Ultrasound-guided pulsed radiofrequency treatment for postherpetic neuralgia of supraorbital nerve: A case report

ABSTRACT

Pulsed radiofrequency treatment has an analgesic effect by neuromodulation of the central pain pathway without neural injury. However, lack of knowledge regarding the exact mechanism on neuropathic pain makes the use of pulsed radiofrequency treatment controversial. Here, we describe a case of satisfactory pain relief after ultrasound-guided pulsed radiofrequency treatment in a patient with supraorbital herpetic pain refractory to medication. This case indicates the potential of ultrasound-guided pulsed radiofrequency treatment in patients with postherpetic supraorbital neuralgia.
