Background: The foramen ovale is an oval opening in the greater wing of sphenoid bone transmitting the mandibular nerve as its major content. It serves as an important landmark for neurosurgeons in certain procedures as to gain access to trigeminal nerve. Therefore, its topographic position in relation to adjacent bony landmarks provides useful tool during these procedures. Aim: To analyse the morphometric measurements of the foramen ovale among South Indian population. Material and Methods: Morphometric analysis was carried out on 104 foramina ovalia of 52 dry human skulls from South India. Following dimensions of foramen ovale were measured: antero-posterior length, transverse width, distance (d1) from tubercle of root of zygoma to the centre of the foramen (CF) and distance (d2) from the midline of the base of the skull to CF. Results: The mean antero-posterior length was 7.0±2.17mm on right side and 6.8±1.40mm on left side, mean transverse width was 5.0±0.42mm and 4.70±0.91mm on right and left side respectively. Mean d1 was 32.58±1.72mm on right side and 32.75±1.76mm on left side. Mean d2 was 25.83±1.26mm on right side and 25.08±1.31mm on left side. Conclusion: Regional variations in the morphometric measures may be useful in neurosurgical procedures like administration of anaesthesia involving the mandibular nerve.
