Summary
Custom 3D-printed orbital implants effectively reconstruct facial fractures, reducing dislocation risks and improving orbital volume and exophthalmos. This patient-specific approach offers a feasible solution for acute orbital wall injuries.
Area of Science:
- Biomaterials Engineering
- Craniofacial Surgery
- Medical Imaging
Background:
- Orbital wall reconstruction is vital for significant fractures.
- Traditional planar implants risk dislocation and require screws.
- Need for improved implant designs to minimize complications.
Purpose of the Study:
- To evaluate customized 3D-printed implants for orbital wall reconstruction.
- To reduce complications and dislocation risk associated with traditional implants.
- To assess the efficacy of patient-specific implants in restoring orbital volume and reducing exophthalmos.
Main Methods:
- Prospective study of 12 Korean patients with orbital wall injuries.
- 3D printing of patient-specific implants using bioactive glass ceramics and poly-e-caprolactone.
- CT scans for pre- and post-operative measurements of orbital volume and exophthalmos.
Main Results:
- 3D implants manufactured in an average of 4.6 days.
- Significant reduction in orbital volume difference (<0.1 mL) and exophthalmos (<1 mm).
- No post-operative complications observed at 2 weeks, 3 months, and 6 months.
Conclusions:
- 3D-printed patient-specific implants are feasible and effective for acute orbital wall reconstruction.
- Customized implants restore bony orbital volumes and reduce exophthalmos.
- The novel implant design with notches enhances stability and reduces dislocation risk.
