Nasal Obstruction
What is
Nasal airway obstruction?
Nasal airway obstruction is a condition in which the nasal passages are blocked and prevent a normal or comfortable amount of air from passing through the nose. Nasal airway obstruction affects more than 20 million Americans1 and can occur because of a structural abnormality in the nose or because of inflammation and swelling of the nasal passages. With nasal breathing delivering approximately 70% of airflow to the lungs,2 any blockage that limits airflow can cause significant quality-of-life consequences.3
What causes
Nasal Airway Obstruction?
Even a slight narrowing of the nasal valve can lead to significant reduction in airflow.4-6 Structural blockages in 3 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.

Does your breathing improve when you pull on your cheek to hold your nostril to the side?
If yes, talk to your doctor about options to support your lateral nasal cartilage, which may include the LATERA® implant.
Is lateral wall collapse contributing to my
Nasal airway obstruction?
To determine whether the lateral wall is contributing to your nasal airway obstruction, a clinician may use a number of approaches. Examples include:
- A simple breathing test called the Cottle test (see animation)
- Use of nasal strips during normal activity and sleep
If your symptoms improve from either of the above, you may benefit from support of the lateral nasal wall.

Is my quality of life affected by
Nasal Airway Obstruction?
The Nasal Obstruction Symptom Evaluation (NOSE) survey9 is an assessment tool designed to capture how your breathing symptoms are affecting your quality of life. It is a simple 5-question survey and uses a 20-point scale to capture breathing symptoms, with higher scores indicating more severe symptoms than lower scores. Take the NOSE survey below and print or email your results to discuss with your doctor.
