What Is Epitympanum?

The epitympanum, often known as the attic or epitympanic recess, is essentially the most superior portion of the tympanic cavity.

It is that portion of the tympanic cavity superior to the axial airplane between the tip of the scutum and the tympanic phase of the facial nerve 1,3.

Posteriorly the epitympanum is in direct continuity with the mastoid antrum by way of the aditus advert antrum, and thence the mastoid air cells.

Its foremost contents are the pinnacle of the malleus and physique and brief technique of the incus, which articulate with one another on the incudomalleolar joint.

The regular look of those buildings on axial ct provides rise to the ice cream cone signal.
