Abstract
The author experienced a case of delayed decannulation. A man 20 years old complained of dyspnea 2 weeks after tracheotomy which had been performed soon after the traffic accident in February, 1959. The glottis was filled with granulation tissue, which was removed by laryngofissure. The T-formed tube was inserted but soon followed by dyspnea.
No treatment tried after that was successful in decannulation.
4 years later (March, 1963), the author improved the T-formed tube, which was combined with a straight vinyl-tube, and fixed it in the trachea. The patient at present does not complain of any disorders except cough and dysphonia.
