MORPHOMETRIC STUDY OF THE GREATER PALATINE FORAMEN IN THE DRIED BONES OF EASTERN INDIA
Journal Title: International Journal of Anatomy and Research - Year 2018, Vol 6, Issue 3
Abstract
Introduction: Greater palatine foramen is a very important landmark for administering anesthesia in maxillofacial and dental surgeries. Getting the anesthesia correct each time is a technical manoeuvre, which require sufficient amount of clinical skill and experience. The anatomical landmark has been described by many authors but as per the data in the eastern Indian population it is sparse. This study aims to define the greater palatine foramen according to various landmarks. Materials and Methods: One hundred and three skulls from two medical colleges of eastern India were studied by the first and second authors separately and consecutively. All the skulls were examined for any broken parts in the hard palate and in the greater palatine foramen region. Only the skulls that were intact in these areas were considered for the study. Result: The mean distance of the greater palatine foramen to the incisive foramen was 35.45mm in the males and 34.82mm in the females. The average distance between the greater palatine foramen and the midline maxillary suture was 13.22mm in the males and 12.98 mm in the females. In 85.92% cases we found the GPF to be oval in shape and it opened in to the oral cavity antero-medially in 58% of the cases. With respect to the molar teeth, in 42.71% of the cases the greater palatine foramen was present opposite the anterior ½ of the 3rd molar.
