![]() ![]() It is named in accordance with the LeFort I horizontal fracture pattern described by Rene LeFort in 1901. It can also be utilized to facilitate surgical access for the removal of tumors or the reduction of complex midfacial fractures. The LeFort I osteotomy is a horizontal maxillary osteotomy utilized in the correction of midface deformities allowing movement anteriorly/posteriorly, vertically, rotationally, and with segmentation: expansion. We conclude that the routine use of a custom maxillary disimpaction splint can result in improved outcomes and decreased complications of LeFort osteotomy procedures in patients with cleft and traumatized palate. No surgical complications related to the maxillary downfracture have been noted during this period of time. The custom maxillary disimpaction splint has been routinely used in our clinic from September 2019 to the present for LeFort osteotomies in patients with a compromised primary palate. This allows for a stable grip of the disimpaction forceps blades and provides protective coverage of the cleft, traumatized palate, or alveolar bone graft site during the downfracture. The base of the splint is fabricated from a two-layered biocryl material, and the palatal area is built with soft-cushion rebase material. ![]() The splint is designed to cover the palate and occlusal surfaces to increase retention and minimize splint movement during the maxillary downfracture portion of the surgical procedure. To help prevent these complications, we developed a custom disimpaction splint. Such potential complications include trauma or formation of a fistula of the palatal, oral, or nasal mucosa trauma to adjacent teeth and fracture of the palate and alveolar bone. Both the cleft and traumatized palate have poor bony support, which leads to possible complications when the disimpaction forceps are used during the downfracture of the maxilla. Patients requiring these procedures typically have a craniofacial cleft, other congenital craniofacial deformities, or severe facial trauma. Precise recognition of these deviations and recognition of additional associated fractures is pivotal in their management, assisting the surgeon in determining the treatment plan, such as the surgical approach and the order in which to fix the various fractured components.LeFort I, II, and III osteotomies are commonly used in complex craniofacial reconstruction. Mandibular and zygomatic bone fractures were found to be common associations with Le Fort injuries, occurring in 58% and 33% of the cases respectively.Ĭonclusion: Fractures occurring in modern practice often deviate from the traditional Le Fort classification. Nine patients had Le Fort fractures and additional fractures. Results: Of the 52 cases, 12 (23%) had Le Fort injuries, with true Le Fort fractures occurring in only 1, and 11 deviating from the classic description. Deviations from the true Le Fort types, which are often depicted in the literature as occurring bilaterally and symmetrically, were documented these included unilaterality, occurrence of several Le Fort fractures on one side of the face, occurrence of several Le Fort fractures on different levels and on different sides of the face, and occurrence of other fractures in addition to Le Fort fractures. ![]() Injuries were classified using the Le Fort classification system. Method: A retrospective study comprising the review of CT scans of 52 patients with highvelocity facial fractures was performed between April 2007 and March 2013. Objectives: A retrospective study to define facial bone fractures occurring subsequent to highvelocity trauma. In modern practice, in a quaternary-level referral hospital, patients are often admitted following high-velocity injuries that mostly result from motor vehicle collisions. This classification, however, was based on low-velocity trauma. Background: In the early 20th century, René Le Fort studied facial fractures resulting from blunt trauma and devised a classification system still in common use today. ![]()
