Abstract(s)
A Síndrome Dolorosa Miofascial é um quadro de dor regional caracterizado pela presença de pontos gatilho nos músculos. Os pontos gatilhos quando ativos provocam a dor referida, tensão muscular e incapacidade funcional. A dor miofascial pode afetar os músculos da mastigação e o seu tratamento pode ser realizado de duas formas: através de técnicas não invasivas com terapêutica farmacológica, exercícios e alongamentos musculares, goteiras e estimulação elétrica, e técnicas invasivas como agulhamento seco, a acupuntura, a injeção de anestésicos locais e a infiltração com outras substâncias diferenciadas como a toxina botulínica. Esta revisão narrativa tem como objetivo avaliar o sucesso terapêutico da aplicação da toxina botulínica na região orofacial. A toxina botulínica tem-se mostrado promissora no tratamento de pontos gatilho na região orofacial, mas mais estudos randomizados e de longa duração devem ser realizados para avaliar a sua eficácia a longo prazo.
Myofascial Pain Syndrome is a condition of regional pain characterized by the presence of trigger points in the muscles. When trigger points are actived cause referred pain, muscle tension and functional disability. Myofascial pain can affect the chewing muscles and the treatment can be performed in two ways: through non invasive pharmacological therapy, muscle stretching and exercises, dripping and electrical stimulation, and invasive techniques such as dry needling, acupuncture, injection of local anesthetics and infiltration with other differentiated substances such as botulinum toxin. This narrative review aims to evaluate the therapeutic success of botulinum toxin application in the orofacial region. Botulinum toxin has been shown to be promising in the treatment of orofacial trigger points, but further randomized and long-term studies should be conducted to assess its long-term efficacy.
