Abstract:
A case of tracheobronchopathia osteochondroplastica (TO) was diagnosed in a 53-year-old man, who presented with prolonged cough and recurrent respiratory tract infection. Bronchoscopy revealed exostosis over the anterolateral wall of trachea and main bronchi sparing the posterior membranous wall. The endobronchial biopsy subsequently revealed ossification of the cartilage. To date, the aetiology of this condition remains unknown, and treatment is mainly symptomatic, emphasizing on timely management of recurrent respiratory infections. Bronchoscopy or surgical intervention is usually reserved for symptomatic patients with severe airway narrowing and airflow obstruction.

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...

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...
