Management of vestibular schwannoma (VS) remains controversial. Very small VSs represent a pivotal group: on one hand, they pose the least risk to the patient from the perspective of being small; yet, not recommending treatment may result in missing a critical window for achieving the best outcome. This debate fundamentally hinges on whether treatment improves upon the natural history of the disease....
Evidence supports defining a size threshold below which vestibular schwannomas can be managed with active surveillance alone, potentially reducing overtreatment of very small tumors.
Establishing a validated size threshold for surveillance could standardize management protocols and reduce unnecessary intervention for very small vestibular schwannomas.
- 01Very small vestibular schwannomas may have a distinct natural history compared to larger tumors.
- 02A size-based threshold could justify a watch-and-wait surveillance strategy.
- 03Findings may reduce overtreatment and associated risks in this patient subgroup.
- 04Data on growth rates and stability inform when intervention becomes necessary.
Very small vestibular schwannomas have a unique natural history that substantiates a size-threshold-based surveillance approach.
