Long-term Follow-up of the Effectiveness and Safety of High-voltage Pulsed Radiofrequency Treatment for Infraorbital Neuralgia: A Retrospective Study.

Infraorbital neuralgia is a refractory facial pain that may cause various psychological disorders. There is no optimal treatment for infraorbital neuralgia because few relevant studies have been conducted. Pulsed radiofrequency (PRF) is a minimally invasive procedure that has been proven effective in treating trigeminal neuralgia and other painful diseases. Our previous study demonstrated that high-voltage PRF was effective in patients with infraorbital neuralgia. However, there is little literature on the long-term follow-up of infraorbital neuralgia treated with high-voltage PRF with a large sample size.
