Tree-dimensional reconstruction of multidetector computed tomography images of paranasal sinuses of New Zealand rabbits

Abstract

This study was conducted to produce a 3-dimensional reconstruction using multidetector computed tomography (MDCT)images of the anatomic structures forming the paranasal sinuses of New Zealand rabbits and to present biometric properties of thesinuses and conchae. A total of 16 adult New Zealand rabbits, comprising 8 males and 8 females, were included in the study. Afer high-resolution MDCT images of the paranasal sinuses were obtained, they were reconstructed using a 3-dimensional modeling program(Mimics) by overlapping the images and the biometric measurements of the structures forming the paranasal sinuses. Te maxillarysinuses of New Zealand rabbits were made up of 2 compartments. It was also observed that their conchae were more developed withan uneven structure. Te frontal sinus and sphenoid sinus were not seen and the ethmoid sinus was not observed. Tere was not asignifcant statistical diference between sinus and conchae constituting the right and lef paranasal sinuses of the same sex; however,a signifcant statistical diference was observed between the sexes (P < 0.05). Tis study s data can be used for purposes of modernanatomy education and research and may form a basis as a model for future studies to be performed on the paranasal sinuses.
