Abstract:
Tracheal-bronchus is an aberrant bronchus arising from the lateral tracheal wall, superior to the carina. A "False-carina" can be classified as a sub-type. This clinical entity will be defined and the clinical presentation, diagnosis and management of five patients with variations of the anatomical definition of a False-carina, identified at our institution, will be reviewed. Congenital bronchial abnormalities, including False-carina, have important implications in the overall management of the airway. Management can range from expectant in asymptomatic patients to surgical intervention in cases of recurrent respiratory infections. Awareness and understanding of this clinical entity allows for timely investigation, diagnosis and appropriate intervention.

The Bronchial Tree
The trachea, commonly known as the windpipe, is a tube that connects the larynx (voice box) to the bronchi. At a point called the carina, it bifurcates into two primary bronchi. The right primary bronchus is wider, shorter, and more vertical than the left primary...
Trachea
Anatomical Features:
Location: About half of the trachea is situated in the neck, anterior to the esophagus, and extends from the larynx (at the level of...

The Larynx
It is located between the pharynx and the trachea, acts as a passageway for air, and hosts several critical structures, such as the epiglottis, vocal cords, and glottis. The epiglottis acts as a gateway, guiding food to the...
