[[Retrosigmoid approach]] for [[cerebellopontine angle meningioma]] is a safe surgical procedure. 

The modern management of CPA meningiomas should achieve as complete a resection as possible within reasonable limits, considering that a small residual tumor can be controlled fairly easily with [[radiosurgery]] for a relatively long time

====Key points====

Careful examination of preoperative studies is needed to identify anatomical peculiarities.

Patient positioning: the head must be gently flexed and its vertex gently tilted toward the floor.

Neurophysiologic monitoring and intraoperative navigation.

Craniectomy: partial exposure of the transverse and sigmoid sinuses.

Curvilinear dural incision reflected laterally to minimize the risk of sinus injury.

Opening the cerebellomedullary cistern for CSF drainage and cerebellar relaxation.
