Fixation of lefort 3

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.
