Erkek ve bayanlarda kafatası kemiğinden geometrik morfometri metoduyla cinsiyet tayini ve ramus flexure

Bu çalışmanın amacı; erkek ve bayanlarda kafatası kemiğinden geometrik morfometri metodu yardımıyla cinsiyetin belirlenmesidir. Araştırmaya, Kaman Lisesinde okuyan ve voleybol takımında yer alan, yaşları 15-17 arasında değişen 12 erkek ve 13 kız öğrenci gönüllü olarak katılmıştır. Bu çalışmaya katılan öğrencilerin sol lateral craniofacial ve mandibular röntgenleri alınmıştır. Daha sonra elde edilen verilere geometrik morfometri analizi uygulanmıştır. Röntgenler üzerinde anatomik 14 adet homolog referans noktası tespit edilmiştir. Örneklerin Relation Warp (RW) analizinden elde edilen sonuçlar da; RW1 %30, RW2 %21 olmak üzere, her iki bileşen toplam varyansın %51’ini, geri kalan bileşenler ise farklılıkların %49’unu açıklamıştır. RW analiz grafiğinde, genelde bayan örneklerin ana ekseninin solunda, erkeklerin ise sağında toplandığı gözlendi. Cinsiyetler arasındaki deformasyon grid’lerin farklılıkları ve vektörel yönlenmeler arasındaki değişiklikler açıkça gözlendi. Nitekim cinsiyet farklılığı açısından en önemli farklılığın ramus mandibulae düzeyinde olduğu belirlendi. Erkeklerdeki bu durum ramus flexure yapısını açıkça ortaya koymaktaydı (%85 oranında). Bayanlarda ise %15 oranında ramus flexure yapısı gözlendi. Sinus frontale bu çalışmada makroanatomik yönden incelendiğinde, cinsiyetler ve bireyler arasında, hatta aynı bireylerde bile farklılıkların bulunduğu tespit edildi.

Determine the gender from cranial bone by using geometric morphometric method in males and females and ramus flexure

The purpose of this study was to determine the gender from cranial bone by using geometric morphometric method in males and females. The sample of this study constituted of 12 volunteer male and 13 female volleyball players aged between 15 to 17 from a high school at Kaman. Left lateral craniofacial and mandibular x-rays were taken from the students. Geometric morphometric analyzes were applied to the all data. 14 homolog referans noktası anatomic points were determined from x-rays. Relation Warp (RW) analyzes indicated that while RW1 was 30%, the RW2 was 21 % and these two components explains the 51 % of total variance. The other two components explains the 49% of the differences. RW analyzes graphic indicated that, generally women’s were placed at the left side of the main axis and men’s were placed at the right side. The deformation grid differences between the genders and changes between vectors were clearly become visible. The result indicated that there was a significant difference between the genders in “ramus mandibulae”. This case clearly exposes the “ramus flexure” structure 85% ratio in male and 15% in females. In this study, there were sinus frontale differences between genders and also in same individuals in the macro anatomical point of view.
