dc.description.abstract Electromyography is frequently used to measure the activity of masticatory muscles. It requires the precise setting of the electrodes, which demands the accurate location of the muscle to be evaluated. The purpose of this study was to investigate the accuracy of an external method to locate the buccinator muscle. Fifteen human cadavers were evaluated and planes were determined on the face using anatomic landmarks. An angle (a) was obtained at the intersection of these planes on the central point of buccinator muscle and measured with a protractor. The value of the angle allows locating the central point of buccinator muscle based on anatomic landmarks on the face. Statistical analysis of the collected data indicated an angle of 90º with 95% reliability, thus proving the efficacy of the proposed method. en

Esta análise exige a colocação precisa dos eletrodos, o que requer a localização exata do músculo a ser avaliado. O objetivo do presente estudo foi investigar a acurácia de um método externo para localização do músculo bucinador. Quinze cadáveres humanos foram avaliados e planos foram determinados na face utilizando-se pontos de referência anatômicos. Um ângulo (a) foi obtido na interseção desses planos no ponto central do músculo bucinador e foi medido com um transferidor. O valor do ângulo permite localizar o ponto central do músculo bucinador baseado nos pontos de referência anatômicos da face. A análise estatística dos dados obtidos indicou um ângulo de 90º com 95% de confiabilidade, confirmando dessa forma a eficácia do método proposto. pt
