Delayed Endolymphatic Hydrops: Episodic Vertigo of Delayed Onset after Profound Inner Ear Hearing Loss

  • Tamio Kamei
  • Kenji Watanabe


No matter what the cause, a prolonged case of profound inner ear hearing loss can induce otologic symptoms, similar to those of Meniere’s disease, called delayed endolymphatic hydrops (DEH). There are two types of DEH [9]: the ipsilateral, in which vestibular symptoms arise from the profoundly deaf ear, and the contralateral type, in which cochlear and/or vestibular symptom occurs in the better-hearing ear mostly with normal hearing.
