Background: Foramen ovale and trigeminal nerve is an important anatomical landmark for the therapeutic and diagnostic procedures. One should have a precise knowledge about it. The aim of this study is to know the exact location and position of trigeminal nerve and foramen ovale at their exit. Material and methods: This study was done in the department of Anatomy, AIIMS, Udaipur on 60 dry skulls obtained from the department and also from some students. Damaged skulls are excluded from this study. Distance from lateral surface of zygomatic arch to the lateral rim of foramen ovale of right (M1R) and left (M1L) are recorded in mm. Distance from antero inferior border of zygomatic bone to the anterior end of foramen ovale of right (M2R) and left (M2L) and bilateral antero posterior and transverse diameter of foramen ovale of right and left side (APR, APL, Tr. R, Tr. L) are recorded in mm with the help of compass and digital vernier calliper. Result: The average distance of M1L and M1R is 41.641 and 41.925mm and M2L and M2R is 51.536 and 51.708mm respectively. Average diameter of APL and APR is 6.47 7.02mm respectively. The average Tr. R is 3.595mm and Tr. L is 3.76mm. Conclusion: The average distance of M1 is 51.622mm M2 is 41.783mm. The average AP diameter is 6.745mm and Tr. diameter is 3.6775mm. With the help of these anthropometric measurements the surgeons can mark the exact location of foramen ovale from surface, prior to operative procedure.
