title: Evaluation of the nonorganic hearing loss suspect.
abstract: OBJECTIVE
  To examine the utility of distortion-product otoacoustic emissions (DPOAEs) in the assessment of the nonorganic suspect because DPOAE analysis constitutes an objective test of hair-cell function that yields audiometriclike data.
  
  
  METHODS
  Retrospective study of clinical findings.
  
  
  METHODS
  Audiology outpatient clinic of our university's medical center.
  
  
  METHODS
  The study cohort comprised 30 patients who presented with a profile of suspicion for nonorganic hearing loss. Most cases were found, with the aid of DPOAE testing, to be nonorganic or to have nonorganic overlays to organic hearing loss.
  
  
  METHODS
  Interventions were diagnostic only.
  
  
  METHODS
  Observed audiometric findings and changes thereof.
  
  
  RESULTS
  Statistically significant decreases in thresholds occurred in subgroups of those cases deemed to be truly nonorganic in origin.
  
  
  CONCLUSIONS
  Especially considering test efficiency, the results support the inclusion of DPOAE analysis in the diagnostic management of the suspect-nonorganic patient.
