What this trial studies

This study investigates the effects of stereotactic radiosurgery (SRS) on patients with vestibular schwannoma, focusing on cochlear, vestibular, gustatory, and facial nerve functions. It includes both retrospective analysis of past patients treated between 2014 and 2021 and prospective follow-up of current patients. Data will be collected on demographics, clinical characteristics, and MRI features, alongside quality of life assessments through questionnaires. The aim is to evaluate the predictive value of tumor characteristics on hearing preservation and vestibular function.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with unilateral vestibular schwannoma treated with either SRS or MRI-based observation.

Not a fit: Patients with previous treatments for vestibular schwannoma or those with profound hearing loss may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could enhance understanding of how radiosurgery affects hearing and balance, potentially leading to improved treatment strategies for vestibular schwannoma.

How similar studies have performed: While there have been studies on radiosurgery for vestibular schwannoma, this specific focus on ototoxicity and quality of life assessments is relatively novel.
