Abstract

This study was carried out to determine the osteometric features of the skull by using three dimensional computedtomography images in gazelles (Gazelle subgutturosa). In the study, nine skull samples of adult gazelles (Gazella subgutturosa) were used. Images of the skull sections of 0.625 mm thickness were acquired by using a computer tomography device with 64 detectors applying 80 kV, 200 mA and 639 mGY. Three-dimensional images of the skull samples were reconstructed and morphometricmeasurements (39 linear, 1 volumetric and 1 surface area) were performed by using the software program MIMICS 12.1. Mean skull volumes in males and females were found to be 115.74±2.43 cm3 and 87.69±1.09 cm3 while the mean skull surface areas in males andfemales were 79.62±8.56 cm2 and 77.34±1.18 cm2, respectively. Significant differences between males and females for median frontal length (MFL), frontal length (FRL), upper neurocranium length (UNCL), greatest length of the lacrimal bone (GLLB), oral palatal length (OPL), length of the upper molar row (LUMR) and the greatest neurocranium breadth (GNCB) were observed. The difference in the cranial index between males and females was statistically significant (P

Özet

Bu çalışma; ceylan kafatasının bilgisayarlı tomografi görüntülerini kullanılarak kafatası kemiklerinin osteometrik özelliklerini belirlemek amacıyla yapılmıştır. Çalışmada 9 adet erişkin ceylan (Gazella subgutturosa) kafatası kullanıldı. Kafataslarının 64 dedektörlü CT cihazı ile 80 kv, 200 MA, 639 mGY ve 0,625 mm kesit kalınlığında görüntüleri alındı. Bu görüntüler MIMICS 12.1 programı yardımıyla üç boyutlu yapıya dönüştürülerek morfometrik ölçümleri (39 linear, 1 hacim ve 1 yüzey alanı) yapıldı. Erkeklerde kafatasının ortalama hacim değeri 115,74±2,43 cm3, dişilerde 87,69±1,09 cm3 olarak tespit edilirken cranium’un ortalama yüzey alanı erkeklerde 79,62±8,56 cm2 , dişilerde 77,34±1,18 cm2 olarak bulundu. Çalışmada, median frontal uzunluk (MFL), frontal uzunluk (FRL), üst neurocranium uzunluğu (UNCL), lacrimal kemiğin maximum uzunluğu (GLLB), oral palatal uzunluk (OPL), üst molar diş sırası uzunluğu (LUMR) ve en büyük neurocranium genişliği (GNCB) parametrelerinde dişi ve erkekler arasındaki farklar istatistiksel olarak anlamlı bulundu. Cranial index değeri açısından dişi ve erkekler arasındaki fark istatistiksel olarak anlamlıydı (P
