Descrição
Resumo:The Auditory Evoked Middle Latency Response is one of the most promising objective tests in audiology and in revealing brain dysfunction and neuro-audiologic findings. The main advantages of its clinical use are precision and objectivity in evaluating children. This study aimed to analyze the auditory evoked middle latency response in two patients with auditory processing disorder and relate objective and behavioral measures. This case study was conducted in 2 patients (P1 = 12 years, female, P2 = 17 years old, male), both with the absence of sensory abnormalities, neurological and neuropsychiatric disorders. Both were submitted to anamnesis, inspection of the external ear canal, hearing test and evaluation of Auditory Evoked Middle latency Response. There was a significant association between behavioral test and objectives results. In the interview, there were complaints about the difficulty in listening in a noisy environment, sound localization, inattention, and phonological changes in writing and speaking, as confirmed by evaluation of auditory processing and Auditory Evoked Middle Latency Response. Changes were observed in the right decoding process hearing in both cases on the behavioral assessment of auditory processing; auditory evoked potential test middle latency shows that the right contralateral via response was deficient, confirming the difficulties of the patients in the assignment of meaning in acoustic information in a competitive sound condition at right, in both cases. In these cases it was shown the association between the results, but there is a need for further studies with larger sample population to confirm the data.
