Ultrasound Guided Infratemporal Sphenopalatine Ganglion Supravoltage Versus Standard Voltage Pulsed Radiofrequency for Pain Alleviation in Chronic Refractory Migraine.
NCT: NCT07500558 · NOT_YET_RECRUITING
Brief 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.
