Ocular and Cervical Vestibular Evoked Myogenic Potentials to 500 Hz Fz Bone-Conducted Vibration in Superior Semicircular Canal Dehiscence

Abstract

In response to 500 Hz Fz BCV an asymmetrical oVEMP n10 with a significantly increased amplitude of contralesional oVEMP n10 (compared with population values of healthy subjects) is a simple useful indicator of SSCD, confirmed by the Cz response. oVEMP testing with 500 Hz Fz BCV allows very simple, very fast identification of a probable unilateral SSCD.
