Mandibular fracture; Other names: Mandible fracture, fracture of the jaw: 3D computed tomographic image of a mandible fracture in two places. One is a displaced right angle fracture and the other is a left parasymphyseal fracture. Specialty: Oral & Maxillofacial Surgery: Symptoms
The Le Fort I osteotomy is a surgical procedure to realign the upper jaw ().This procedure is a type of orthognathic surgery that is primarily performed to fix deformities of the face and jaw, improve facial aesthetics, treat malocclusions (misaligned teeth), and treat certain medical conditions, such as obstructive sleep apnea.
A Le Fort I osteotomy surgically moves the upper jaw to correct misalignment and deformities. It is used in the treatment for several conditions, including skeletal class II malocclusion, cleft lip and cleft palate, vertical maxillary excess (VME) or deficiency, and some specific types of facial trauma, particularly those affecting the mid-face.
Commonly injured facial bones include the nasal bone (the nose), the maxilla (the bone that forms the upper jaw), and the mandible (the lower jaw). The mandible may be fractured at its symphysis, body, angle, ramus, and condyle. [4] The zygoma (cheekbone) and the frontal bone (forehead) are other sites for fractures. [13]
The Le Fort III fracture (transverse fracture) occurs at the level of the skull base, resulting in complete craniofacial separation of the midface from the base of the skull. [ 2 ] [ 3 ] The fracture line extends through the zygomatic arch , the pterygoid plates , the lateral and medial orbital walls , the nasal bones , and the nasal septum .
Orthognathic (literally "straight jaw") reconstructive surgery, orthognathic surgery, maxillomandibular advancement, surgical correction of facial asymmetry. soft and hard tissue trauma of the oral and maxillofacial region (jaw fractures, cheek bone fractures, nasal fractures, LeFort fracture, skull fractures and eye socket fractures).
Fracture of the maxilla: Le Fort fracture, zygomatic fracture, orbital blowout; Fracture of the mandible; Trauma injuries involving the alveolus can be complicated as it does not happen in isolation, very often presents along with other types of tooth tissue injuries.
