Tracheal Changes after Tracheostomy

Tracheal stenosis is a rare but serious complication of tracheostomy. The frequency of manifest stenosis with interference of respiratory function was 2% in 259 surviving cases of tracheostomy at our hospital 1960–1964. In order to investigate if minor degree of stenosis develope after tracheostomy without being noticed, X-ray examination has been done on patients who have had tracheostomy at the hospital during 1965. The results are given and discussed.
