Hearing loss with delayed onset of vertigo.

The association between the delayed onset of episodic true vertigo and previous sensorineural hearing loss has been previously described. We have reviewed our series of sixty consecutive labyrinthectomies to determine the prevalence of this disorder in this population, and found a variety of etiologic agents of sensorineural hearing loss with subsequent delayed vertigo. Relief from vertigo following surgery has confirmed that the previously deafened ear has been the cause of the vertigo. Case histories are presented and the literature is reviewed.
