orthognathic surgery
Pronunciation: or-thog-NATH-ik
Corrective jaw surgery designed to realign the jaws and teeth to improve function and facial aesthetics.
Full Definition
Orthognathic surgery encompasses surgical procedures designed to correct dentofacial deformities involving malposition or malformation of the maxilla, mandible, or both. These procedures address functional problems such as difficulty chewing, speaking, or breathing, as well as aesthetic concerns related to facial proportion and symmetry. Common procedures include maxillary and mandibular osteotomies, genioplasty, and distraction osteogenesis. Treatment typically requires close collaboration between oral surgeons and orthodontists.
Usage
Usage note: Distinguished from general maxillofacial surgery by its specific focus on jaw alignment and dental occlusion.
