Auditory processing in unilateral hearing loss: case report.
Unilateral hearing loss represents great risk to academic backwardness, communication, social development, and also to auditory processing. Thus, the aim of this study was to evaluate the auditory abilities of localization, closing, figure-ground, temporal resolution, and simple temporal ordering in a male 17-year-old individual diagnosed with profound unilateral sensorineural hearing loss of idiopathic etiology, without other alterations. The evaluation process consisted on the application of a checklist, and the conduction of conventional clinical audiological evaluation (pure-tone audiometry, logoaudiometry, and tympanometry), and of monotic (ipsilateral SSI, Filtered speech test) and diotic (Sound localization, Auditory memory for verbal and non-verbal sounds, AFT-R) auditory processing test. Results showed alteration only in the sound localization test. No complaints were reported regarding the abilities of sound localization, attention, discrimination, and comprehension. In this case study, the profound unilateral sensorineural hearing loss did not seem to restrict the development of the auditory processing abilities evaluated, except for the localization of the sound source.
