Aim: The infra orbital foramen is an anatomical structure with an important location, through which the infra orbital vessels and nerve exits. The present study was conducted to determine the mean distance between the infra orbital foramen and infra orbital margin, mean distance between piriform aperture and infra orbital foramen, mean distance between the anterior nasal spine and infra orbital foramen on both side and as well as shape of foramen.
Materials and Methods: 43 skulls were studied The following parameters were taken.(A)-The distance between the most superior point of the infraorbital foramen (IOF) up to the infraorbital margin (IOM) ,(B),  The distances between the center of the infraorbital foramen (IOF) and the piriform aperture (PA) were also measured.
Results: The mean distance between IOF-IOM was 6.85 mm ±1.72 (6.75 mm -Right Side (RS) and 6.95 mm -Left side (LS)) and between IOF-PA was 18.43 mm ±2.38(18.50 mm (RS) and 18.30 mm (LS). Statistical analysis of the data showed significant differences between the right side and the left side distances of IOF and IOM, verified by the Student’s-t Test. (C)-The mean distance between infra orbital foramen and the anterior nasal spine(ANS) was 33.68+3.63mm, on right was 33.35+3.25mm and left was 34.23+3.75mm (Table 1). (D)-The transverse diameter of infra orbital foramen was 2.68+0.72mm and(E)-vertical diameter is 2.58+0.74mm.
Conclusion: Knowledge of infra orbital foramen is very helpful for neurovascular surgeons.
