Abstract(s)
A dor miofascial nos músculos da mastigação é uma disfunção temporomandibular de origem muscular. Caracteriza-se pela presença de pontos gatilho e por mialgia, com dor além da região de palpação, mas que pode aparecer dentro dos limites do músculo ou manifestar-se como dor referida numa outra região orofacial.
A toxina botulínica é uma neurotoxina com ação neuroparalisante, utilizada a nível da cabeça e pescoço em situações de desordens temporomandibulares, distonias, espasmo hemifaciais, bruxismo, sialorreia, dor de cabeça e, também, em tratamentos cosméticos.
Esta revisão narrativa da literatura teve como objetivo fundamental avaliar a eficácia da aplicação da toxina botulínica no tratamento da dor miofascial orofacial.
A literatura disponível demonstra que a toxina botulínica é uma opção viável no tratamento da dor miofascial orofacial, mas que são necessários mais estudos - randomizados, duplamente cegos e controlados -, com grupos de estudo maiores para validar o efeito no tempo da terapêutica, bem como de múltiplas aplicações.
Myofascial pain of masticatory muscles is a temporomandibular dysfunction with muscular origin. It is characterized by the presence of trigger points and myalgia, with pain beyond the region of palpation, which can be located inside the borders of the muscle or referred in another orofacial region. Botulinum toxin is a neurotoxin with neuroparalizing action used in the head and neck region in cases of temporomandibular dysfunctions, dystonias, hemifacial spasms, bruxism, sialorrhea, headaches, and also in cosmetic treatments. The aim of this narrative review was to evaluate the efficacy of the application of botulinum toxin in the treatment of orofacial myofascial pain. The literature available shows that botulinum toxin is a viable option for treatment of myofascial pain, although there is still the need for more studies, randomized, double blinded, controlled and with larger study groups, in order to validate the future effects of the therapy, as well as multiple applications.
