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.
翼点是颅骨的一个重要标志，因为它位于额骨、蝶骨大翼、顶骨和颞骨鳞部的交界处。本研究的目的是确定翼点在颅骨上的位置和形态，并找出翼点与相邻结构上某些特定解剖标志之间的距离。该研究在128名（256侧）成年安纳托利亚西部人的颅骨上进行。使用精度为0.1毫米的游标卡尺对翼点与解剖标志之间的所有距离进行形态学测量。翼点分为4种类型：蝶顶型、额颞型、星型或翼上型。颅骨中翼点各类型的发生率分别为蝶顶型（85.2%）、翼上型（8.2%）、星型（5.5%）和额颞型（1.1%）。翼点中心到颧弓的平均（标准差）距离，右侧为40.02（4.06）毫米，左侧为39.88（4.01）毫米；到额颧缝，右侧为31.80（4.51）毫米，左侧为31.44（4.73）毫米；到颧角，右侧为41.54（4.95）毫米，左侧为41.35（5.14）毫米；到乳突，右侧为82.48（5.45）毫米，左侧为8l.81（5.50）毫米；到外耳道，右侧为53.29（4.55）毫米，左侧为56.22（4.60）毫米。翼点最前端到眶外侧壁前缘的平均（标准差）距离，右侧为31.02（5.78）毫米，左侧为32.31（5.79）毫米。翼点的位置和形态很重要，因为它是一个解剖标志，在经翼点的手术入路和干预中应会有所帮助。
