Nasal Obstruction Causes
Narrowing of the nasal valve may be caused by an enlargement of any of the three primary structures, decreasing the overall nasal airway area.
Nasal Airway Obstruction
The Septum, Lateral Wall, and Turbinates form a triangular area known as the Nasal Valve. If any of these tissues enlarge, nasal airway size is reduced, causing lower airflow.
- The Septum is the narrow ridge of bone and tissue between the two nostrils.
- The Turbinates are fingers of tissue that direct and warm air as it enters the nasal cavity.
- The Lateral Wall is the side tissue that forms the outer wall of the nose.
