The Causes Nasal Obstruction
Descriptions of Deviated Septum, Enlarged Turbinates, Nasal Polyps, Sinusitis
An abnormality in nasal anatomy can lead to a blockage that can lead to snoring or a sinus infection. Below are descriptions of common nasal obstructions.
Deviated Septum (anatomical)
The nasal septum, composed of cartilage and bone, separates the two sides of the nose. A septum that is not in the middle of the nose is considered to be deviated. Deviated septums can block the flow of air and mucous in the nose.
Enlarged Turbinates (anatomical)
Nasal turbinates are small, shelf-like bony structures inside the nose that are covered with a mucous membrane. They function to warm and cleanse inhaled air before it reaches the lungs. When the mucous membrane on the turbinates becomes inflamed, the turbinates swell and cause an obstruction.
Nasal Polyps (non-anatomical)
A tissue growth in the sinus lining is known as a polyp. If the tissue protrudes into the nasal passage it can cause a blockage. Fifty percent of patients who have polyps also have allergies.
Sinus Disease or Sinusitis (non-anatomical)
A prolonged bacterial infection in the nasal passages can cause a nasal obstruction and a nasal obstruction can also cause an increase in the growth of bacteria. For more information about sinusitis, click here.
