Maxillary orthognathic surgery, or maxillary advancement, corrects skeletal and dental irregularities in the upper jaw. This procedure, performed under general anesthesia, repositions the maxilla for improved alignment with the lower jaw and facial structures. It may involve moving the maxilla forward, backward, or laterally, using plates and screws for stabilization. Recovery includes managing swelling and discomfort, dietary adjustments, and follow-up visits to ensure proper healing and occlusion. Overall, it significantly enhances both function and aesthetics, improving patients' quality of life.
