Braite N, et al. - In this investigation involving 101 children and adolescents, researchers ascertained if T1DM could affect the efferent auditory system by examining the connection between the activation of the medial olivocochlear reflex with disease duration, metabolic control and age at the time of diagnosis. When compared with the group without the disease, the candidates with T1DM presented changed AR (increased and/or absent) at all the frequencies in both ears. In both ears at all the frequencies, no differences between the DPOAE amplitudes of the people with and without T1DM were observed. There was no connection between the hearing complaints and the audiological measurements obtained and disease time, metabolic control and age at the time of diagnosis. In patients with T1DM, the presence of early auditory dysfunction of the efferent pathway was suggested.
