Evaluation of Vestibular Function in Diagnosis of Vestibular Schwannomas

摘要

Vestibular schwannomas(VS)are benign tumors of the vestibular nerve.The common first symptoms are hearing loss and tinnitus,followed by imbalance,vertigo,and facial nerve involvement.The subjective symptoms of VS patients are not consistent with the severity of vestibular lesions and the results of vestibular tests,which often interfere with clinicians’diagnoses.Thus,the main screening and diagnostic methods for VS are audiometry and magnetic resonance imaging(MRI),ignoring the evaluation of vestibular function at the source of pathological lesions.With the development and improvement of vestibular evaluation technology and its wide application in the clinic,modern vestibular examination technology can reflect the severity and frequency of vestibular lesions and compensation from multiple perspectives,providing an objective basis for the diagnosis and treatment of vestibular diseases.In this report,we review the results and characteristics of vestibular tests in VS patients and further clarify the clinical value of vestibular function assessment in the diagnosis and treatment of VS.
