ABSTRACT
Introduction: The complications of diabetes mellitus type 1 (1DM) can affect the auditory pathway.
Objectives: To investigate the auditory, peripheral and central pathways and the presence of
neuroauditic complaints in children and adolescents with 1DM. Methodology: 101 individuals
participated in this study, 50 with 1DM (GE) and 51 without (CG). All of them responded to an
audiological interview and performed threshold tone audiometry, immitance testing, amplitude
distortion product otoacoustic emissions (DPOAE), evaluation of the inhibitory effect of the efferent
pathway, tests the auditory brainstem response (ABR) and cognitive potential (PEALL). Results:
There was a significant statistical relationship between the groups regarding hearing complaints of:
dizziness (p=0,031), tinnitus (p= 0,020), difficulties in understanding speech in noise (p=<0,001),
difficulties in atention (p=0,025), memory problems (p= 0,002), distraction in noise (p= 0,007),
difficulties in understanding television (p=0,026) and telephone (p=0,042). The acoustic reflex
thresholds were altered in participants with diabetes at frequencies of 500 Hz (p = 0.005 / 0.003), 1
kHz left ear (p = 0.013) and 2 kHz (p = 0.036 / 0.008). In the DPOAE investigation, there was no
statistical significance. In the analysis of the inhibitory effect, a statistical difference was observed
in the left ear in the frequencies of 4 kHz (p = 0.001) and 8 kHz (p = 0.003). There was no association
between inhibitory effect, acoustic reflex, age of diagnosis, disease duration and metabolic control
in both ears. As for the association between ABR and metabolic variables, there was a positive
correlation between disease duration and metabolic control between the V wave and the us interpeak
intervals, I-III and I-V. Regarding the cognitive potential, there was no statistical significance
between the groups, and between diabetic participants and metabolic variables. Conclusion: The
reduction of the inhibitory effect, altered acoustic reflex and auditory evoked potentials in children
and adolescents with 1DM suggest that the peripheral and central auditory system could early be
compromised.
