Cluster Headache, Facial Pain, Postherpetic Neuralgia, Trigeminal Neuralgia
Conditions
Brief summary
The purpose of this study is to investigate the incidence of intravascular injection during trigeminal nerve blocks.
Detailed description
The patients who already scheduled for trigeminal nerve blocks will be randomized in a 1:1 ratio to tuohy needle group or quincke needle group after being informed about the study.
Interventions
PROCEDUREtrigeminal nerve block
Trigeminal nerve or branch block using 22 gauge Quincke or Tuohy needle under fluoroscopic guidance.
