ABSTRACT:

Background: Hard palate forms an important area in the skull, between the oral cavity and the nasal cavity. It is formed anteriorly by the palatine process of maxillae and posteriorly by the horizontal plates of palatine bones of both sides, forming a cruciform suture in the midline. The hard palate play a crucial role in articulation of speech and any significant variations in its morphology may lead to alterations in the speech of an individual.

Materials and Methods: The present study was conducted on 50 dry skulls of unknown sex and age obtained from the department of Anatomy, K S Hegde Medical Academy, Mangaluru. Various morphometric measurments were taken from the skull using digital vernier calipers.

Results: The length, breadth and height of the hard palate was 50.45mm±2.86mm, 39.38mm±2.28mm and 10.31mm±2.21mm respectively. The distance between the greater palatine foramen and middle maxillary suture was 14.80mm±1.14mm on right and 14.83mm±1.08mm on left side. The position of greater palatine foramen in 82% of the skulls was opposite 3rd molars and 18% was between 2nd and 3rd molars. The palatine index showed that, 66% were Leptostaphyline, 18% were Mesostaphyline and 16% were Brachystaphyline The palatine height index showed that 56% were Chamestaphyline, and 44% were Orthostaphyline.

Conclusion: The present study identifies the commonest location of greater palatine foramen to be opposite the 3rd maxillary molars which is useful for clinicians to perform procedures on palate. The morphometry is useful in comparing the skulls of various origin.

Key words: Hard palate, Maxilla, Molar tooth, Morphometry, Skull.
