Summary

* PRF performed on the sphenopalatine ganglion level under ultrasound guidance.
* Standard voltage PRF parameters: 45 V, 5 Hz frequency, 5 ms pulse width, 360 seconds duration, electrode temperature ≤42°C.
* Supravoltage PRF parameters: Higher voltage than standard (e.g., 60-70 V), with same frequency, pulse width, and duration, maintaining temperature ≤42°C to avoid nerve damage.

Conditions

  • Chronic Migraine, Headache
