Surgical Management of Foramen Magnum Meningiomas
Ahmed Mohamed Badr;
Abstract
Surgical treatment of foramen magnum meningiomas has greatly improved after the description of the anterolateral and posterolateral approaches.
These lateral approaches provide the most direct route to laterally or anterolaterally located lesions without or with minimal retraction. The posterolateral approach provides better access and exposure than the midline posterior suboccipital approach and is less time consuming than the anterolateral transcondylar approach.
The bone drilling is usually limited to the lateral mass of the atlas with or without the posterior 1/3 of the occipital condyle depending on the relation of the tumor to the vertebral artery, respectively.
In conclusion, found that the vast majority of foramen magnum meningiomas can be resected from the posterior corridors with no added morbidity. The post. FMMs should be resected by post. suboccipital approach, and antrolateral FMMs should be resected by far lat approach as the patient begins to become symptomatic when the tumor enlarges and the brain stem is displaced and the corridor widens (Fig. 7-1). Transcondylar approach is considered necessary to create an appropriate corridor in anterior FMMs.
Intraoperative neurophysiologic monitoring, as well as the adjuvant use of image guided surgery, can add much to the safety of procedures allowing safe removal with better radicality.
