What is Nasal Obstruction?
Nasal obstructions are blockages of the nasal cavity that impede airflow in and out of the nose. Either one or both nostrils may be affected. Most nasal obstructions are temporary, caused by colds, allergies, sinus infections, or medications, while others require medical intervention.
Nasal Obstruction Symptoms:
- Chronic nasal congestion, or stuffiness
- Persistent nasal blockage or obstruction
- Difficulty breathing through nose
- Difficulty sleeping, snoring, and fatigue
- Inability to get enough air during activities
What causes nasal airway obstruction?
Even slight narrowing of the nasal valve can lead to significant reduction in airflow.26,27,28 Structural blockages in three areas are common:
- Septum: The cartilage wall between the nostrils can bend and block the nasal passage.
- Turbinates: Ridges of bone and tissue inside the nose can limit airflow when enlarged.
- Lateral (side) wall: Weak or excessively flexible upper/lower cartilage in the outer nasal wall may cause it to collapse inward when a person inhales.
The most common conditions to impact patients are septal deviation, turbinate hypertrophy, and nasal valve collapse. Lateral wall collapse may equal or even exceed septal deviation as the prime cause of nasal airway obstruction
