What Is a Sinus Infection?
Reviewed: Dr. Gromatzky
6. Deviated Septum
The septum is the name of the bony ridge in your nose, and it separates the two nasal cavities from each other. A deviated septum is when the septum is not straight, and this can cause the nasal passages to become blocked. A deviated septum is sometimes something people are born with, while it is often caused by an injury.
This blocking of the nasal passages can also mean that the ducts coming from the sinuses can also be blocked. A blockage of these ducts increases the risk of a sinus infection developing. Other conditions that block these ducts can also result in a sinus infection.
