Trident Multi-tined Cannula for Cervical MBRFA Compared to the Conventional Cannula

The skin and superficial tissues will be anesthetized at each site with 1-2 mL of lidocaine. Prior to the ablation up to 2 mL of lidocaine may be used at each site to ensure adequate pain control during the ablation. Once in position, a radiofrequency ablation lesion will be made using a 30 second ramp-up time to a maximum temperature of 80 °C, followed by an additional 90 seconds at maximum temperature.
