Some patients may require jaw surgery after birth due to a congenital birth defect. Other patients may develop a need for the procedure after their physical development has shown that their jaws are misaligned, or are growing at different rates. This typically becomes clear during or following adolescence, and it may only be used as a last resort following orthodontic correction attempts, which often can correct dental problems but not larger jaw issues. The need for corrective jaw surgery may also be caused by facial trauma or disease.
