A deviated septum is a common deformity in the nasal cavity. Experts estimate 70 to 80% of people have a deviated septum. For some, symptoms are barely noticeable, while others experience chronic breathing difficulties and discomfort. There are treatments available for a deviated septum regardless of severity. Some are simple and non-invasive, but surgery is also an option for more problematic cases.
The nasal septum is the thin wall between nasal passages. It extends from the nostrils to the back of the nose and consists of cartilage and bone. This wall is usually straight, but it may deviate away from the middle. Sometimes, the wall is just slightly off center, making one nostril a little larger than the other but not causing any noticeable problems. On the other hand, this defect can also be so severe as to significantly restrict airflow through the nasal passages.
