Summary
This study introduces a novel model surgery technique for precise orbital rim repositioning during LeFort III and Monobloc osteotomies. The method enhances planning accuracy for complex craniofacial reconstructions.
Area of Science:
- Craniofacial Surgery
- Orthognathic Surgery
- Surgical Planning
Background:
- Current model surgery and occlusal splint fabrication methods are inadequate for planning orbital rim positioning in LeFort III and Monobloc osteotomies.
- Accurate three-dimensional repositioning of the orbital rims is critical for successful craniofacial reconstruction.
Observation:
- A novel model surgery technique utilizing dual orbital pointers was developed.
- These pointers mark the infraorbital rim during facebow transfer and are subsequently transferred to surgical models.
Findings:
- The described technique allows for precise marking, measurement, and planning of orbital rim repositioning.
- It effectively differentiates orbital rim repositioning from occlusal correction in complex osteotomies, including combined LeFort III/LeFort I procedures.
Implications:
- This technique offers improved accuracy and predictability in planning complex craniofacial surgeries.
- It provides a valuable tool for surgeons performing orbital rim repositioning and orthognathic procedures.
