Zap-X Radiosurgery for Skull Base Meningiomas: A Long-Term Follow-Up Case Report.

This article reports two cases of meningioma patients treated with the novel radiosurgical device ZAP-X stereotactic radiosurgery. During the long-term follow-up period of up to four years after treatment, neither patient developed new neurological deficits, and no adverse reactions of Common Terminology Criteria for Adverse Events grade 2 or above occurred. By retrospectively analyzing the clinical diagnosis, treatment processes, and follow-up results of these two patients, this study aims to provide practical references for the large-scale clinical application of this technology.
