The anterior part of the base of cranium has the hard palate formed by the palatine process of the maxillary bone anteriorly and the horizontal plate of palatine bone posteriorly. At the posterior part of palatine bone medial to the maxillary alveolar arch two foramina are present. They are the larger greater palatine foramen and a smaller lesser palatine foramen. 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 greater palatine foramen is essential for the clinicians while performing the maxillary nerve block, failure of which leads to the damage of the greater palatine nerve. Sixty 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. The mean value of the diameter of the right side greater palatine foramen was 3.93 ± 0.12 mm. The mean value of the diameter of the left side greater palatine foramen was 4.16 ± 0.19 mm. The present study may be helpful for the clinicians to locate greater palatine foramen for giving local anaesthesia in molar tooth extraction, palatal surgeries and also helps to avoid post extraction haemorrhage of greater palatine vessels.
