VCT reformations of specimen 1. A shows a reformation in the plane of the anterior and posterior crus of stapes and its footplate. B was acquired in a plane through the cochlea and IAC that clearly shows the modiolus; it also shows the bifurcation of cranial nerve VIII due to the air in the dissected specimen. The facial nerve and its canal are shown in the more horizontal section shown in C and more sagittal section shown in D. Part of the proximal vestibular aqueduct (26), a structure that can be traced throughout its length on these scans, is seen in C. Star indicates high jugular bulb; cross, tensor tympani muscle. See Table for numbered annotations.
