Potencial evocado miogênico vestibular (VEMP)

Introduction:The Cervical Vestibular Myogenic Evoked Potential (cVEMP) has become a reliable and complementary measure of vestibular assessment. The investigation of vestibular disorders in the pediatric population is of great importance because they can have a series of repercussions throughout development. Purpose: To evaluate and analyze cVEMP responses in children and adolescents and compare them among gender, age, and ears. Methods: A cross-sectional study with 35 children and adolescents, 18 females and 17 males, aged 7 to 18 years, with normal hearing thresholds and no otoneurological complaints. All of them underwent a peripheral auditory evaluation and cVEMP. Results: In the analysis, it was observed that the mean latencies of P1 and N1 waves were, respectively, 15.92 ms and 24.32 ms, the amplitude P1/N1 of 36.91 µv and the symmetry ratio presented an average of 22.95%. No statistically significant differences were found comparing gender and ears. The same happened in the asymmetry index between genders. There were also no statistically significant differences in latencies and amplitudes. Conclusion: It was possible to measure values for latency and the amplitude of P1 and N1 waves in children and adolescents. In the present study, there was no statistically significant difference in the comparisons among ears, gender, and age.

Purpose To gather the parameters found in the cervical vestibular evoked myogenic potential (cVEMP) in children and adolescents with enlarged vestibular aqueduct syndrome (SAVA) and identify the possible changes, when compared to the values found in normal hearing people of the same age group. Research strategy Systematic review registered in the PROSPERO database, prepared through a search in virtual databases, based on the selected keywords. Selection criteria Included scientific articles available in full that reported the evaluation using cVEMP in the 0 and 18 years old group , with a diagnosis of SAVA, without restrictions of language and year of publication; Studies on patients with any disorder other than otoneurological ones and populations outside the proposed age range were excluded. Results 984 records were identified from the search in the databases consulted and 5 articles were selected. In a total of 133 patients who underwent cVEMP, the presence of a response was observed in most cases, with no significant difference in latencies, but with an increase in amplitude and a decrease in cVEMP thresholds. Conclusion The cVEMP test is recommended in the evaluation of children and adolescents with SAVA and the characteristics of increase in amplitude and decrease in thresholds can be used as clinical parameters in the identification of this syndrome, together with the patient’s clinical history and imaging exams. However, it is essential to carry out more studies with the cVEMP test, also in children and adolescents with SAVA, to better standardize the values found, in order to make the correct diagnosis.

Potencial miogênico evocado vestibular cervical em crianças e adolescentes com aqueduto vestibular alargado: revisão sistemática

RESUMO Objetivo Reunir os parâmetros encontrados no potencial miogênico evocado vestibular cervical (cVEMP) em crianças e adolescentes com síndrome do aqueduto vestibular alargado (SAVA) e identificar as possíveis alterações, quando comparados aos valores encontrados em normo-ouvintes da mesma faixa etária. Estratégia de pesquisa Revisão sistemática cadastrada na base PROSPERO, elaborada por meio de busca nos bancos de dados virtuais, a partir dos unitermos selecionados. Critérios de seleção Incluídos artigos científicos disponíveis na íntegra que relataram a avaliação com o uso do cVEMP na faixa etária entre 0 e 18 anos, com diagnóstico de SAVA, sem restrição de idioma e ano de publicação; excluídos estudos em paciente com algum distúrbio, outras patologias otoneurológicas e população fora da faixa etária estimada. Resultados Foram identificados 984 registros, a partir da pesquisa nas bases de dados consultadas e selecionados 5 artigos. Em um total de 133 pacientes que realizaram o cVEMP, foi observada presença de resposta na maioria dos casos, sem diferença significativa nas latências, mas com aumento na amplitude e diminuição nos limiares do cVEMP. Conclusão O teste cVEMP é recomendado na avaliação de crianças e adolescentes com SAVA e as características de aumento na amplitude e diminuição nos limiares podem ser utilizadas como parâmetros clínicos na identificação da referida síndrome, juntamente com a história clínica do paciente e os exames de imagem. No entanto, é imprescindível a realização de mais estudos com o exame cVEMP, ainda, em crianças e adolescentes com SAVA, para a melhor padronização dos valores encontrados, a fim de efetivar o diagnóstico correto.
