ABSTRACT

Background: The infraorbital foramen is located on the maxillary bone about 1 cm inferior to the infraorbital margin. The infraorbital nerve and vessels are transmitted through this foramen. The infraorbital nerve, the continuation of the maxillary or second division of the trigeminal nerve, is solely a sensory nerve. It traverses the inferior orbital fissure into the inferior orbital canal and emerges onto the face at the infraorbital foramen. It divides into several branches that innervate the skin and the mucous membrane of the midface, such as the lower eyelid, cheek, lateral aspect of the nose, upper lip, and the labial gum.

Materials and Methods: Total 300 skulls were used for this study, the following mesearements were recorded, mean distance between the infra orbital foramen and the infra orbital margin on right and left side and average of it.  The mean distance between the infra orbital foramen and the piriform aperature on right and left side measured and average of it also recorded.  The mean distance between infra orbital foramen and the anterior nasal spine on right and left side measured. The transverse and vertical diameter also measured.

Results: Total 300 skulls were used for this study, the results were the mean distance between the infra orbital foramen and the infra orbital margin was 8.48+1.92mm, on right side it was 8.72+2.16mm and 8.20+1.92mm on left. The mean distance between the infra orbital foramen and the piriform aperture was 19.35+3.26mm, on right side it was 19.10+3.42mm and 19.56+3.26mm on left. The mean distance between infra orbital foramen and the anterior nasal spine on right was 34.86+6.73mm and left was 36.12+3.72mm and total average was 35.51+3.75mm. The transverse diameter was 3.16+0.96mm and vertical diameter was 3.03+0.72mm.

Conclusion: The knowledge of infraorbital foramen may be helpful in blocking of nerve passing through it for surgical purpose.

Key words: Infraorbital foramen, Infraorbital nerve, Infraorbital vessels, Face.
