THE PURPOSE of this exhibit is to demonstrate the various cell groups of the temporal bone:

  • Squamous Occipital

  • Zygomatic Mastoid

  • Precarotid Infralabyrinthine

  • Postcarotid Apical

  • Supracarotid Precochlear


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.
