Vestibular dose predicts toxicity in stereotactic radiosurgery for vestibular schwannomas.

ABSTRACT:

Introduction

Stereotactic radiosurgery (SRS) provides excellent tumor control in small and medium vestibular schwannomas (VS), but its impact on the vestibular system remains uncertain. This study examines the effects of SRS on subjective vestibular symptoms, vestibular function, and potential predictors of symptom worsening.

Materials and methods

A retrospective analysis was conducted on adult VS patients treated with SRS over eight years. Vestibular symptoms were graded at baseline and six months post-SRS. The vestibular sensory organs (VSO) were defined as the combined volume of the saccule, utricle, and ampullae. Vestibular function was assessed with bithermal, bilateral caloric testing, video head impulse testing, and vestibular evoked myogenic potentials. Two illustrat
