Vestibular schwannoma (VS) stereotactic radiosurgery (SRS) requires high target conformality and rapid dose falloff to spare adjacent organs at risk (OARs), particularly the brainstem. HyperArc (HA) is an automated noncoplanar volumetric-modulated arc therapy (VMAT) approach designed to standardize and streamline cranial SRS planning and delivery....
No actionable change for most audiologists — dosimetric comparison findings are relevant to radiation oncology and neurosurgery planning teams managing vestibular schwannoma; audiologists involved in pre/post-radiosurgery hearing monitoring should note that both technologies aim to spare cochlear and neural structures, but this study does not report hearing outcome data.
Vestibular schwannoma is a key diagnosis managed across audiology, neurotology, and oncology; optimizing radiosurgery planning to spare hearing-critical structures directly affects the audiological outcomes of treated patients.
