Orbital Floor Reconstruction: Restoring Volume with Patient-Specific Implants

The bony orbit suspends the globe in a precisely calibrated volume. Reconstruction errors of even half a millimetre change globe position enough to produce diplopia or enophthalmos. It is the specialty where patient-specific implants deliver the most visible functional difference.

How the implant is designed

From a thin-slice CT, the fractured orbit is virtually reduced and the mirrored contralateral orbit defines the target. The implant spans stable anterior, medial, lateral and posterior landmarks, restoring the floor contour and the posteromedial bulge — the region where most reconstruction errors occur. Flanged edges lock onto intact bone, often eliminating screws.

Verification in theatre and after

• Design target: mirrored, uninjured contralateral orbit
• Critical zone: posteromedial bulge at the inferior orbital fissure
• Material: typically 0.3–0.6 mm titanium mesh
• Post-op CT overlay quantifies the achieved reduction

Outcomes

Comparative series report markedly lower rates of residual enophthalmos and diplopia with patient-specific implants versus preformed plates in complex two-wall fractures.
