Orbital Morphometry: A Computed Tomography Analysis

Area of Science:

• Anatomy
• Medical Imaging
• Craniofacial Complex

Background:

• The human orbit is a complex anatomical region crucial for craniofacial evaluation.
• Understanding distances from the orbital rim to vital orbital apex structures is essential for safe surgical procedures.

Purpose of the Study:

• To evaluate and compare orbital apex distances from the orbital rim between genders in the local population.
• To provide data for safe internal orbital dissection limits.

Main Methods:

• Linear measurements were performed on 60 orbits from 30 patients using head CT scans.
• Multiplanar reconstruction modes with 1mm slice thickness were utilized for precise measurements.

Main Results:

• Males exhibited statistically larger orbits than females across most parameters.
• No significant differences were observed between right and left orbits.
• The distance from the posterior ethmoidal foramen to the optic canal was identical between genders.

Conclusions:

• This study establishes safe internal orbital dissection limits for the local population.
• Although male orbits are larger, the difference is clinically negligible, ensuring comparable safety margins.
