Combined transpetrosal approach for giant petroclival meningioma: 2-dimensional operative video. Neurosurgical focus: Video Vigo, V., Asmaro, K., Nunez, M. A., Moyheldin, A., Jackler, R. K., Fernandez-Miranda, J. C. 2022; 6 (2): V8


Petroclival meningiomas are extremally challenging lesions due to their deep location and close relation to critical neurovascular structures. Several approaches have been described to achieve gross-total resection with low morbidity and mortality. In this 2-dimensional operative video, the authors show a simultaneous combined transpetrosal approach. The patient is a 44-year-old woman with an 8-month history of gait imbalance with evidence of a giant petroclival meningioma on neuroimaging. She underwent a combined middle fossa approach with anterior petrosectomy and retrosigmoid/retrolabyrinthine approach to achieve gross-total tumor resection. The postoperative course was characterized by trigeminal neuralgia, and neuroimaging showed gross-total resection of the tumor. The video can be found here:
