Using 3D Printing and Mirror Image Modeling in Orbital Floor Reconstruction

Area of Science:

• Craniofacial Surgery
• Biomedical Engineering
• Medical Imaging

Background:

• Complex orbital fractures pose significant reconstructive challenges.
• Three-dimensional (3D) modeling and printing offer advanced tools for surgical planning and execution.
• Patient-specific implants can improve outcomes in craniofacial reconstruction.

Observation:

• A pediatric patient with a unilateral complex orbital fracture was treated using intraoperative, in-house 3D-printed models.
• Two models were utilized: a life-size print of the preoperative CT scan and a mirrored reconstruction of the uninjured orbit.
• These models served as sterilized templates for molding a custom resorbable implant.

Findings:

• The 3D-printed models facilitated the precise molding of a custom resorbable implant.
• The patient experienced no postoperative complications.
• At 18-month follow-up, the patient showed no diplopia, headaches, or visual problems, indicating successful orbit reconstruction.

Implications:

• Mirrored-image computer modeling combined with patient-specific 3D printing provides a viable and effective approach for complex orbital fracture repair.
• This technique can lead to improved functional and aesthetic outcomes in pediatric craniofacial surgery.
• In-house 3D printing offers a cost-effective and accessible solution for creating patient-specific surgical aids.
