Abstract:
We report a case of bronchiectasis in a 26-year-old man associated with the following congenital abnormalities: deafness, purulent bronchorrhea, nasal polyps, dysmorphic physical pattern and chronic sinusitis. Situs inversus was absent. A sampling was performed on the posterior nasal mucous membrane and displayed structural ciliary abnormality: a deficiency of the intern dynein-arm. The patient's bother was affected and had similar features: congenital bronchiectasis, deafness, mental deficiency and sinusitis. Young's syndrome was relevant in this case. Hereditary ciliary dyskinesia should be considered in adults with bronchiectasis together with rhinologic and alimentary canal disorders. Nasal biopsies are safe and allow cilia examination.

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...
