Stereotactic Radiosurgery in Primary Treatment of Sporadic Small to Medium (<3 cm) Vestibular Schwannomas: A Systematic Review and Meta-Analysis.

Objective: To analyze the literature regarding the use of stereotactic radiosurgery as the primary treatment of vestibular schwannoma to further evaluate efficacy and treatment-related neurologic deficits.

Methods: Online databases were queried to identify relevant studies from January 2001 to December 2020. Full-text articles in English for sporadic vestibular schwannoma treated primarily with radiosurgery and documented hearing preservation data were reviewed.
