The results of therapy and rehabilitation of the target and control groups of patients with laryngeal cancer, each consisting of 70 people, demonstrated that the method of reconstructive subtotal resection of the larynx as compared to its extirpation was efficient and advantageous in medical, social and economic terms. The advantages of the modified method were verified clinically and statistically. In the target group every other patient and in the control group only one out of four patients regained their normal work capacity. The expenses for research and development paid off within a year.
