title: Endoscopic Endonasal Approach to Ventral Posterior Fossa Meningiomas: From Case Selection to Surgical Management.
abstract: Clival, petroclival, and foramen magnum meningiomas are challenging lesions to manage independently of the selected surgical approach. The expanded endoscopic endonasal approach (EEA) provided a safe alternative on the armamentarium of skull base approaches. There is a paucity of literature regarding endoscopic management of meningiomas because of certain limiting factors, including rarity of the pathologic condition, technical challenges, expertise of the surgical team, and available resources. The surgical technique, possible complications, and postoperative care are described in detail. This article highlights the important aspects in choosing this surgical approach and managing ventral posterior fossa meningiomas through the EEA.
