The septum is the wall of bone and cartilage that divides your nose into two separate nostrils. A deviated septum occurs when your septum is moved to one side of your nose. Septoplasty surgery is performed under general anesthesia. Through an incision made inside the nostril, the tissue (mucosa) covering the septum is lifted up to allow the surgeon to see the bone and cartilage directly. The operation usually takes 1 to 2 hours.
