Before surgery, the doctor may use a thin, lighted instrument (endoscope) to look at the nasal passage behind the deviated septum.
The procedure usually involves a judicious excision/realignment of a portion of the bone and/or cartilage in the nasal cavity. Under general or local anesthesia, the surgeon works through the nostrils, making an incision in the lining of the septum to reach the cartilage targeted in the operation. Sufficient cartilage is preserved for structural support. After the septum is straightened, it may then be stabilized temporarily with small plastic tubes, splints, or sutures internally.
