Deviated septum surgery, also known as septoplasty, involves making an incision to separate cartilage and bone from nasal mucosa, or soft tissues, lining the septum and nasal passages, according to WebMD. Surgeons trim and straighten bent cartilage and replace mucosa over the bone and cartilage.
Patients with damaged portions of the septum may require the removal of the deviated portions of the septum during surgery, according to the American Academy of Otolaryngology-Head and Neck Surgery. Surgeons may also readjust the damaged deviated portions of the septum and reinsert them into the nose during surgery.
Prior to surgery, patients are given local or general anesthesia that lasts for approximately 60 to 90 minutes, the length of the operation, according to WebMD. The surgeon may also use an endoscope to view the shape of the septum and nasal passages before beginning the operation.
Following surgery for a deviated septum, surgeons insert nasal packing into the nasal cavities to prevent excessive bleeding, explains the American Academy of Otolaryngology-Head and Neck Surgery.
Surgery for a deviated septum is performed to treat inflammation and bleeding or to treat chronic sinusitis or sleep apnea, explains WebMD. Nasal polyps may also be removed during the surgery to help realign the septum. People with breathing problems or chronic snoring often benefit from deviated septum surgery.
