What is a LeFort? Exploring Custom Upper Jaw Surgery

In the realm of maxillofacial surgery, LeFort osteotomy has emerged as a crucial procedure for the correction of craniofacial deformities and malocclusion. Developed by French surgeon René LeFort in the early 20th century, this surgical technique involves separating the upper jaw from the skull to reposition it correctly. Over the years, advancements in technology have revolutionized the execution of LeFort osteotomy, with custom 3D printed guides and plates emerging as the optimal approach. This blog post aims to delve into the intricacies of LeFort osteotomy and explain why the utilization of custom 3D printed guides and plates represents the pinnacle of precision and efficiency in this procedure.


The LeFort osteotomy technique allows for the repositioning of the maxilla, providing significant improvements in facial aesthetics, occlusion, and overall function. Traditionally, the execution of LeFort osteotomy relied heavily on the surgeon's skill and experience, as well as on intraoperative visual and tactile feedback. However, this approach was not without limitations, as it could result in variability and potential errors due to the subjective nature of the procedure. To address these challenges, modern technologies such as computer-aided design (CAD) and 3D printing have been integrated into the field of maxillofacial surgery.


Custom 3D printed guides and plates have revolutionized the field of maxillofacial surgery, offering unprecedented levels of precision, efficiency, and patient-specific outcomes. These guides and plates are manufactured based on preoperative planning using patient-specific anatomical data obtained from medical imaging techniques such as computed tomography (CT) or magnetic resonance imaging (MRI).


The preoperative planning process involves the creation of a virtual surgical plan using specialized software, allowing the surgeon to visualize the desired osteotomy lines and determine the optimal position for the maxilla. Subsequently, this virtual plan is translated into physical guides and plates through 3D printing technology.


One of the major advantages of custom 3D printed guides is their ability to accurately transfer the virtual surgical plan to the patient's anatomy intraoperatively. These guides act as precise surgical templates, guiding the surgeon's instruments during bone cutting and positioning, thereby ensuring accurate execution of the planned osteotomy. By eliminating the reliance on subjective visual and tactile feedback, custom guides significantly reduce the potential for errors and enhance surgical outcomes.


Similarly, 3D printed patient-specific plates offer numerous benefits in LeFort osteotomy procedures. These plates are meticulously designed to fit the patient's anatomy, ensuring optimal stability and fixation of the repositioned maxilla. The precise fit provided by these custom plates reduces the risk of postoperative complications such as bone displacement, non-union, and implant failure.


Furthermore, the use of 3D printed guides and plates streamlines the surgical workflow, reducing intraoperative time and minimizing the need for complex adjustments during the procedure. The improved efficiency enables surgeons to perform LeFort osteotomy with greater confidence and accuracy, ultimately leading to improved patient satisfaction and reduced postoperative morbidity.



LeFort osteotomy represents a significant milestone in maxillofacial surgery, offering transformative outcomes for patients with craniofacial deformities. The integration of custom 3D printed guides and plates has revolutionized the execution of this procedure. By leveraging advanced technologies such as computer-aided design and 3D printing, surgeons can now plan and execute LeFort osteotomy with remarkable accuracy, minimizing errors and enhancing overall surgical outcomes. The continued advancement and integration by Alfi Oral Surgery of these cutting-edge techniques into clinical practice will undoubtedly shape the future of maxillofacial surgery, further improving patient care and satisfaction in the years to come.
