A Novel Minimally Invasive and Cost-Effective Internal Fixation of the Le Fort I Fracture by Using Intermaxillary Fixation Screw and Wire: A Technical Note

Le Fort I fractures represent a significant proportion of craniofacial trauma, often occurring alongside other injuries to the craniomaxillofacial region. Management options include open reduction and internal fixation (ORIF) or skeletal suspension, each with its limitations and considerations. This technical note presents a novel technique for managing isolated Le Fort I fractures using intermaxillary fixation (IMF) screws, offering a minimally invasive alternative to ORIF. The technique involves the strategic placement of IMF screws in the stable zygomatic bone, coupled with arch bar fixation and wire manipulation for maxillary fragment reduction. This approach is cost-effective, can be performed under local anesthesia, and provides stability without the need for prolonged maxillomandibular fixation (MMF). The simplicity and efficacy of this technique make it suitable for emergency settings and cases where traditional approaches may not be feasible. However, this technique is only feasible in isolated Le Fort I fractures and is contraindicated in comminuted Le Fort I fractures and in edentulous patients with upper jaw involvement.
