title: Long-term recovery and no recovery from the auditory deprivation effect with binaural amplification: six cases.
abstract: Six subjects who developed individually significant auditory deprivation effects associated with monaural amplification were tracked for 6.2 to 15.1 years from the time of their initial hearing aid fitting. Each subject received binaural hearing aids after the auditory deprivation effect became apparent and used binaural amplification for at least 4 years. The findings corroborate and expand upon existing case reports. Several general configurations of recovery and no recovery following the introduction of binaural amplification were identified: (1) cases in which auditory deprivation effects developed within about 2 years and recovered completely within about 2 years of binaural use; (2) cases with significant but incomplete recovery; and (3) cases in which the auditory deprivation effect took several years to develop and did not recover following several years of binaural amplification. Clinical implications of the results are proposed.
