Swollen, Nasal Turbinates (Hypertrophy)
Turbinates (Hypertrophy) – About
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 susceptible 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.
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 permanent 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.
Turbinates (Hypertrophy) – Diagnosis
Diagnosis of turbinate hypertrophy can usually be made on your first visit.
After taking your history and performing an exam we will use an endoscope, a small telescope with a light on one end and an eyepiece at the other, to examine the inside of your nose.
A CT scan may also be used to show inferior turbinate hypertrophy.
Turbinates (Hypertrophy) – Treatment
Nasal steroids, nasal antihistamines and decongestants can be used to treat inferior turbinate hypertrophy. These medications help to reduce the swelling and improve nasal breathing. If you do not respond to medications, it may be necessary to perform a simple surgery to reduce the size of your inferior turbinates.
The surgeons at ENT Center of Utah usually use a small suction/shaver beneath the membranes (submucous resection) to remove tissue and some bone inside the inferior turbinate or we may surgically resect the anterior portion of the turbinate. The the turbinate is also “outfractured” to create a better lateral position and improve breathing. This surgery is occasionally performed by it self, but is often combined with a septoplasty to completely address nasal obstruction.
