertion of the laryngoscope was difficult.
