What are common causes of nasal obstruction?
Common causes of nasal obstruction include a deviated nasal septum, nasal turbinate enlargement, and nasal polyps (benign growths.) Deviated nasal septum: The midline of the nose consists of a cartilage and bony nasal septum that separates the two sides of the nasal cavity. A deviation or bend in this structure can be present at birth or can occur following a nasal fracture. The obstruction caused by such a deviation can be corrected by surgically straightening the septum, called a septoplasty. A septoplasty is a commonly performed outpatient surgery done through incisions within the nasal cavity, removing the obstructing portion of bone and cartilage. Nasal turbinate enlargement: The nasal turbinates are three bony and soft-tissue structures lining the sides of the nasal cavity. As part of the normal nasal cycle, the turbinates alternately swell and enlarge. In some persons, the turbinates can be excessively large, resulting in significant nasal obstruction.
