Summary
Preoperative digital evaluation of orbital fractures aids surgeons in precise implant selection and placement. This technique ensures accurate anatomic restoration without increasing surgical time.
Area of Science:
- Ophthalmology
- Plastic Surgery
- Medical Imaging
Background:
- Internal orbital fractures present complex reconstructive challenges.
- Accurate restoration of orbital anatomy is crucial for function and aesthetics.
Purpose of the Study:
- To assess the utility of preoperative digital anatomic implant evaluation for internal orbital fractures.
- To determine the impact of digital planning on surgical outcomes and efficiency.
Main Methods:
- Retrospective review of orbital fracture repair cases utilizing digital implant modeling.
- Comparison of surgical times between digitally planned cases and matched controls.
Main Results:
- 25 patients (26 orbits) underwent virtual preoperative fitting.
- No intraoperative or postoperative complications or need for revision surgery were reported.
- High accuracy achieved, with an average maximum deviation of 1.9 mm from the preoperative plan.
Conclusions:
- Preoperative digital fracture assessment and virtual cutting guide creation are valuable tools for orbital surgeons.
- This approach facilitates anatomic restoration of the orbit.
- Digital planning does not significantly increase operative time.
