Özet:

 Purpose: Morphometric measurements of cranial bones in skeletal remains are important for sex determination. Nowadays, radiological imaging techniques such as computed tomography are very useful in obtaining population-specific data. The aim of this study was to evaluate the usefulness of morphometric measurements of the occipital condyles in 3D cranial CT modeling for sex estimation in a Turkish population. Materials and methods: In this study, three-dimensional images of the occipital condyles were obtained by retrospectively using the carotid CT angiography images from the radiology department between 2019 and 2021. In these images, the length, width and height of both occipital condyles, distances between the basion with and the anterior and posterior ends of the occipital condyles, distances between the opisthion the anterior and posterior ends of the occipital condyles, anterior, posterior, minimum and maximum intercondylar distances, maximum bicondylar distance, right and left sagittal condylar angles, sagittal intercondylar angle, were measured. Results: A statistically significant sexual dimorphism was found for all parameters except the left condylar angle measured in the occipital condyles. According to multivariate discriminant analysis models, sex could be estimated with an accuracy of 81.2 to 84.6 for males and 52.9 to 68.8 for females. Conclusion: It was determined that three-dimensional computed tomography images of the occipital condyles can be used in sex estimation.

 Amaç: İskelet kalıntılarındaki kranial kemiklerin morfometrik ölçümleri cinsiyetin belirlenmesinde önemlidir. Günümüzde, bilgisayarlı tomografi gibi radyolojik görüntüleme teknikleri popülasyona özgü veriler elde etmede oldukça faydalıdır. Bu çalışmanın amacı, Türk popülasyonunda cinsiyet tahmini için 3B kranial BT modellemesinde oksipital kondillerin morfometrik ölçümlerinin yararlılığını değerlendirmektir. Gereç ve yöntem: Bu amaçla, radyoloji anabilim dalı tarafından 2019-2021 yılları arasında çekilmiş karotis anjio BT görüntüleri retrospektif olarak kullanılarak oksipital kondillerin üç boyutlu görüntüleri elde edilmiştir. Bu görüntülerde her iki oksipital kondilin uzunluğu, genişliği ve yüksekliği, bazion ile oksipital kondilin ön ve arka uçları arasındaki mesafeler, opistion ile oksipital kondilin ön ve arka uçları arasındaki mesafeler, ön, arka, minimum ve maksimum interkondiler mesafeler, maksimum bikondiler mesafe, sağ ve sol sagital kondiler açılar, sagital interkondiler açı ölçülmüştür. Bulgular: Sol kondiler açı dışındaki tüm parametrelerde cinsiyete göre istatistiksel olarak anlamlı farklılık olduğu ve oksipital kondillerde cinsel dimorfizm bulunduğu saptanmıştır. Diskriminant analizi ile oluşturulan çok değişkenli modellere göre erkeklerde 81,2 ile 84,6, kadınlarda ise 52,9 ile 68,8 doğrulukta cinsiyet tahmini yapılabileceği gösterilmiştir. Sonuç: Oksipital kondillerin üç boyutlu bilgisayarlı tomografi görüntülerinin cinsiyet tahmininde kullanılabileceği saptanmıştır.
