Publisher: | Lippincott Williams and Wilkins | Abstract: | The pterion is an important skull landmark because it is located where the frontal, the great wing of sphenoid, parietal, and squamous parts of the temporal bone junction. The objectives of this study were to determine the localization and the shape of pterion on skulls and to find out the distances between the pterion and some certain anatomic landmarks on neighboring structures. The study was performed on the skulls of 128 (256 sides) adult West Anatolian people. All of the morphometric measurements of the distances between the pterion and the anatomic landmarks were performed using a Vernier caliper with an accuracy of 0.1 mm. The pterion was classified into 4 types: the sphenoparietal, frontotemporal, stellate, or epipteric types. The incidences of types of pterion in the skulls were also found as the sphenoparietal type (85.2%), the epipteric type (8.2%), the stellate type (5.5%), and the frontotemporal type (1.1%). The mean (SD) distances from the center of the pterion to the zygomatic arch were measured as 40.02 (4.06) mm and 39.88 (4.01) mm; to the frontozygomatic suture, 31.80 (4.51) mm and 31.44 (4.73) mm; to the zygomatic angle, 41.54 (4.95) mm and 41.35 (5.14) mm; to the mastoid process, 82.48 (5.45) mm and 81.81 (5.50) mm; and to the external acoustic meatus, 53.29 (4.55) mm and 56.22 (4.60) mm, on the right and left sides, respectively. The mean (SD) distances between the foremost point of pterion and the anterior edge of the lateral wall of the orbit were 31.02 (5.78) mm and 32.31 (5.79) mm on the right and left sides, respectively. The localization and the shape of pterion are of importance because it is an anatomic landmark and should be of use in surgical approaches and interventions via the pterion. © 2014 Mutaz B.
