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).
