An attempt was made to develop a new method of microsurgery of the larynx. A newly designed laryngostroboscope suitable for our purpose was employed in our new method. The vibratory pattern was stroboscopically examined through the operating microscope throughout the operative procedure while the patients who were able to phonate due to neuroleptanalgesia were asked to do so. Thus, the determination of the completion time of the operation was obtained mainly by the observation of stroboscopic vibratory patterns of the vocal cords.

Since the beginning of 1972, this stroboscopic microsurgery of the larynx has been satisfactorily employed in more than 200 cases of various kinds of laryngeal lesions. As a result, a remarkable improvement of the postoperative voice was observed by phonatory examinations as well as by audible estimation.
