Title: The skull vibration induced nystagmus test (SVINT): Clinical benefit in unilateral vestibular lesions and anterior canal dehiscence diagnosis
Biography
Biography: Georges Dumas
Abstract
Bone conducted vibration (BCV) applied to the mastoid of patients with unilateral vestibular loss (UVL) usually elicits a skull vibration induced nystagmus (SVIN) beating toward the intact side. In patients with unilateral superior semicircular canal dehiscence (uSCD) this procedure causes a SVIN beating toward the affected side. This study sought to establish the stimulus optimum frequency and location (mid-line or Mastoids) for these two groups of patients and to compare uSCD with bilateral SCD (bSCD) patient responses.
