Deviated Septum
The nasal septum is the wall that divides the right and left nasal cavities. When the septum is not straight, or is deviated, it may obstruct one side of your nasal breathing more than the other.
A deviated septum may cause other problems such as nosebleeds, congestion due to turbinate enlargement, recurrent sinus infections, nasal or sinus pain, and external changes to the nose.
Causes of a deviated septum are typically related to nasal trauma. The trauma may or may not be related to a nasal bone fracture which is often associated with more visible signs of swelling, bruising, and bleeding. The event may occur early in life with no memorable recollection by the patient.
In a smaller number of individuals, the septum may be congenitally deviated. This is often associated with other congenital abnormalities of the nose or lip, such as cleft lip and palate. Significant trauma during the birthing process may also contribute congenitally deviated septum.
