Le Fort I maxillary osteotomy is a widely performed procedure to correct dentofacial disharmonies. The integration of virtual surgical planning (VSP), custom cutting guides and patient-specific implants (PSI) has significantly improved the accuracy of maxillary repositioning by facilitating the transfer of the virtual plan to surgery. Traditionally, most cutting guides and plate designs engage both the piriform and zygomaticomaxillary (ZM) buttress areas, necessitating extensive flap reflection and greater surgical invasiveness. This presentation will discuss the evolution from classic to minimally invasive approaches using custom guides and PSIs while maintaining surgical accuracy and stability. Focus will be placed on the use of modified cutting guides and implants that enable conservative incisions and tissue dissection, thus reducing morbidity and enhancing postoperative recovery.
Learning Objectives:
At the conclusion of this presentation, participants should be able to:
Understand the details and nuances of virtual surgical planning for maxillary osteotomies.
Differentiate between different designs for cutting guides and patient specific plates for maxillary osteotomies.
Obtain the best workflow when using PSI for different patient needs in maxillary osteotomies.
