先端を閉鎖した特製Ｔチューブによる声門下狭窄の治験例

Abstract

A two-yeas-old boy with subglottic cicatricious stenosis who underwent treatment with the use of specially designed T-tube was reported. He was admitted to our hospital complaining of difficulty in decanulation. Direct laryngoscopy revealed that his subglottis was stenotic and, in addition, that there was a posterior glottic stenosis. When he was five years old he underwent open reduction surgery. Laryngofissure was performed, and the cicatricious tissue was removed. After a posterior cn coid split was done, followed by an autograft of his rib cartilage, his cheek mucosa was transplanted. Three days after the operation, a specially designed T-tube was anchored. The top and of this silicone T-tube was convex-shaped and closed, and its size was pre-determined in consideration of his larynx and trachea. With the use of this T-tube, no granulation was observed, and no further stenosis developed, resulting in a good clinical outcome. This new type of T-tube seems to be useful and effective for the treatment of subglottic stenosis.
