Why carry out this study?

Zoster-associated pain (ZAP) is a neuropathic pain syndrome characterized by complex mechanisms that cause severe discomfort and a high incidence of complications, leading to significant physical and psychological distress for patients.

Current treatment approaches for ZAP involve early administration of antiviral medications, analgesics, and various minimally invasive interventions.

While radiofrequency therapy has gained popularity as a treatment for ZAP, there remains a lack of standardization regarding its parameters and therapeutic objectives, which necessitates further investigation. This paper aims to review the recent advancements in this field.

What was learned from the study?

The application of high-voltage, long-duration pulsed radiofrequency and radiofrequency thermocoagulation therapy has shown improved therapeutic outcomes, but attention should be given to potential intraoperative and postoperative complications.

Both intercostal nerves at the angulus costae and extracranial targets have demonstrated effectiveness as targets for radiofrequency therapy while maintaining a high level of safety.

Combined treatments utilizing multiple mechanisms are currently gaining recognition and popularity.
