title: Single-sided Deafness Cochlear Implantation: Candidacy, Evaluation, and Outcomes in Children and Adults.
abstract: OBJECTIVE
  Although there are various available treatment options for unilateral severe-to-profound hearing loss, these options do not provide the benefits of binaural hearing since sound is directed from the poorer ear to the better ear. The purpose of this investigation was to review our center's experience with cochlear implantation in such patients in providing improved auditory benefits and useful binaural hearing.
  
  
  METHODS
  Retrospective chart review.
  
  
  METHODS
  Twelve adult patients and four pediatric patients with unilateral severe-to-profound hearing loss received an implant in the poorer ear. Outcome measures performed preoperatively on each ear and binaurally included consonant-nucleus-consonant (CNC) monosyllabic words and sentences in noise. The mean pure-tune average in the better ear was within normal range.
  
  
  RESULTS
  Test scores revealed a significant improvement in CNC and sentence in noise test scores from the preoperative to most recent postoperative evaluation in the isolated implant ear. All adult subjects use the device full-time.
  
  
  CONCLUSIONS
  The data reveal significant improvement in speech perception performance in quiet and in noise in patients with single-sided deafness after implantation. Performance might depend on factors including length of hearing loss, age at implantation, and device usage.
