The aim of this study was to evaluate the long-term efficacy and safety of Gamma Knife surgery (GKS) for sporadic vestibular schwannoma (VS), focusing on the durability of tumor control and the necessity of extended posttreatment imaging surveillance.

Clinicians co-managing vestibular schwannoma patients treated with Gamma Knife radiosurgery may reasonably discuss reduced MRI surveillance frequency with neurosurgery after 10 years of documented tumor stability, pending institutional protocol updates.

Evidence supporting reduced long-term surveillance after Gamma Knife radiosurgery could lower patient burden and healthcare costs while maintaining safety for a large population of vestibular schwannoma survivors.
