Improving the Treatment Outcome of Naso-Orbito-Ethmoido-Maxillary Fractures Using Virtual Three-Dimensional...

Area of Science:

• Anthropometry
• Craniofacial Surgery
• Medical Imaging

Background:

• Naso-orbito-ethmoido-maxillary (NOEM) fractures result from significant midface trauma.
• These complex fractures are challenging to treat and often misdiagnosed.
• Craniometric analysis offers a method to establish midfacial proportions for treatment.

Purpose of the Study:

• To determine midfacial proportions and anthropometric distances in the Caucasian population.
• To identify potential gender-based differences in these measurements.
• To provide data for improved surgical reconstruction of NOEM fractures.

Main Methods:

• 3D models were generated from CT scans of adult Caucasian patients.
• Measurements were taken between key anthropometric points: nasion (N), dacryon (D), infraorbital foramen (IOF), frontomalare orbitale (FMO), rhinion (Rhi), and porion (Po).
• Statistical analysis, including t-tests, was used to compare measurements between genders.

Main Results:

• Significant gender differences were observed in orbital dimensions (N-FMO, N-IOF, Rhi-FMO, Rhi-IOF) and nasal projection (Rhi-Po, N-Po).
• Nose bridge width (N-D, Rhi-D) and interorbital distance (D-D) also showed significant gender disparities.
• No significant gender differences were found for the N-Rhi measurement.

Conclusions:

• Established midfacial anthropometric data can guide skeletal reconstruction after NOEM fractures.
• These measurements are particularly valuable for treating bilateral comminuted NOEM fractures lacking comparison points.
• The findings highlight the importance of considering gender-specific anthropometry in reconstructive surgery.
