Oral and Maxillofacial Surgery is a surgical specialty focusing on reconstructive surgery of the face, facial trauma surgery, the oral cavity, head and neck, mouth, and jaws, as well as facial cosmetic surgery. Oral and maxillofacial surgeons are trained to recognize and treat a wide spectrum of diseases, injuries and defects in the head, neck, face, jaws and the hard and soft tissues of the oral and maxillofacial region. They are trained to treat problems such as facial deformity and misaligned jaws, tumors and cysts of the jaw, head and neck cancer, skin cancer, trauma surgery and some perform dental implant surgery and the extraction of wisdom teeth. In the United States, oral and maxillofacial surgeons are trained to administer general anesthesia and deep sedation and are licensed to do so in a hospital or office setting.
