Meckel Cave Atrophy

A small space located in the skull where several crucial nerves pass through, including the trigeminal nerve responsible for facial sensation.

The shrinking or wasting away of tissue, in this case, referring to the gradual deterioration? of the nerves within the Meckel cave.

Types:
