Abstract
A 31 years old male who had post traumatic stenosis of the trachea associated with laryngeal nerve paralysis was treated by end-to-end anastomosis of the trachea In this procedure the thyro-hyoid muscles and pharyngoconstrictos were cut and the lower part of the trachea was free from the superior mediastinum before the stenotic portion of the trachea was removed and end-to-end anastomosis of the trachea was performed.
Post-operatively no swallowing difficulty was observed even under cineradiography, and the air way was still patent 2 years and 6 months after the surgery.
Aphonia was present in the early postoperative stage, but vocal function improved gradually and considerably, and at present, we can observe a good motility of the false vocal cords and the left vocal cord.
Improvement of phonetic function has been proved on cineradiogram, radiogram and electromyogram, and according to the results of these observations, the author considered the regeneration of the recurrent nerve.
