migrânea crônica). As crises migranosas de forte inten-
sidade diminuíram significativamente.(

Não há evidências sobre que substância injetada
seria superior no tratamento dos pontos gatilho asso-
ciados às cefaleias primárias. Segundo consenso de
especialistas publicado recentemente, se deve dar
preferência aos anestésicos locais (lidocaína a 1% ou
ropivacaína a 0,5%). A infiltração deve ser feita em
pacientes com PG miofasciais na cabeça ou no pescoço
cuja palpação reproduza a cefeleia do paciente,
sugerindo-se uma frequência de aplicações de uma vez
ao mês.

CONCLUSÕES
1 - Pacientes com cefaleia têm mais pontos-gatilho
miofasciais que pacientes sem cefaleia.
2 - Os pontos-gatilho miofasciais podem contribuir
para o processo de sensibilização central e cronificação
da cefaleia.
3 - Em pacientes com migrânea ou cefaleia tipo
tensional com pontos-gatilho miofasciais cuja palpação
reproduza a cefaleia do paciente, se pode considerar a
infiltração dos mesmos com anestésicos locais.
