Orbital volume (OV) in African American females is smaller than in Caucasian females, potentially impacting orbital reconstruction. No significant differences were found between genders or laterality in males.
Area of Science:
- Craniofacial surgery
- Medical imaging
- Anthropometry
Background:
- Accurate orbital volume (OV) restoration is crucial for successful orbital reconstruction.
- Understanding racial differences in OV is important for surgical planning.
Purpose of the Study:
- To investigate potential differences in orbital volume (OV) between African American (AA) and Caucasian subjects.
- To inform surgical approaches in orbital reconstruction.
Main Methods:
- Retrospective observational study of 60 subjects (120 orbits) with maxillofacial CT scans.
- Orbital volume calculated using OsiriX MD software by two independent examiners.
- Statistical analysis using independent samples t-test to compare OV between racial groups and genders.
Main Results:
- No significant difference in mean OV between AA (22.38 cm³ ) and Caucasian (23.23 cm³) subjects (P=.07).
- No significant difference in mean OV between AA males (23.92 cm³) and Caucasian males (24.17 cm³) (P=.71).
- Significantly smaller mean OV in AA females (20.84 cm³) compared to Caucasian females (22.28 cm³) (P=.013).
Conclusions:
- African American females exhibit a smaller orbital volume compared to Caucasian females, which may affect orbital reconstruction outcomes.
- Laterality (left vs. right orbit) did not show significant differences in OV for either racial group.
- These findings highlight the need for race-specific considerations in orbital volume restoration during reconstructive surgery.

Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
