Oral surgery is clinically known as oral and maxillofacial surgery, and the specialty focuses on the treatment of oral-related diseases through surgical treatment. Oral surgery belongs to a medical subspecialty of dentistry, which is a developing discipline. Various dental extractions, pre-prosthetic surgery, lip and tongue lengthening, maxillofacial trauma, deformities, tumors, and inflammatory diseases are all diseases treated by oral surgery. The oral surgery clinic mainly deals with tooth extraction, pericoronitis of wisdom teeth, pediatric dental tumors, short labial and lingual tethering, small swellings or small cysts of the labial and lingual gums, etc. Problems such as soft and hard tissue trauma and jaw fractures of the maxillofacial region can be treated under local and general anesthesia depending on the location and size. The dislocated fracture fragments are repositioned and fixed with small titanium plates, and the soft tissues are sutured to close the wounds. Small foci of infection can be treated under outpatient local anesthesia by incision to drain the pus and irrigation. When there is a large tissue gap infection with fever and other symptoms or extensive osteomyelitis of the jaws, general anesthesia is required for surgical treatment and systemic medication. There are also many types of tumors in the maxillofacial area. Tumors may occur in the lip, tongue, gums, palate, and parotid gland, and often require surgical excision depending on the nature of the tumor, and repair of the excised facial tissue at the same time. Mouth breathing, genetics, cleft lip and palate, etc. can cause facial deformities that affect aesthetics, and oral surgeons operate on different types to restore a beautiful appearance to the patient. Oral surgery sees a wide range of patients. Oral surgery has a close relationship with oral medicine, orthodontics and prosthodontics. Oral surgery treats diseases that are generally more dangerous and must be seen in a timely manner to avoid delays and aggravation of symptoms.
