Özet:

 Purpose: Identification of decomposed human bodies and bone remains is very important in medicolegal examinations. The cranium has an important place in sex estimation due to its dimorphic features. Recent studies in this field have used radiological methods. The present study aimed to examine sexual dimorphism through morphometric analysis of the intracranial volume and Foramen Magnum on Three-Dimensional 3D Volume Rendering Computed Tomography CT images. Material and methods: For this purpose, 3D images were generated after the reconstruction of CT Angiography scans of 87 female and 107 male cases. The length, width, circumference, area, and intracranial volume of the foramen magnum were measured on these 3D images. Results: All measurements except foramen magnum index were greater in males than in females length of foramen magnum p0.0001; breadth of foramen magnum p0.0001; foramen magnum area p0.0001; foramen magnum circumference p0.0001. The single best sex-discriminatory measurement was intracranial volume, with an accuracy rate of 84.5. The best sex-discriminatory parameter in foramen magnum measurements was the length of the foramen magnum, with a rate of 74.2. Intracranial volume was positively correlated with all parameters in male except for the foramen magnum index length p0.000; breadth p0.000; area p0.000; circumference p0.000; index p0.747. Conclusion: Three-dimensional volume rendering CT images showed sexual dimorphism in the intracranial volume and foramen magnum. The use of radiological methods in forensic investigations may allow for examinations of decomposed human bodies without the need for maceration procedures. It may also help create databases by examining population-specific differences in todays societies.

 Amaç: Medikolegal incelemelerde çürümüş cesetlerde ve kemik kalıntılarında kimliklendirme çok önemlidir. Kranium dimorfik özelliklere sahip olduğu için cinsiyet tahmininde önemli yer tutar. Son zamanlarda bu alandaki araştırmalarda radyolojik yöntemlerin kullanıldığı görülmektedir. Bu çalışmada Volume Rendered Bilgisayarlı Tomografi 3B görüntülerinde intrakranial hacim ve Foramen Magnum morfometrik analizinden seksüel dimorfizmin araştırılması amaçlanmıştır. Gereç ve yöntem: Bu amaçla 87 kadın ve 107 erkek olguya ait BT Anjiografi görüntülerinden rekonstrüksiyon sonrası üç boyutlu 3B görüntüler elde edilmiştir. Elde edilen görüntülerde foramen magnum uzunluğu, genişliği, çevresi, alanı ve intrakranial hacim ölçülmüştür. Bulgular: Foramen magnum indeksi dışındaki tüm ölçümlerin erkeklerde kadınlardan daha büyük olduğu görülmüştür foramen magnum uzunluğu p0,0001; foramen magnum genişliği p0,0001; foramen magnum alanı p0,0001; foramen magnum çevresi p0,0001. Cinsiyeti tek başına en iyi ayırt eden ölçüm 84,5 doğruluk oranı ile intrakranial hacimdi. Foramen magnum ölçümlerinde cinsiyeti en iyi ayırt eden parametre ise 74,2 oranı ile foramen magnum uzunluğuydu. Erkeklerde intrakranial hacim foramen magnum indeksi hariç tüm parametrelerle pozitif korelasyon gösterdi foramen magnum uzunluğu p0,000; foramen magnum genişliği p0,000; foramen magnum alanı p0,000; foramen magnum çevresi p0,000; foramen magnum indeksi p0,747. Sonuç: Volume rendered BT 3B görüntülerinde intrakranial hacim ve foramen magnumda cinsel dimorfizm olduğu görülmüştür. Radyolojik yöntemlerin adli incelemelerde kullanılması çürümüş cesetlerde maserasyon işlemlerine gerek kalmadan incelemelerin yapılmasına olanak sağlayabilir. Ayrıca günümüz toplumlarındaki popülasyona özgü farklılıkların araştırılarak veri tabanlarının oluşturulmasına yardımcı olabilir.
