The aim of this study was to investigate the incidence of the pterygospinous and pterygoalar bony bridges and the variations in these bony bridges among Anatolians. A total of 452 adult dry skulls (258 males and 194 females) of the Anatolian population were investigated for both the pterygospinous and the pterygoalar bony bridges. In 80 of the 452 dry skulls (37 male and 43 female), it was possible to inspect the cranial cavity. In these skulls, sellar and sphenopetrous bridges were also investigated. In addition to this, the mandibular nerve of 9 fixed cadavers was carefully dissected and the distribution of its branches was determined on both sides. Complete pterygospinous osseous bridges were found in 5.5% of the samples and complete pterygoalar bridges in 4.9%. In the dry skulls with removed calvaria, complete sellar osseous bridges were found on both sides in 34.2% of specimens, complete pterygospinous bridges in 8.8% and complete pterygoalar bridges in 7.5%. No complete sphenopetrous bridges were found. In the cadaveric study, nerve entrapment due to a pterygoalar ligament on the left side was found in one cadaver. Such variations should be kept in mind in clinical complaints such as mandibular neuralgia, especially during chewing.
本研究的目的是调查翼棘和翼突骨桥的发生率以及这些骨桥在安纳托利亚人群中的变异情况。对总共452具安纳托利亚人群的成年干燥颅骨（258例男性和194例女性）进行了翼棘和翼突骨桥的研究。在452具干燥颅骨中的80例（37例男性和43例女性）中，可以检查颅腔。在这些颅骨中，还对鞍桥和蝶岩桥进行了研究。此外，仔细解剖了9具固定尸体的下颌神经，并确定了其双侧分支的分布。在5.5%的样本中发现了完整的翼棘骨桥，在4.9%的样本中发现了完整的翼突桥。在去除颅骨的干燥颅骨中，34.2%的标本双侧发现了完整的鞍骨桥，8.8%发现了完整的翼棘桥，7.5%发现了完整的翼突桥。未发现完整的蝶岩桥。在尸体研究中，在一具尸体中发现左侧翼突韧带导致神经受压。在诸如下颌神经痛等临床症状中，尤其是在咀嚼时，应牢记这种变异情况。
