Resumo: | Twenty normal individuals were submitted to facial nerve electroneurography using different techniques in order to determine the most accurate to obtain the latencies and amplitudes of the compound muscle action potentials (CMAP) of the facial muscles. First of all it was determined in which muscle or muscle group highest amplitude CMAP could be recorded with the lowest variability between sides and in test-retest. Different techniques were studied in order to determine which could give the best results. This was shown to be an arrangement of bipolar surface electrodes fixed to a plastic bar. The records with higher amplitude where obtained from the nasolabial fold muscles. Therefore 65 normal volunteers were examined using this technique and recording the potentials obtained over the nasolabial fold muscles. Normal values were determined (latency lower than 4.5 ms and amplitude larger than 2 mV - 95% confidence limits). |

Inicialmente determinou-se em qual músculo ou grupo muscular registra-se CMAP com maior amplitude e menor variabilidade entre lados e entre testes, assim como determinou-se qual técnica proporcionou melhores resultados. A que mostrou melhores resultados foi realizada com eletrodos de superfície bipolares de discos fixos em barra de plástico e os melhores registros foram obtidos nos músculos do sulco nasolabial. A seguir 65 voluntários normais foram estudados com esta técnica registrando-se os potenciais nos músculos do sulco nasolabial e foram determinados os valores normais para a latência (menor que 4,5 ms) e amplitude (acima de 2 mV).Federal University of São Paulo Escola Paulista de Medicin Clinical Neurophysiology LaboratoryUNIFESP, Escola Paulista de Medicin 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]Juliano, Yara [UNIFESP]2015-06-14T13:24:32Z2015-06-14T13:24:32Z1996-09-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion393-396application/pdfhttp://dx.doi.org/10.1590/S0004-282X1996000300005Arquivos de Neuro-Psiquiatria.
