In LeFort III fractures exposure of the superior aspect of the lateral orbital wall and occasionally the zygomatic arch will require a brow incision and rarely a temporal approach through a hemicoronal incision will be used. The surgical management of LeFort fractures using internal fixation proceeds in a step wise fashion For true Le Fort III fractures, bilateral zygomaticofrontal fixation may suffice. However, more commonly, additional points of fixation are needed (eg, nasomaxillary, nasofrontal, inferior orbital rim, zygomatic arch). Use as few plates as possible to achieve fixation; excessive plating is not necessary A plate that is placed for the fixation of the fracture at the zygomaticomaxillary buttress is generally a larger plate because it is the point that will provide most stability to the Le Fort I fracture. The highest forces of mastication would be in this area. Depending on the fracture pattern an L-, T-, Y-plate or a straight plate may be used Classification. The commonly used classification is as follows: Le Fort type I. horizontal maxillary fracture, separating the teeth from the upper face. fracture line passes through the alveolar ridge, lateral nose and inferior wall of the maxillary sinus. Le Fort type II
Le Fort fracture; Le Fort I (red), II (blue), and III (green) fractures: A Le Fort fracture of the skull is a classic transfacial fracture of the midface, involving the maxillary bone and surrounding structures in either a horizontal, pyramidal or transverse direction. The hallmark of Lefort fractures is traumatic pterygomaxillary separation, which signifies fractures between the pterygoid. Lefort 3 Fracture. 1. 38yo M presents unconscious after motorcycle accident. Pt found 40yds from scene. Obvious facial trauma and left lower extremity trauma.

This is particularly applicable in fractures that are widely displaced, mobile, or unstable At this point, the occlusion and mandibular-maxillary fixation has been reestablished with intact spatial relationships to the skull base. This will assist in restoring the vertical facial height. The malar bones through the LeFort III level will need to be aligned Mean angular changes between T1 and T3 were <1°. There was no significant difference in stability in multi-segment maxillary osteotomies (P= 0.22) or with bone grafting (P= 0.31). In conclusion, anterior fixation alone in the Le Fort I osteotomy results in a stable maxillary position at 1 year postoperative
In 2014, Wu et al. used functional three-dimensional FEA model of bioabsorbable internal fixation and compared the stability of 5 methods of resorbable internal fixation devices application in maxillary Lefort l fracture. They analyzed the stability of fixations under four chewing pattern and they conducted that the fixation using two bioabsorbable plates was not stable and the Zygomaticomaxillary pillars fixation was more stable than the others This presentation will demonstrate the appropriate technique for the fixation of a complex midface fracture with 1.3 and 1.5 adaption plates. The trauma has. The trauma surgeon must be familiar with the numerous individual bones that compose the midface in order to analyze how the multiple single units form a combined structural support system. 1-3 René LeFort, in his paramount work in 1901, described this support system and the classical fracture patterns of the midface in trauma. 4-6 After his cadaver studies, LeFort was able to conclude that midfacial fractures will vary with the architectural structure of the bone, thickness of the bone. In most cases, Lefort fractures need to be treated with open reduction with internal fixation regardless of type. In few cases when the patient is edentulous, the fracture can be treated with observational approach. Furthermore, in edentulous patients, osteosynthesis plates can be difficult due to the atrophic nature of the maxillary bones Fixation of the palatal vault with resorbable plates is a possible technique to improve transverse stability. Larger samples are necessary to provide statistical significance. Discover the world's.
The treatment of LeFort III fracture is complex and involves various factors. Any complication if present should be treated as a priority. Generally, the treatment is aimed at stabilizing the mobile fracture segment with the help of maxillo-mandibular fixation This exercise will demonstrate the appropriate surgical technique for the advancement and fixation of both a LeFort I and a bilateral sagittal split osteotom..

The aim was to evaluate three different biodegradable polylactic acid- (PLA-) based osteosynthesis materials (OM). These OM (BioSorb, LactoSorb, and Delta) were used in 64 patients of whom 55 (85.9%) had fractures of the zygoma, five (7.8%) in the LeFort II level, two of the frontal bone (3.1%), and two of the maxillary sinus wall (3.1%) The sequencing in the management of panfacial fracture still remains a conundrum. The two schools of thought in the management of panfacial fracture are bottom-top, outside-in and top-bottom, inside-out .Variations exist among these sequences but major consensus exists between the above two sequence, as it is the first point of fixation in panfacial fracture 
CranioFacial Fixation Block Modules. The OsteoMed CranioFacial Fixation System is comprised of plates, screws and instrumentation used for fixation of craniofacial, maxillofacial and mandibular fractures. This single tray meets the rigid fixation needs of all craniomaxillofacial surgery applications, from pediatric craniofacial surgery to adult mandibular trauma 4. Conclusion. Although both one-stage 1and 2-stage procedure have been used for the correction in patients with maxillary retrusion by cleft lip and palate, the authors believe that the computer-assisted preoperative simulation for positioning and fixation of plate in 2-stage procedure combining maxillary advancement by distraction technique and mandibular setback surgery proves to be highly. METHODS: A select group of 100 patients who required midfacial skeletal advancement with fixation of either 2.0-mm copolymeric poly L-lactic acid/polyglycolic acid (PLLA/PGA) or standard 2.0mm titanium plates and screw fixation at the LeFort I type advancement were chosen for this study. Criteria for inclusion included patients with either. The purpose of this study was to determine retrospectively the stability of the LeFort I osteotomy after one-piece maxillary impaction and wire fixation. Cephalograms of 31 patients were evaluated before surgery, immediately after surgery, in fixation, and postfixation. All subjects had characteristics of excessive vertical maxillary growth The LeFort I osteotomy is the most commonly used orthognathic surgical method and consists of an intermaxillary ligation, with an external arch that is fixed to the skull with multiple screws, an intraoral splint whose fixation to the external traction hooks is intranasal and with surgical wires
A standard LeFort I osteotomy was performed using the printed jigs. Temporary maxillomandibular fixation was done before mobilizing the maxillomandibular complex in a downward and forward direction. Maxilla was rotated counter-clockwise as planned and fixation was done using 4 plates and screws at the buttresses (Figure 2A to D). Iliac crest.
