THE PURPOSE of this exhibit is to demonstrate the various cell groups of the temporal bone:
Certain specimens show unusual extension of some cell groups. Dense septa separating various groups are demonstrated.
A correlation is shown between the different roentgenographic positions and the information to be derived from each, with drawings and specimens. A correlation between mastoid pneumatization and age is demonstrated by means of x-ray studies.
Over-all view of exhibit.
Specimen demonstrating relationship of the tympanomastoid suture to the facial nerve. A wire demonstrates the course of the nerve.
Specimen showing course of a large mastoid emissary vein vulnerable at mastoidectomy.
Specimen showing relationship of the outer part of the tympanomastoid suture to the facial nerve. The nerve course is depicted by a string.
Specimen showing a tympanomastoid tract (indicated by wire bristle) extending
