Inferior Turbinate Hypertrophy

Turbinates are bony structures inside your nose covered by mucous membranes. They act as radiators in your nose by adding warm moist heat to the air that passes as we breathe. The turbinates are very susceptable to allergy and dust irritation.

There are three pairs of turbinates:

  • inferior turbinates
  • middle turbinates
  • superior turbinates

Causes of hypertrophied turbinates

The mucous membrane that covers the turbinates can shrink or swell in response to changes in blood flow. Things that alter blood flow such as lying down, certain foods, allergies, medications, hormones, and infections can affect blood flow and therefore cause swelling of the turbinates.

When the turbinates become enlarged, they block breathing and make you feel congested. The inferior turbinates, the largest pair, are often the source of breathing problems. When the inferior turbinates become enlarged it is referred to as inferior turbinate hypertrophy.

Special Considerations:

Septal Deviations - In patients with a septal deviation is it not uncommon for both sides of the nose to be blocked. A common scenario would be that one side of the nose is blocked from the deviated septum and on the other from permanent inferior turbinate hypertrophy.

Allergies - Allergies can cause swelling, often leading to permentant turbinate hypertrophy.

Colds and Infections - Most of the time when you are congested due to a cold or infection the turbinates will enlarge and then return to their normal size. However, in some instances such as chronic sinusitis the turbinate hypertrophy may be permanent.
