Radicality and revision surgery in vestibular schwannoma treatment: balancing optimal outcomes with unavoidable necessity

Revision microsurgery for vestibular schwannoma (VS) after failure of prior microsurgery and/or stereotactic irradiation represents a technically demanding scenario with uncertain functional outcomes. We aimed to evaluate operative strategy, extent of resection, tumor control, and functional results-primarily facial nerve outcomes-in patients undergoing revision VS surgery in a high-volume tertiary center.

Surgeons managing vestibular schwannoma recurrence after prior microsurgery or radiation should consult this review for guidance on radicality decisions, but routine audiology practice is not directly changed; referral pathways for patients with treatment failure should remain in place.

As more vestibular schwannoma patients receive initial stereotactic radiation, the volume of complex revision surgical cases is rising, making evidence-based guidance on surgical radicality increasingly important for multidisciplinary teams.
