Tracheobronchial anomalies

are relatively rare. Congenital esophagotracheal and esophagobronchial

fistulae are occasionally seen, and cases of cervicotracheal fistulae

have been reported. Congenital webs and diverticula of the trachea are

cited infrequently. Laryngoptosis and deviation of the trachea may be

congenital. Substernal goitre, aneurysm, malignant growths, and

various mediastinal adenopathies may displace the trachea from its

normal course. The emphysematous chest fixed in the deep voluntary

inspiratory position produces in some cases an elevation of the

superior thoracic aperture simulating laryngoptosis (Bibliography r,

pp. 468, 594).
