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.
Caldwell-Luc surgery, Caldwell-Luc operation, also known as Caldwell-Luc antrostomy, and Radical antrostomy, is an operation to remove irreversibly damaged mucosa of the maxillary sinus. It is done when maxillary sinusitis is not cured by medication or other non-invasive technique. The approach is mainly from the anterior wall of the maxilla bone.
Between the two surgeries, a patient's constricted maxillary arch is expanded with the rapid maxillary expander device placed in the maxilla. For the first surgery, under local anaesthesia and iv sedation or general anesthesia, a patient first goes through Le Fort fracture of skull without the downfracture of maxilla. The oral surgeon also ...
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 .
The procedure, which is strictly used for a mandibular (jaw) deformity and mobilization, has advanced from similar, very effective procedures performed since 1985. The original mandible and maxilla osteotomy procedure still remains almost unchanged, as it is the simplest and still the most effective for dentofacial deformity correction.
In some instances, maxillary fractures are a combination of two or three Le Fort types. Although this system of classification is considered somewhat simplistic today, it is still widely used in oral and maxillofacial surgery. It was modified by Robert D Marciani in 1993 to more precisely define Le Fort fracture patterns. [6]
In the United States, oral and maxillofacial surgery is a recognized surgical specialty, formally designated as a dental specialty. A professional dental degree is required, [5] a qualification in medicine may be undertaken optionally during residency training. In this respect, oral and maxillofacial surgery is sui generis among surgical ...
Craniofacial surgery is a surgical subspecialty that deals with congenital and acquired deformities of the head, skull, face, neck, jaws and associated structures. Although craniofacial treatment often involves manipulation of bone, craniofacial surgery is not tissue-specific; craniofacial surgeons deal with bone, skin, nerve, muscle, teeth ...
