“…The results of the present study showed the lack of asymmetry between the ears in the evaluated groups, in contrast with a study that found higher wave V amplitude and lower BAEP wave latency in the right ear, suggesting that the right ear is favored in auditory processing along the auditory pathway (15) . Our results are consistent with the current literature, concluding that the maturational process along the central auditory pathways occurs simultaneously in both ears (16)(17)(18)(19) . During the neonatal period, the comparison between the AGA and SGA groups (Table 1) showed no differences, except for wave I, which was significantly more precocious in the AGA group.…”

“…The preparation of all NBs for BAEP testing was conducted as follows: prior cleaning of the skin with abrasive paste and fixation of Kendal® Meditrace-200 disposable pediatric electrodes on the forehead (Fpz) and the right and left mastoids (M 2 and M 1 ), according to the International Electrode Systems standards (IES [10][11][12][13][14][15][16][17][18][19][20]. The acoustic stimulus was presented by a pair of ER-3A insertion earphones, eliciting the responses.…”

Purpose: To monitor the auditory pathway maturation of infants born small for gestational age (SGA), according to body proportionality, in the first six months of life. Methods: Brainstem auditory-evoked potential (BAEP) was performed during the neonatal period and at six months of life in 59 infants born small for gestational age; among them, 35 were born asymmetrical (SGA-A), and 24 were born symmetrical (SGA-S).The results were compared to those of 59 infants considered appropriate for gestational age (AGA). Results: The term and pre-term SGA-A and SGA-S infants showed a significant auditory maturation process

“…So, five studies concluded with their investigations that there are changes in neural development in the SGA population influencing the maturation process of the auditory pathway, resulting in abnormalities in the BAEP test. 10,12,16,26,31 On the other hand, five studies 15,25,[27][28][29] did not evidence differences between the SGA and AGA groups. These disparities among the results can be justified by some peculiarities among the studies, such as the population studied, differences of methodologies, the type of study used, and the small number of participants in some of the studies.…”

“…The prolongation of wave V latency can have different meanings, such as the maturation process of central auditory pathways or by peripheral conductive alteration, for instance. 30 All studies used in our review only included in their investigations full-term participants with normal hearing, who presented the bilateral presence of otoacoustic emissions and a type A tympanometry curve 10,16,25,27,31 and were free of risk factors, known for affecting hearing function. 15,26,28,29 Therefore, the risk factor studied that could affect hearing function was the SGA factor.…”

Introduction Factors of intrauterine growth restriction have been responsible for the births of full-term babies small for their gestational age (SGA). Scientific evidence points that this restriction can cause changes in the neural maturation process. Objectives To analyze the absolute latencies and interpeak intervals of brainstem auditory evoked potential waves in full-term and SGA children to investigate whether there are changes of neural maturation in this population. Data Synthesis The search for articles that reported the assessment of brainstem auditory evoked potential in SGA newborns compared with a control, appropriate for their gestational age, both born full-term, for the entire period available in the database research until October 31, 2021 was performed based on the MEDLINE/PubMed Central and on the Latin America and the Caribbean Health Sciences Literature and Virtual Health Library electronic databases. A total of 311 studies were found in the database research. Out of this total, 10 studies were included in the review, 5 of which were eligible for the meta-analysis, involving a total of 473 participants of both genders, with 193 participants belonging to the study group and 280 to the control group. Differences between the groups were only observed in the absolute latency of wave V (95% confidence interval [CI]: 0.02–0.15; p < 0.01). Conclusion The SGA condition is responsible for the appearance of brainstem neural conduction dysfunction measured by the brainstem auditory evoked potentials, probably by the maturation process of the auditory pathway of this population.

“…Other factor that confirms the likelihood of greater alterations in infants born at term and small for gestational age would be the brain vulnerability due to the impact caused by intrauterine nutritional restriction; therefore, the degree of neurological impairment of a SGA child will depend on the time, severity and duration of the insult (1) . In addition, T/SGA infants, when compared to T/AGA infants, are three times more likely to develop morbidities, possibly because they have a different maturation rhythm of the auditory pathway when compared to AGA children (1,17,18) .…”

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.
