Orthognathic surgery is a unique endeavor in facial surgery: a patient's appearance and occlusal function can be improved significantly, impacting the patient's sense of self and well-being. Successful outcomes in modern orthognathic surgery rely on close collaboration between the surgeon and the orthodontist across all stages of treatment, from preoperative planning to finalization of teeth bite / occlusion.Orthognathic surgery is the mainstay treatment to reposition the maxilla, mandible, or chin patients who are too old for growth modification (before adulthood) and for dentofacial conditions that are too severe for either surgical or orthodontic camouflage / treatment. The adjunctive procedures include an osseous versus alloplastic genioplasty, lipoinjection or suction lipectomy,
