What is deviated septum?
A deviated septum often does not have any symptoms, but some symptoms include difficulty breathing through the nose, nasal congestion, sinus infections, nosebleeds, sleep problems, headache, and postnasal drip.
The thin wall between the nostrils is made of cartilage and bone and is called the septum. The septum is made up of bone and cartilage. When this cartilage or bone is off-center (deviated to one side) or crooked, it is referred to as a deviated septum.
- A deviated septum may be present at birth, may become crooked during growth, or maybe caused by injury to the nose and face.
- A deviated septum often does not have any symptoms, but some symptoms include difficulty breathing through the nose, nasal congestion, sinus infections, nosebleeds, sleep problems, headache, and postnasal drip.

How is deviated septum diagnosed?
Your health care professional can diagnose a deviated septum during the physical examination. Usually a bright light and an instrument that can help visualize the nasal septum by opening the nostril (nasal speculum) will help make the correct diagnosis. Some deviated septums are deep in the nose and may require further evaluation in the office with a small telescope or endoscope. Imaging may occasionally be done with a CT scan to view the extent and other associated to findings, but this is not often done.
How is deviated septum treated?
A deviated septum is an extremely common condition and many people with a deviated septum do not need treatment.
Some symptoms such as a stuffy nose or postnasal drip may be alleviated with medication, including decongestants, antihistamines, or nasal sprays. In many cases, medications are tried before surgery is recommended.
If a person has a deviated septum and it causes breathing problems or sleep apnea and snoring, surgery may be recommended to repair the septum. Surgery to fix a deviated septum is called
- a septoplasty,
- submucous resection of the septum, or
- septal reconstruction.
