Resumo: To determine the variability of the abnormalities found in the electroneurography (ENG) of the facial nerve in cases of Bell's palsy during the initial two week period was one of the objectives of the authors. A second one was to investigate the value of ENG as a tool to determine an early prognosis of recovery utilizing two different methods. In the first one the amplitude of the compound muscular action potential (CMAP) obtained on the paralyzed side was compared to this potential on the opposite (normal) side. The second method compared the CMAP on the paralyzed side to normal standardized data from normal individuals. A group of 33 patients with Bell's palsy was followed until total recovery or for at least 4 months, if the recovery was not achieved earlier. It was observed that amplitude of the CMAP become stable towards the sixth day of palsy and this is a good time to establish the prognosis. Another conclusion is that both methods were equivalent to determine the prognosis in Bell's palsy.

O primeiro método compara a amplitude do potencial de ação muscular composto obtido no lado paralisado com o lado normal e o segundo método compara o potencial de ação muscular composto obtido no lado paralisado com valores normativos. Um grupo de 33 pacientes com paralisia de Bell foi seguido até a recuperação total ou pelo menos por quatro meses nos casos em que não houve recuperação. Observou-se que a amplitude do potencial de ação muscular composto estabiliza-se em torno do sexto dia e que este é um bom momento para se realizar o exame e se estabelecer um prognóstico. Outra conclusão é que ambos os métodos são equivalentes para determinação prognóstica.Universidade Federal de São Paulo (UNIFESP), Escola Paulista de Medicina (EPM) Clinical Neurophysiology LaboratoryUNIFESP, EPM, Clinical Neurophysiology LaboratorySciELOAcademia Brasileira de Neurologia - ABNEUROUniversidade Federal de São Paulo (UNIFESP)Medeiros, Jovany Luis Alves de [UNIFESP]Nobrega, João Antonio Maciel [UNIFESP]Andrade, Luiz Augusto Franco de [UNIFESP]Novo, Neil Ferreira [UNIFESP]2015-06-14T13:24:32Z2015-06-14T13:24:32Z1996-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion397-401application/pdfhttp://dx.doi.org/10.1590/S0004-282X1996000300006Arquivos de Neuro-Psiquiatria.
