- •The middle ear ossicles have varying normal morphology.
- •The pneumatized incus and malleus are rare normal anatomic variants and should not be confused with pathological erosions.
- •Important to mention a pneumatized ossicle in the radiology report due to potential surgical implications.

It is well known that the middle ear ossicles have varying normal morphology on gross anatomy, but can also be malformed in certain congenital syndromes or eroded in the setting of chronic ear infection or cholesteatoma.
