Summary

Introduction: The Vestibular Evoked Myogenic Potential (VEMP) is a promising test for the evaluation of the cholic descending vestibular system. This reflex depends of the integrity from the saccular macula, from the inferior vestibular nerve, the vestibular nuclei, the vestibule-spinal tract and effectors muscles.

Objective: Perform a systematic review of the pertinent literature by means of database (COCHRANE, MEDLINE, LILACS, CAPES).

Conclusion: The clinical application of the VEMP has expanded in the last years, as goal that this exam is used as complementary in the otoneurological evaluation currently used. But, methodological issues must be clarified. This way, this method when combined with the standard protocol, can provide a more widely evaluation from the vestibular system. The standardization of the methodology is fundamental criterion for the replicability and sensibility of the exam.

Resumo

Introdução: O Potencial Evocado Miogênico Vestibular (VEMP) é um teste promissor para a avaliação do sistema vestíbulo-cólico descendente. Este reflexo depende da integridade da mácula sacular, do nervo vestibular inferior, dos núcleos vestibulares, das vias vestíbulo-espinhais e do músculo efetor.

Objetivo: Realizar revisão sistemática de literatura pertinente por meio de bases de dados (COCHRANE, MEDLINE, LILACS, CAPES).

Conclusão: A aplicação clínica do VEMP expandiu-se nos últimos anos, com o objetivo de que este exame seja utilizado como complementar na avaliação otoneurológica atualmente utilizada. Porém, questões metodológicas devem ser esclarecidas. Dessa forma, este método, quando combinado com o protocolo padrão, poderá fornecer uma avaliação mais abrangente do sistema vestibular. A padronização da metodologia é fundamental critério para a replicabilidade e sensibilidade do exame.
