Brain injuries are a significant cause of morbidity and mortality worldwide. Auditory and vestibular dysfunction may occur following trauma to the temporal bone TB , including the lateral skull base. The porcine model is a commonly used large animal model for investigating brain injury. TBs were analyzed for major anatomical structures and compared to human species.
Porcine temporal bone anatomy was readily identifiable by HRCT. Although some variability exists, the ossicular chain, vestibule, cochlea, course of the facial nerve, and skull base are similar to those of humans. Major differences included position of the external auditory canal and mastoid, as well as presence of the petrous carotid canal. Study findings may serve as an atlas to evaluate the porcine middle and inner ear, as well as lateral skull base injuries for future porcine brain injury models or other studies that require CT-based analysis.

Statistical Analysis The Wilcoxon signed rank test was performed to compare the scores of image resolution between UHR-IR and zUHR for the aforementioned individual structures round window, incudomallear joint, oval window, incudostapedial joint, spiral lamina in the basal turn, and scutum and reconstruction planes axial, coronal, and Poschl.
Results Study Sample We identified 8 patients 2 male and 6 female; age ranges, 16—75 years of age who had initial examinations with the zUHR technique and underwent a follow-up scan by using the new UHR-IR technique.
