Septoplasty is a corrective surgical procedure done to straighten the nasal septum - the partition between the two nasal cavities. The septum should run down the center of the nose. When it deviates into one of the cavities, it narrows that cavity and impedes airflow. The inferior turbinate on the opposite side undergoes something called Compensatory hypertrophy. Turbinate reduction is also involved in enlarging the cavity. Since the deviation is a result of a cartilage and/or bone surplus, the procedure usually involves an excision of a portion of those tissues. Under anesthesia an incision is made in the lining of the septum to reach the cartilage targeted in the operation. Often an "L" strut of cartilage in the dorsal and caudal areas (1cm width or more) is preserved for structural support. After excess cartilage and bone have been taken out, the septum is stabilized with small plastic tubes, splints, or sutures. Large swelling and bruising can be expected. The nasal cavities may or may not be packed, and a piece of gauze is taped underneath the nose to absorb blood. Inner nasal packing may be removed only after excessive bleeding stops. After 1 to 2 weeks, patients are allowed to blow their nose normally.
