Approaches to the 4th ventricle

Subspecialty: Neuro-oncology

Type: Clinical Summary

This review synthesizes the pathoanatomic principles and stepwise microsurgical techniques for lesions associated with the 4th ventricle — including lateral the telovelar trajectory, the tonsillouvular fissure approach and strategies for lesions extending into the Cerebellopontine Angle (CPA) — and relate these technical advances to outcomes (extent of resection, progression-free survival, overall survival) and perioperative management in children. Overview The review provides methodical anatomic descriptions of the common approaches ( telovelar , lateral CPA dissection and tonsillouvular fiss…
