Summary
Virtual surgical planning for orbital floor fractures using mirroring or virtual fracture reduction showed comparable accuracy in patient-specific implant placement. Both techniques effectively improved orbital volume and resolved symptoms like diplopia and enophthalmos.
Area of Science:
- Maxillofacial surgery
- Biomedical engineering
- Orthognathic surgery
Background:
- Orbital floor fractures can lead to enophthalmos, diplopia, and facial asymmetry, necessitating surgical reconstruction.
- Virtual surgical planning offers customized reconstruction for orbital floor defects, but the comparative accuracy of different planning techniques is not well-established.
Purpose of the Study:
- To compare the accuracy of patient-specific implant (PSI) placement using two virtual reconstruction techniques: mirroring and virtual fracture reduction.
Main Methods:
- Retrospective cohort study of adult patients with isolated orbital floor fractures treated between 2021 and 2024.
- Virtual surgical planning techniques included mirroring and virtual fracture reduction.
- Primary outcome: PSI accuracy measured by root mean square deviation (RMSD) between planned and postoperative implant positions.
Main Results:
- No statistically significant difference in PSI accuracy was found between mirroring (RMSD: 0.67 ± 0.22 mm) and virtual reduction (RMSD: 0.62 ± 0.24 mm) (P = .6).
- Both techniques significantly improved orbital volume symmetry (P < .05 within groups).
- Preoperative diplopia and enophthalmos improved in both groups postoperatively.
Conclusions:
- Mirroring and virtual fracture reduction demonstrate comparable accuracy for patient-specific implant placement in orbital floor reconstruction.
- The choice of virtual planning technique can be based on surgeon preference and case-specific factors.
- These findings support the flexibility and efficacy of virtual planning in managing orbital floor fractures.
