The maxilla is a paired bone that forms a significant portion of the midface. It articulates with the frontal, zygomatic, palatine bone, and sphenoid bones. The Le Fort I segment, the portion of the maxilla mobilized during the osteotomy, receives its blood supply primarily from the ascending palatine artery (a branch of the facial artery) and the anterior branch of the ascending pharyngeal ...
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.
The Le Fort II fracture (pyramidal fracture) includes a fracture line from one of the lateral vertical buttresses across the maxillary bone, extending into the inferior orbital rim and crossing the midline (either through the nasal root or nasal bones). [5] The defining feature of this fracture pattern is involvement of the inferior orbital rim ...
Fractures with displacement require surgery consisting of fracture reduction with miniplates, microplates and screws. Gillie's approach is used for depressed zygomatic fractures. [5] The prognosis of tripod fractures is generally good. In some cases there may be persistent post-surgical facial asymmetry, which can require further treatment. [6]
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]
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 ...
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.
In vertebrates, the maxilla (pl.: maxillae / m æ k ˈ s ɪ l iː /) [2] is the upper fixed (not fixed in Neopterygii) bone of the jaw formed from the fusion of two maxillary bones. In humans, the upper jaw includes the hard palate in the front of the mouth. [3] [4] The two maxillary bones are fused at the intermaxillary suture, forming the ...
