Hand surgery is a field that helps patients with a variety of health issues involving the hands. This can include both surgical and non-surgical care. These doctors treat conditions that present not only in the hands but also the arms. These conditions may include infections, abrasions, injuries, and arthritis. Surgeons trained in orthopedic surgery, general surgery, and even plastic surgery are all qualified to perform surgeries on the hands or provide other treatment for this area.

Oral and Maxillofacial Surgery is a medical subspecialty that can help treat diseases and disorders of the face, head, neck, and soft tissues of the jaw. It can include surgical and non-surgical interventions for issues of this sort. While it is generally considered a subspecialty of medicine, it is also closely related to dentistry. In fact, some oral and maxillofacial surgeons may even work with dental problems or in conjunction with dentists to solve oral and dental complications.
