Abstract
Computed tomography scanning is one of the most practical and precise diagnostic imaging methods that can be utilized to evaluate the head in birds. This study aimed to present the normal anatomical data of the head of the Rose-ringed parakeet (Psittacula krameri) using the CT method. In this research, the features of this bird's head were investigated in terms of bones, joints, muscles, sinuses, and other constituent tissues. The current retrospective cross-sectional study used carcasses of six adult Melango parrots (3 males and 3 females) with an average age of 1–5 years and an average weight of 115–125 g. Following preparing the CT images, the head of each parrot underwent gross anatomy studies. Based on the results, reconstructed CT images could identify most structures of the Rose-ringed parakeet head. Parietal, mandible, occiput, maxillary, preimaxillary, palatine, pterygoid, quadrate, and temporal bones, epithelial membranes, external ear canal and bony labyrinth, ossicles and entoglossal bones, different parts of the infraorbital sinus, brain hemispheres, and various parts of the eyeball and conchae of the nasal cavities were examined in CT images. The results related to the CT evaluation and anatomical examination of the Melengo parrot’s head demonstrated a high correlation. The results of this research can be employed for identifying anatomical features, examining different species of the Rose-ringed parakeets (Psittacula krameri), teaching anatomy, and interpreting CT scan images, as well as performing clinical examinations and treating this type of parrot.
