Abstract
Purpose: To characterize cortical auditory evoked potentials in children with speech sound disorders, to determine whether there are differences between the results of children with speech sound disorders and those with typical development, and to present reference ranges for the observed values.
Methods: This is a cross-sectional, observational, and analytical study involving 40 assessments (20 in the Control Group and 20 in the Study Group). The latencies and amplitudes of the P1N1P2N2 complex were analyzed in both groups. Comparisons of these values between groups were made, and reference intervals were established.
Results: No statistically significant differences were found in the P1N1P2N2 latency and amplitude values between the study and control groups. However, children with speech sound disorders exhibited increased latencies in all analyzed components.
Conclusion: The analysis of cortical auditory evoked potentials in children with speech sound disorders and typical development showed adequate morphology of the P1, N1, P2, and N2 waves, allowing for the establishment of reference values for both groups. Although no statistically significant differences were observed between the children with speech sound disorders and typically developing children, the former group exhibited increased latencies across all components of the cortical potential.
