“…The results of this study (Table 5) showed that the latency means of the component P1 were within the normality range (between 127 and 151 msec), in agreement with the results of studies conducted earlier (22)(23)(24) , although slightly higher than in other studies, which found, for the same age group, P1 responses between 87 and 126 msec (24,25) . The mean values found for N1 in the present study (between 212 and 243 msec) were also higher than in a previous study with children in the same age group, where the values ranged from 131 to 158 msec (25) .…”

RESUMO Objetivo Monitorar o sistema auditivo central de crianças nascidas pequenas para a idade gestacional, por meio da avaliação eletrofisiológica da audição, para verificar a ocorrência de eventuais disfunções neurais nesse sistema. Métodos Estudo longitudinal, cuja casuística foi composta por 23 crianças distribuídas em quatro grupos: 1) grupo de quatro crianças nascidas pequenas para a idade gestacional e a termo; 2) grupo de sete crianças nascidas pequenas para a idade gestacional e pré-termo; 3) grupo de quatro crianças nascidas com peso adequado para a idade gestacional e a termo; 4) grupo de oito crianças nascidas adequadas para a idade gestacional e pré-termo, cuja idade ao final da pesquisa foi de 3 anos (variação entre 34 e 39 meses). O critério de inclusão foi presença bilateral de emissões otoacústicas transientes. Todas as crianças foram submetidas ao potencial evocado auditivo de tronco encefálico ao nascimento, aos 6 meses e aos 3 anos de idade e à pesquisa do potencial evocado auditivo de longa latência aos 3 anos. Resultados crianças nascidas pequenas para a idade gestacional e a termo tiveram maior ocorrência de alterações, em relação aos demais grupos, com aumento da latência das ondas III e V e interpicos I-III e I-V. Todas apresentaram resultados normais no potencial evocado auditivo de longa latência. Conclusão Crianças nascidas pequenas para a idade gestacional e a termo apresentam disfunções na condução neural no tronco encefálico e devem ser consideradas de risco para alterações do desenvolvimento das habilidades auditivas necessárias para garantir qualidade de processamento da informação acústica.

“…The component P1 of LLAEOs was established as a biological marker to assess maturation of the central auditory system in children for being a robust positive response easily identifiable, which occurs between 100-300 msec after stimulus, depending on the child's age (22)(23)(24) .…”

“…In this study, it was possible to assess central auditory maturation during the first 3 months of term and preterm infants through CAEP P1 for different tonal stimuli. This potential is a neurophysiological biomarker that is feasible in the study of typical and atypical auditory development in children (7,10,21). A decrease in latency values was observed for all frequencies used to evoke the P1 component from the first to the third month of life in both groups.…”

“…Therefore, the electrophysiology of hearing is of great importance in the stages of child development because it allows clinicians to understand and monitor the maturation of auditory structures (7). Although studies of brainstem auditory-evoked potential are of great value for understanding these conditions and providing evidence of differences in the maturational pattern of preterm births (6), the use of long-latency auditory-evoked potential allows the verification of conditions of the central auditory system, making this evaluation an additional tool in the study of auditory maturation.…”

“…Although CAEP includes P1, N1, and P2 components, N1 and P2 are not considered to be reliable until 7 years of age [2]. The latency of P1 was reported to be measured within 300 milliseconds (ms) in newborns and infants, with a rapid decrease down to 200 ms at 2 years of age and maintained at 100 ms in adulthood [3][4][5]. This change represents the increased speed of synaptic propagation of the central auditory pathways [6].…”

The aim of this study was to determine the age-related latency interval of P1 latencies of children with normal hearing, and to evaluate the P1 latency changes after surgery in children who underwent cochlear implantation. Materials and methods: We evaluated 60 children with normal hearing and 16 children with cochlear implants aged 0-6 years using cortical auditory evoked potentials. P1 latencies were measured only once in the children with normal hearing, and on the postoperative first day, and the first, third, and sixth postoperative months in the children with cochlear implants. Results: There was a statistically significant decrease in the P1 latencies as the age increased in children with normal hearing (P < 0.001). It was determined that when the external partof the cochlear implant was applied, the P1 latencies of children with cochlear implants were significantly longer than those of age-matched children with normal hearing (P < 0.001). This difference disappeared in 10 children with implants at the third and sixth months, but significant differences remained in 6 children. Conclusion: P1 latency could be used as an objective tool to evaluate the normal development of auditory pathways, and may be helpful in the effective programming of children undergoing cochlear implantation.
