The nasal septum is the wall between the nostrils that separates the two nasal passages. It supports the nose and directs airflow. The septum is made of thin bone in the back and cartilage in the front. A deviated septum occurs when the cartilage or bone is not straight. A crooked septum can make breathing difficult. The condition also can lead to snoring and sleep apnea.
The septum can be deviated at birth (congenital) or because of injury, such as a broken nose. It also may bend to one side or the other as a result of aging. Very few people have a perfectly straight septum. Septoplasty generally is necessary only when breathing problems or snoring do not get better without surgery.
Surgery to straighten the septum is called septoplasty, submucous resection of the septum, or septal reconstruction. The surgery may be done along with other procedures to treat chronic sinusitis, inflammation, or bleeding, or to correct sleep apnea. Septoplasty also may be done to allow access into the nose to remove nasal polyps. For more information on surgery to treat chronic sinusitis, see the topic Sinusitis.
Before surgery, the doctor may use a thin, lighted instrument (endoscope) to look at your nasal passages and to see the shape of your septum. In some cases, the endoscope may be used during surgery. You will receive local or general anesthesia for the 60- to 90-minute operation, which is usually done in an outpatient surgery center.
The septum and nasal passages are lined with a layer of soft tissue called the nasal mucosa. To repair the septum, the surgeon works through the nostrils, making an incision to separate the mucosa from the underlying cartilage and bone. The doctor trims or straightens the bent cartilage and then replaces the mucosa over the cartilage and bone.
