A follow-up study on 25 cases of larynx cancer treated by laryngofissure operation

In Japan, laryngofissure technique applied for the larynx cancer made its debut comparatively late, as compared with that in Europe and America. Namely, the laryngofissure was first used in the treatment of larynx cancer in 1931 by Prof. F. Tanaka and that was the first time this technique had ever been used in Japan, as far as in author's knowledge. This author had a good fortune to witness that first operation as his assistant.
