Morphometric analysis of Infra orbital foramen position in south Indian skulls.

Abstract

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 formen and infra orbital margin, mean distance between piriform aperature 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. Total 125 skulls were used for this study, the results were the mean distance between the infra orbital foramen and the infra orbital margin was 7.13+1.78mm, on right side it was 7.06+1.81mm and 7.20+1.71mm on left. The mean distance between the infra orbital foramen and the piriform aperature was 18.13+1.85mm, on right side it was 18.01+2.03mm and 18.25+2.01mm on left. The mean distance between infra orbital foramen and the anterior nasal spine on right was 33.97+5.80mm and left was 34.73+4.70mm. The knowledge of infra orbital foramen is very helpful for neurovascular surgeons.
