1. Original Scientific Paper Morphometric Study of Pterion in Dry Human Skull Bone in North Indian Population by G.S.Gindha, N.S. Mir and R. Agarwal Abstract Pterion is the bony land mark which lies in the norma lateralis of the skull. It is almost H-shaped which is formed by the articulation of four bones with each other i.e. frontal, parietal, greater wing of sphenoid and temporal bones. The pterion is having a great clinical significance. The present study is done on 65 dry human skull mean 130 pteria of both sides of the skull (right and left sides) are studied. The morphological shapes of the pteria are noted, recorded and photographed. The study of the location of pterion from zygomatic-frontal suture and mid-point of superior border of zygomatic arch is done for the land marking of the pterion superficially in the temporal region. The aim of this study is to compare our study with the standard literature and studies done by other authors for any variations in the study. Out of 130 pteria studied, spheno-parietal type of pterion is found in 94 (72.31%) cases, epipteric type in 30 (23.0%) cases, fronto-teporal type in 6 (4.61%) cases and stellate type of pterion is not found in the present study. Mean distance between zygomatico-frontal suture and central point of pterion is found to be (38.71±3.1037) mm on right side and (36.29±3.7307) mm on left side, the mean distance between midpoint of zygomatic arch and center point of pterion is found to be (39±2.5635) mm on right side and (37.00±3.3481) mm on left side. The anatomical variations are important. The epipteric type of pterion sometimes is considered as fractured skull which sometimes create problem neurosurgeons during their surgery. The present study will be helpful for neurosurgeons, anthropologists, forensic medicine and forensic dentologist in their diagnosis and treatment. Download Complete Article
