Orthognathic surgery, also known as corrective jaw surgery, is a procedure to correct severe jaw irregularities or skeletal discrepancies that cannot be addressed with orthodontic treatment alone. It involves repositioning the upper jaw (maxilla), lower jaw (mandible), or both to improve facial symmetry, bite function, and overall oral health. Orthognathic surgery may be recommended for conditions like severe malocclusions, jaw misalignments, sleep apnea, or facial trauma. Treatment begins with comprehensive planning, including dental and skeletal assessments, and may involve pre-surgical orthodontic preparation. The surgery is performed in a hospital setting and often requires a recovery period, but it can provide significant functional and aesthetic benefits.
