Microsurgical resection of foramen magnum meningioma thru a transcondylar approach: 3D operative vid

Microsurgical resection of foramen magnum meningioma thru a transcondylar approach: 3D operative vid

Foramen magnum (FM) meningiomas are challenging lesions. We present the case of a 38-year-old female with neck pain, dysphonia, and slight twelfth nerve palsy. Imaging workup was highly suggestive of an FM meningioma, and microsurgical resection with the aid of intraoperative neurophysiological monitoring was indicated. A transcondylar approach was employed, the vertebral artery was mobilized, and the tumor was completely removed. Postoperative MRI demonstrated complete resection. There were no signs of cervical instability. The patient presented with improvement of her symptoms and no new neurological deficit on follow-up. FM meningiomas can be successfully resected using a transcondylar approach, since it increases the exposure of the ventral FM, allowing the surgeon to work parallel to the skull base and flush with the tumor’s attachment. Informed consent was obtained from the patient for publication of this operative video. Guilherme H. W. Ceccato,1 Rodolfo F. M. da Rocha,2 Duarte N. C. Cândido, MD,3 Wladimir O. Melo, MD,4 Marcio S.
