Describe the natural history of small intrameatal vestibular schwannomas.
No immediate practice change is warranted; this retrospective series adds natural-history data for small intracanalicular vestibular schwannomas but does not establish new management thresholds — existing watch-and-wait protocols remain appropriate pending prospective evidence.
Reliable natural-history data for intracanalicular vestibular schwannomas is essential for counseling patients about observation versus intervention and for calibrating growth-based treatment triggers.
- 01Retrospective case series from a tertiary referral center tracking growth of small intracanalicular vestibular schwannomas.
- 02Describes natural history including rates of growth, stability, and spontaneous regression.
- 03Published ahead of print in Otology & Neurotology (2026).
- 04Tertiary-center data may not reflect community practice or less selected patient populations.
- 05Findings are relevant to shared decision-making discussions around watch-and-wait management.
Small intracanalicular vestibular schwannomas display heterogeneous growth patterns, including periods of stability and spontaneous regression.
