title: Profound high-frequency sensorineural hearing loss treatment with a totally implantable hearing system.
abstract: OBJECTIVE
  This study seeks to assess the efficacy of the Envoy Esteem totally implantable hearing device in treating profound high-frequency sensorineural hearing loss.
  
  
  METHODS
  Five patients with profound high-frequency hearing loss participating in a prospective, multi-center, nonrandomized Food and Drug Administration clinical trial.
  
  
  METHODS
  Implantation with Esteem totally implantable hearing device and comparison to baseline unaided and aided conditions.
  
  
  METHODS
  Speech reception threshold and word recognition scores (WRS) at 50 dB HL presentation level.
  
  
  RESULTS
  Preoperative speech reception threshold improved from an unaided 65 dB and aided 48 dB average to 26 dB with the Esteem at 12 months. WRS at 50 dB scores improved from an unaided 10% and aided 23% average to 78% postoperatively.
  
  
  CONCLUSIONS
  The Esteem totally implantable middle ear hearing device provides appreciable functional gain and improvement in WRS to rehabilitate hearing in patients with a profound high-frequency sensorineural hearing loss.
