Pain is a common distressing symptom in dental practice. Depending upon the cases, different techniques are used to relieve pain. One of these is peripheral trigeminal nerve block. Peripheral trigeminal nerve block anaesthesia has proved to be an effective and convenient way to anaesthetise large regions of oral and maxillofacial complex. This block can be intraoral or extra oral. The intraoral route is through the greater palatine foramen in which the dental surgeons enter into the pterygopalatine fossa, where the maxillary nerve is situated. The morphological variations in the position of greater palatine foramen may be of clinical importance in the administration of local anaesthesia and in palatal surgery. In the present study, the distance of greater palatine foramen from the median palatine suture, and from the posterior border of hard palate have been noted, and the position of greater palatine foramen relative to the maxillary molars, as well as the direction of the foramen have been examined.

KEY WORDS: Greater palatine foramen; Peripheral trigeminal nerve block; Pterygopalatine fossa; Maxillary molars.
