In the current era, Gamma Knife radiosurgery is being used increasingly due to the proximity of vital neurovascular structures. Extensive skull base approaches are confined to the lesions which are not amenable to radiosurgery. However, the skull base approaches are still the standard of treatment for larger meningiomas. In this illustrative case, Tyagi et al. demonstrated an excellent approach combining the sub-temporal and pre-sigmoid posterior petrosectomy for the resection of a large petroclival meningioma.

Placement of the lumbar drain helps in relaxation of the brain during retraction during the bone work. Safe maximal resection with the protection of the brain stem perforators and leaving the residual lesion if adherent to the vital structures is the key to prevent the morbidity of these approaches. In this illustration, we intend to the anatomy of the presigmoid posterior petrosectomy exposure.
