Cerebellopontine angle (CPA)

Structure at the margin of the cerebellum and pons.


1- Facial Nerve. (CN VII)

2- Vestibulocochlear nerve (CN VIII)

3- Flocculus of the cerebellum

4- lateral recess of the fourth ventricle

It is where vestibular schwannomas are usually found.

There are great variation in anatomical location and involvement of neurovascular structures in the CPA. With this knowledge, they present certain technical lessons that may be useful in preserving nerve function during surgery and, in doing so, hope to provide neurosurgeons and neurootologists with valuable information that may help to achieve optimum outcomes in patients 1)

Cerebellopontine angle syndrome

Cerebellopontine angle tumor

Surgical access is a considerable surgical challenge.
