Computed Tomography Imaging of Cavum nasi and Sinus paranasales in the Tuj Sheep

The aim of this study was to scan cavum nasi and sinus paranasales in male Tuj sheep with computed tomography. Skulls of 8 adult male Tuj sheep were used for the study. On the skulls that computed tomography images were received, cavum nasi and relevant anatomic structures were discerned through 2-dimensional images. Surface area and volume of sinus paranasales were determined through 3- dimensional images. Sinus maxillaris was found to extend from the level of mesial cusp of 2nd maxillary premolar tooth to the lateral angle of the eye. Sinus frontalis was found to extend from the interproximal level between the 3rd maxillary premolar and the 1st maxillary molar to the horn base. Total volume and surface area of sinus paranasales in the skulls of Tuj male sheep on the average were found to be 76963,89 mm3, 39595,96 mm2 respectively. The sinuses with the largest and smallest volume were sinus frontalis and sinus lacrimalis, respectively. In conclusion, it is considered that the information and the data obtained in this study will enable researchers to make radiological assessments on cavum nasi and paranasal sinus in Tuj sheep and compare them with other sheep breeds.
