Van Kedilerinde Glandula Lacrimalis’in Bilgisayarlı Tomografi Görüntülerinden Morfometrik İncelenmesi

Bu çalışma, Van kedilerinde glandula lacrimalis’in bilgisayarlı tomografi (BT) görüntüleri üzerinden morfometrik ve volümetrik ölçülerini elde etmek ve bu ölçüm değerlerinin hem homotipik varyasyonlar hem de seksüel dimorfizm bakımından biyometrik farklılıklarını belirlemek amacıyla yapıldı. Çalışmada 8 erkek, 8 dişi olmak üzere toplamda 16 adet erişkin sağlıklı Van kedisi glandula lacrimalis’ine ait BT görüntüsü kullanıldı. Sağ ve sol glandula lacrimalis’e ait transversal, sagital ve dorsal kesitlerden morfometrik ölçümler alındı. Daha sonra, volümetrik elipsoid yöntem kullanılarak her bir glandula lacrimalis’in hacim değerleri elde edildi. Morfometrik ve volümetrik değerlerin istatistiki analizi yapıldı. Yapılan morfometrik incelemelerde sağ ve sol glandula lacrimalis’e ait ortalama uzunluk, genişlik, yükseklik değerlerinin erkek kedilerde sırasıyla ortalama 14.26 ± 1.59 mm, 8.59 ± 0.44 mm, 3.85 ± 0.21 mm; dişilerde ise, bu değerler sırasıyla ortalama 11.01 ± 1.01 mm, 7.59 ± 0.96 mm, 3.01± 0.25 mm olarak belirlendi. Ayrıca, glandula lacrimalis’in maksimum hacim değeri erkeklerde ortalama 257.00 ± 45.29 mm3, dişilerde ortalama 133.60 ± 34.77 mm3 olarak hesaplandı. Sonuç olarak, erişkin sağlıklı Van kedilerinde glandula lacrimalis’e ait ölçüm parametrelerinin istatistiksel olarak cinsiyetler arasındaki farklılıkları bilgisayarlı tomografi görüntüleri kullanılarak tespit edildi.

Morphometric Examination of the Lacrimal Gland from Computed Tomography Images in Van Cats

This study was carried out to obtain morphometric and volumetric measurements of the glandula lacrimalis from computed tomography (CT) images in Van cats and to determine the biometric differences of these measurement values in terms of both homotypic variations and sexual dimorphism. In the study, CT images of a total of 16 adults healthy Van cats glandula lacrimalis, 8 males and 8 females, were used. Morphometric measurements were taken from the transverse, sagittal and dorsal sections of the right and left glandula lacrimalis. Then, volume values of each glandula lacrimalis were obtained by using the volumetric ellipsoid method. Statistical analysis of morphometric and volumetric values was performed. In the morphometric examinations, the mean length, width, and height values of the right and left glandula lacrimalis were determined as average 14.26 ± 1.59 mm, 8.59 ± 0.44 mm, 3.85 ± 0.21 mm, in male cats; average 11.01 ± 1.01 mm, 7.59 ± 0.96 mm, 3.01 ± 0.25 mm, in female cats, respectively. Also, the maximum volume value of glandula lacrimalis was calculated as average 257.00 ± 45.29 mm3 in males and average 133.60 ± 34.77 mm3 in females. As a result, the differences between the genders of the measurement parameters of the glandula lacrimalis were detected using computed tomography images in healthy adult Van cats.
