Orthognathic surgery also is known as corrective jaw surgery or simply jaw surgery and is performed to correct any sort of dislocation of the jaw that may result in affecting the physical appearance or the functioning. It is used to correct defects that occur due to TMJ disorders, orthodontic problems or problems due to sleep apnea and the ones which cannot be easily cured with braces. During the orthognathic surgery, the bone is cut, realigned or modified to correct the defect or any structural deformity. About 5% of the general population gets this done to correct jaw issues like difficulty chewing, difficulty swallowing, excessive wear of the teeth and deformities like maxillary prognathisms, mandibular prognathisms, etc. You can consider any of the maxillofacial surgeons in Mumbai, Delhi, Bangalore, etc for the fact that it is effective when it comes to correct a dentofacial deformity.
