title: [Efficacy of cochlear implantation for bilateral severe Ménière's disease].
abstract: OBJECTIVE
  To investigate the effecacy of cochlear implantation (CI) improving hearing of Lermoyez's syndrome, we retrospectively analyzed a case of Lermoyez's syndrome whose left ear was extremely severe sensorineural deafness and right ear was severe sensorineural deafness.
  
  
  METHODS
  The patient had completed preoperative audiological examination , vestibular function and imaging examination, then was carried out bilateral endolymphatic sac decompression and left side CI. Follow up after the surgery.
  
  
  RESULTS
  The vertigo could be controlled very well after the bilateral endolymphatic sac decompression surgery, but the hearing loss couldn't be control, so CI was carried out to improve hearing and speech recognition rate. The contralateral hearing also improved significantly after the operation.
  
  
  CONCLUSIONS
  Endolymphatic sac decompression can effectively control. Ménière's disease in patients with vertigo attacks. CI can improve patients' hearing, and speech recognition rate and, also could improve the quality of life. CI was the first choice for the patient of 4 stage Ménière's disease.
