Morphometric Analysis of the Infraorbital Canal, Groove, and Foramen in the Indian Population: A Retrospective Analytical Study.

AIM

The aim of this research is to analyse and assess the anatomical variability of the infraorbital canal, groove, and foramen using high-resolution CT images of the Indian population using mimics software.

MATERIALS AND METHODS

A total of 100 high-resolution CT (HRCT) data (200 hemi-faces) with a range of 18-65 years in Digital Imaging and Communication in Medicine (DICOM) format was incorporated in mimics software. Infraorbital foramen (IOF), infraorbital groove (IOG), and infraorbital canal (IOC) were evaluated retrospectively using seven parameters. Statistical analysis was made, and comparisons were made with respect to gender, side, and age groups.

RESULTS

Out of 100 HRCT data obtained, 74 were of men and 13 were of women, with an average age of 32.5 years. Of 200 hemifaces, the average length of the IOC was 14.99 ± 6.25 mm, the average length of the IOG was 15.25 ± 7.87 mm, the average total length was 30.26 ± 3.36 mm, and the average transverse diameter of IOF was 2.02 ± 0.48 mm. The mean distance from IOF to the infraorbital margin (IOM) was 7.35 ± 1.67 mm, IOC to the medial wall was 16.02 ± 2.22 mm, and IOC to the lateral wall was 16.99 ± 2.47 mm.

CONCLUSION

Measurement data of infraorbital apparatus varies among different populations. This study contributes valuable knowledge regarding the measurements of the IOC, IOG, and IOF, particularly within the Indian population. This information can help by minimizing the risk of complications and improve the treatment planning for operative and anesthetic procedures.
