Objective: The aim of this study is to analyze dried skulls morphometrically to determine the prevalence of the pterion types and discuss their clinical significance. There are four types of sutural pattern: sphenoparietal, the sphenoid and parietal bones are indirect contact; frontotemporal, the frontal and temporal bones are indirect contact; stellate, all the four bones meet at a point; and epipteric, when there is a small sutural bone uniting all the bones.
Material and Methods: A total number 150 adult dried skulls of unknown age and sex studied for the pterion types. For this study calvaria’s intact human skulls collected from the Akdeniz University Medical Faculty Department of Anatomy. We separated the pterions into 4 groups as sphenoparietal, frontotemporal, stellate and epipteric. We measured distances between the center of the pterion and some important points.  Morphometrical measurements are taken with digital caliper.   
Results: In the present study all types of pterion are observed. Sphenoparietal type of pterion was 63%, frontotemporal type of pterion was 2%, stellate type was 19% and epipteric type of pterion was 16% in our study. According to measurements pterion was lying aproximately 3.98 cm above the arcus zygomaticus and 3.4 cm behind the frontozygomatic suture.  
Conclusion: The pterion has close relation with the branches of middle meningeal artery and Broca’s motor speech area on the left side. Therefore knowledge and understanding of the type and location of the pterion and its relation to surrounding bony landmarks is important, especially for neurologists, neurosurgeons, radiologists and anthropologists.
Key words: Antero-Lateral Fontanelle, Stellate, Epipteric Bones.
