In a single-arm, single-center IRB approved, prospective study, 20 recurrent, previously Irradiated, high-grade meningiomas treated with brain GammaTile™ (cesium-131brachythrapy) had significant improvement in time-to-local disease progression (LC) compared to the same patient (own case control) most recent...

... endonasal approach provides a direct route to ventral foramen magnum (FM) lesions like meningiomas, which are difficult to access. Endonasal access at the FM is limited laterally by the occipital condyles and inferiorly by the C1 anterior arch and the odontoid process, which may need partial resection...
