Study of alignment of infraorbital foramen in human skulls of north indian population

Int J Biol Med Res. 2020; 11(3): 7060-7062  |  PDF File


Aims –Infraorbital Foramen (IOF) is a constant feature on the anterior surface of body of maxilla below the orbital margin. Infraorbital nerve & vessels pass through it. IOF assumes great importance in the field of maxillo- facial surgery & dentistry as Infraorbital Nerve that passes through it is anaesthetised during these procedures. Maxillary tooth is readily visible and palpable landmark. It can be highly helpful in locating IOF. Hence a study was conducted to determine alignment of IOF with maxillary tooth. Methods - The study was conducted in Deptt. of Anatomy, GSVM Medical College, Kanpur. 300 macerated dry adult human skulls of North Indian population belonging to both sexes were selected. The skull was placed in Frankfurt plane. Alignment of IOF with maxillary tooth was noted by suspending a needle with flexible wire from the center of IOF and determining the position of its tip. Result -The present study found that IOF was in same line with 2nd pre- molar in 90.67% of skulls. Conclusion-Thus knowledge of alignment of IOF with maxillary tooth helps in locating its position.
