Abstract:
Cystic fibrosis (CF) is a genetic disease caused by mutations in the cystic fibrosis transmembrane conductance regulator (CFTR) gene. The CFTR channel is responsible for the transport of the anions (chloride and bicarbonate) across airway epithelia. Patients with CF have thick mucus, disrupted mucociliary transport, and chronic bacterial infections in the upper and lower airways. In this article, the pathophysiology of CFTR dysfunction and its impact on the united airway are reviewed as well as the treatment strategies for patients with chronic rhinosinusitis-related CF and acquired CFTR dysfunction.

Cystic Fibrosis: Pathogenesis
CF is primarily caused by a genetic mutation in a chromosome 7 gene coding for the cystic fibrosis transmembrane conductance regulator (CFTR) protein. The most common gene mutation leading to CF is the ΔF508 mutation,...

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...
