Background:
The sella turcica is an important skull formation due to its close anatomical relationship with the pituitary gland. Therefore, the shape and morphometry of the sella turcica provide crucial preliminary information for the determination of cases.
Objectives:
The aim of this study was to determine the morphometry of the sella turcica in cats and its relationship with gender and skull morphometry using computed tomography (CT).
Methods:
In this study, CT images of 18 female and 15 male adult cats were used for morphometric measurements. Six different morphometric measurements of the sella turcica were performed on CT images. Similarly, seven different morphometric measurements were made on the skull and six different indices of the skull were calculated. Additionally, 3D modelling of the hypophyseal fossa, dorsum sellae and tuberculum sellae that form the sella turcica was performed.
Results:
Statistically significant gender-based differences were observed in sella diameter, sella height cranialis and sella width (p < 0.01). In the morphometric measurements obtained from the skull, differences were observed in skull length, cranial length, external height of cranium, internal length of the cranium and external length of the cranium (p < 0.01). Similarly, a difference was found in cranial width (p < 0.05). All measurements obtained from the skull were determined to be higher in male cats. Differences were observed in the cranial index, internal cranium index and external cranium index, and these indices were found to be higher in females. A strong positive correlation was observed between sella diameter and sella width. Similarly, a very strong positive correlation was found between skull length and cranial length.
Conclusion:
In this study, the morphology and morphometry of the sella turcica in cats were revealed. In sella turcica and skull morphometry, a strong positive correlation was found between sella diameter/sella width and skull length/cranial length. The findings obtained from the sella turcica and skull, which is clinically important in humans, are thought to contribute to future clinical studies in cats. Additionally, the study's findings are expected to contribute to characterizing the morphometry of the domestic cat's skull.

The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...
01:22Sutures of the Skull
Sutures are immobile joints between adjacent bones of the skull. The narrow gap between the bones is filled with dense, fibrous connective tissue that unites the bones. The long sutures located between the skull bones are not straight but instead follow irregular, tightly twisting paths. These twisting lines tightly...
01:27Cranial Bones: Lateral View
The temporal bone forms the lower lateral side of the skull. The temporal bone is subdivided into several regions. The flattened upper portion is the squamous portion of the temporal bone. Below this area and projecting anteriorly is the zygomatic process of the temporal bone, which forms the posterior portion of the zygomatic arch. Posteriorly is the mastoid portion of the temporal bone. Projecting...
01:14Cranial Bones: Superior and Posterior View
The frontal bone is the single bone that forms the forehead. At its anterior midline, between the eyebrows, there is a slight depression called the glabella. The frontal bone also forms the supraorbital margin of the orbit. Near the middle of this margin is the supraorbital foramen, the opening that provides passage for a sensory nerve to the forehead. The frontal bone is thickened just above each supraorbital margin,...
