Background:

Current orbital floor defect reconstruction relies on mirroring, which is time-consuming and neglects natural skull asymmetry.
Statistical Shape Models (SSMs) offer potential for automated and more accurate reconstruction.

Purpose of the Study:

To demonstrate the virtual reconstruction capabilities of an SSM for artificial orbital floor defects.
To evaluate the clinical implementation potential of SSM-based reconstruction.

Main Methods:

An SSM was developed from 131 unaffected midface CT scans.
Artificial defects were created in 19 separate CT scans.
Reconstruction was performed using SSM (Group I) and mirroring (Group II), with comparisons to manual segmentation (control).

Main Results:

SSM reconstruction showed significantly lower errors (0.26-0.34 mm) compared to mirroring (0.7-0.73 mm).
The SSM method achieved higher precision in reconstructing both small and large defects.

Conclusions:

SSM-based reconstruction is an effective and accurate method for orbital floor defects.
This approach enables patient-specific implants, potentially replacing manual bending techniques.
Acknowledging skull asymmetry enhances reconstruction accuracy for injured orbits.
