Ultrasound Guided Infratemporal Sphenopalatine Ganglion Supravoltage Versus Standard Voltage Pulsed Radiofrequency for Pain Alleviation in Chronic Refractory Migraine.

Ultrasound Guided Sphenopalatine Ganglion Supravoltage Versus Standard Voltage Pulsed Radiofrequency for Pain Alleviation in Chronic Refractory Migraine. Randomized Double Blind Study

Sponsor

Minia University

Enrollment

100 participants

Start Date

Mar 31, 2026

Study Type

INTERVENTIONAL

Conditions

Chronic Migraine, Headache

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.
