Nasal obstruction refers to some blockage of the nose or nasal cavity and can be caused by a wide variety of problems. There are several common causes of nasal obstruction:
- Inferior turbinate hypertrophy
On the inside of the nose there are normal bony structures called turbinates. They are covered by a large amount of spongy mucosa (the pink lining inside the nose). The turbinates are very susceptible to allergy and dust irritation. If they become swollen, it can be difficult to breathe through the nose.
- Deviated nasal septum
The septum is the structure separating the nostrils inside the nose. A deviated nasal septum is a crooked septum. Symptoms may include difficulty breathing through the nose (especially on one side), and a runny nose. A deviated nasal septum may be caused by trauma to the nose.
- Foreign bodies in the nose
- Large adenoids – which block the back of the nose
- Swelling of the lining of the nose from allergies
- Choanal atresia
This is a congenital (present at birth) condition that is a narrowing or blockage of the nasal airway by tissue.
- Pyriform aperture stenosis
