Septoplasty is a surgery performed to correct a deviated (or crooked) septum. The septum is the piece of cartilage that separates one side of the nose from the other. Normally, the septum is straight. When it is crooked, it is termed a deviated septum. A deviated septum can block the nasal passage and contribute to symptoms of nasal obstruction.
Correction of a deviated septum with a septoplasy involves making an incision on the inside of the nose. The skin covering the septum is lifted off the cartilage and the crooked portion is either removed or reshaped to make the breathing passages more open.
A septoplasty does not change the shape of the nose and is therefore considered a functional procedure as opposed to a cosmetic procedure. As such, it is a procedure (as well as facility fees and anesthesia costs) that insurance should pay for. Verification of benefits and prior authorization before surgery should be obtained. For patients without insurance, the surgeon's fee for a septoplasty can range between $1000 and $2000.
