The structure of the mastoid portion of the temporal bone has been thoroughly studied, and the nature and extent of its pneumatization are now well understood. The form, arrangement and relationships of the cells in the petrous portion have not been described with equal thoroughness. The present study finds its justification in the current demand for reliable information concerning the anatomy of this important subdivision of the temporal bone.Siebenmann1 made the first painstaking study of the air cells of the temporal bone; by means of corrosion preparations he demonstrated the shape and connections of the mastoid cells and of certain lesser pneumatic spaces situated beyond the mastoid region, stating that they penetrate everywhere with the exception of the squama and the anterior wall of the external auditory meatus. Illustrations of the corrosion specimens (see also Bezold and Siebenmann2) are still being copied in textbooks of anatomy and otology.

Cholesterol granulomas of the petrous apex are drained through two major extralabyrinthine routes: one, along the posterosuperior chain of air cells, and two, along the anteroinferior chain. Procedures that use the posterosuperior chain approach the apex from the sinodural angle, the base of the zygomatic arch, the attic, or through the arch of the superior semicircular canal. Operations that use the anteroinferior chain reach the apex along the internal carotid canal (Ramadier's operation) or by a posterior infralabyrinthine approach between the descending facial nerve and jugular bulb. Inferior petrous apex cholesterol granulomas may be unreachable by any of these routes, and hence the subcochlear route is proposed as an alternative. The subcochlear approach starts in a triangle bounded superiorly by the cochlea, anteriorly by the internal carotid canal and posteriorly by the deep jugular vein. This operation requires lowering the inferior bony canal wall to the level of the "crutch." It provides access to an inferiorly situated cholesterol granuloma, yet preserves hearing. It allows enough room for the placement of a tube drain from the petrous apex to the mastoid. It is particularly useful when a high jugular bulb precludes the use of the posterior infralabyrinthine route.

“…31 This surgical conclusion is based upon the surgical anatomic fact that the lateral aspect of the tip or, as I prefer to call it, the epiphysis, is very close to the anterior aspect of the inner wall of the tympanic cavity, making it the shortest route of approach to the tip (Figs. 10-13, 16).…”
