Background: Greater Palatine Foramen (GPF) is located medial to the upper third molar tooth and may vary with the sutural growth occurring between palatine and maxillary bones. The precise knowledge about the morphometry of GPF is essential for the clinicians while performing the maxillary nerve block, failure of which leads to the damage of greater palatine nerve.

Aim: To determine the morphometry of GPF and its variations if any.

Materials and Methods: One hundred (100) adult dry human skull bones irrespective of sex and age were studied. The position, shape, direction and distance of greater palatine foramen with its variations were noted on both sides.

Results: In 68.5% skulls GPF was located opposite to the third molar, in 22.5% skulls between second and third molar, in 8% skulls distal to the third molar and in 1% skulls opposite to second molar tooth. In 89.5% skulls the shape of the foramen was found to be oval whereas in 10.5% skulls it was round. In 69% skulls the foramen was directed anteromedial, in 23% skulls anterolateral and in 8% skulls it was directed anteriorly.

Conclusion: The present study helps the clinicians to locate GPF for giving local anaesthesia in molar tooth extraction, palatal surgeries and also helps to avoid post extraction haemorrhage of greater palatine vessels.

Keywords: Skull bone, greater palatine foramen, position, direction.
