title: Is otolithic vertigo accompanied by hearing loss caused by sacculocochlear endolymphatic hydrops?
abstract: CONCLUSIONS
  Otolithic vertigo is sometimes accompanied by hearing loss. Otolithic vertigo accompanied by hearing loss seems to be caused by sacculocochlear endolymphatic hydrops.
  
  
  OBJECTIVE
  To clarify the lesion site and pathophysiology of otolithic vertigo (OV) accompanied by hearing loss.
  
  
  METHODS
  The clinical records of four patients (two men and two women) that had been diagnosed with OV accompanied by hearing loss according to pre-determined diagnostic criteria were reviewed.
  
  
  RESULTS
  The patients' main symptoms involved a sensation of movement in the pitch plane. All of the patients had low frequency-dominant hearing loss and either exhibited decreased cervical vestibular evoked myogenic potentials (cVEMP) or did not produce cVEMP. Two patients produced normal ocular VEMP (oVEMP). Caloric tests obtained normal results in all patients.
