In this study, anatomical, morphometric and volumetric analyses of the mandible of Hamdani sheep were performed using computed tomography (CT) and three-dimensional (3D) software. For this purpose, 16 (eight males, eight females) Hamdani sheep heads were used. Images of these heads were taken on a 64-detector CT device applying 80 kV, 200 MA, 639 mGY, and 0.625 mm section thickness. Scan images of the mandible of each subject were converted into three-dimensional models using 3D software and reconstructed. Surface, volume and linear measurements (24) of the mandible were performed on the models. All the measurements were expressed as mean ± SD. The examinations determined that the mandible's volume and surface area values were more significant in males than females. Mandible length (GOC-ID) was 169.01±0.74 mm, and its height (GOV-CR) was 95.50±0.64 mm in males. In morphometric evaluations, statistically significant differences were observed between males and females in L2 (PC-ID), L6 (GOC-FMN), L14 (MTR-MH), L19(SI), Volume and Surface area measurement parameters (P<0.05). It is thought that the morphometric data obtained will be a reference in pathological conditions, taxonomy studies, and interventional surgical treatment applications to be performed on the site.

Hamdani koyununun mandibulasının üç boyutlu rekonstrüksiyonu ve morfometrik analizi: Bilgisayarlı tomografi (BT) çalışması

Öz

Bu çalışmada Hamdani koyunlarının mandibula’sının anatomik, morfometrik ve volümetrik özellikleri bilgisayarlı tomografi (BT) ve üç boyutlu (3D) yazılım programı kullanılarak tespit edildi. Bu amaçla 16 adet (8 erkek, 8 dişi) Hamdani koyunu kafası kullanıldı. Kafaların 64 dedektörlü BT cihazında 80 kv, 200 MA, 639 mGY ve 0.625 mm kesit kalınlığında görüntüleri alındı. Her bir deneğin mandibula’ya ait tarama görüntüleri özel bir 3D yazılım programı yardımıyla üç boyutlu modellere dönüştürülerek rekonstrükte edildi. Modeller üzerinde mandibula’nın yüzey, hacim ve doğrusal ölçüm (22 adet) analizleri yapıldı. İncelenen tüm özellikler ortalama ± SD olarak ifade edildi. Yapılan incelemelerde, erkeklerde mandibulanın hacim ve yüzey alanı değerlerinin dişilerden daha büyük olduğu tespit edildi. Erkeklerde mandibula uzunluğu (GOC-ID) 169.01±0.74 mm ve yüksekliği (GOV-CR) ise 95.50±0.64 mm olarak belirlendi. Morfometrik değerlendirmelerde dişi ve erkekler arasında L2(PC-ID), L6(GOC-FMN), L14(MTR-MH), L19(SI), hacim ve yüzey alanı ölçüm parametrelerinde istatistiksel olarak anlamlı farklar gözlendi (P<0.05). Elde edilen morfometrik verilerin, patolojik durumlar, taksonomi çalışmaları ve bölge üzerinde yapılacak girişimsel cerrahi tedavi uygulamalarında referans olacağı düşünülmektedir.
