ABSTRACT
OBJECTIVE:
To characterize the natural history of hearing loss for patients presenting with serviceable hearing (SH) who undergo a wait-and-scan approach for sporadic vestibular schwannoma (VS) using aggregate time-to-event survival analysis. STUDYDESIGN:
Systematic review.SETTING:
Published international English literature, January 1, 2000 to May 31, 2020. PATIENTS Patients with sporadic VS entering a wait-and-scan approach with SH at diagnosis.INTERVENTIONS:
Observation with serial MRI and audiometry.RESULTS:
In total, 3,652 patients from 26 studies were included for analysis. Mean age at diagnosis was 58.8 years (SD, 4.1). Mean follow-up was 49.2 months (SD, 26.5). In total, 755 patients (21%) failed conservative treatment and underwent radiosurgery or microsurgery at the time of last follow-up. The average loss to follow-up was 6.9% (SD, 11.1). A total of 1,674 patients had SH at the time of diagnosis. Survival rates for maintaining SH were 96% at 1 year, 77% at 3 years, 62% at 5 years, and 42% at 10 years following diagnosis.CONCLUSION:
In this systematic review, aggregate data from 3,652 patients across 26 studies show consistent patterns in progression of hearing loss during observation for patients with sporadic VS as a function of time. As an easy-toremember conservative benchmark for those presenting with SH at diagnosis approximately 75% retain SH at 3 years, 60% at 5 years, and 40% at 10 years.
