Stereotactic radiosurgery (SRS) is an established treatment for vestibular schwannoma (VS), primarily for tumors smaller than 3 cm in diameter. Its role in larger tumors remains controversial and is generally limited to carefully selected patients. This study evaluated long-term outcomes of primary single-session SRS for VS, stratified by tumor size.

Discussion
Signed responses from readers of the wire.
Tumor size within the sub-3 cm range is a meaningful predictor of outcomes and complications after stereotactic radiosurgery for vestibular schwannoma; audiologists co-managing these patients should be aware that size-stratified risk counseling may be warranted, pending review of the full study data.
Refining outcome expectations by tumor size could sharpen shared decision-making between neurosurgeons, radiation oncologists, and audiologists managing vestibular schwannoma patients.
- 01Retrospective study of stereotactic radiosurgery outcomes for sporadic vestibular schwannomas under 3 cm.
- 02Tumor size within this range influenced both treatment efficacy and complication rates.
- 03Sporadic vestibular schwannomas (not linked to NF2 gene mutation) were the focus.
- 04Findings may inform size-stratified patient counseling for radiosurgery candidates.
- 05Study design is retrospective, limiting causal conclusions.
Tumor size affects clinical outcomes and complication rates following stereotactic radiosurgery for sporadic vestibular schwannoma.
