Pharmacological management is the first choice for treatment of the trigeminal neuralgia patients; however, if this mode of treatment fails a minimally invasive procedure should be performed. One of the most commonly used procedures is conventional radiofrequency lesioning of the Gasserian ganglion. Despite its popularity and success rate, this technique has disadvantages such as diminished corneal reflex, masseter weakness, numbness and anesthesia dolorosa. As a result, many studies have been conducted in an attempt to find a better method of treating trigeminal neuralgia. We report here a case of a trigeminal neuralgia patient that was treated with pulsed radiofrequency lesioning of the supraorbital and supratrochlear nerve due to pain in the frontal head that was refractory to the pharmacological treatments. Following the procedure, the Visual Analogue Scale score for pain decreased to 1-2/10 and the pain relief persisted for 7 months. These results indicate that pulsed radiofrequency treatment of the peripheral nerve may be useful for trigeminal neuralgia patients that do not respond to pharmacological treatments.

A cluster headache is characterized by the occurrence of strictly unilateral and periocular pain with no side shift and ipsilateral oculofacial autonomic symptoms such as conjunctival injection, lacrimation, rhinorrhea and miosis. Cluster headache involves the activation of parasympathetic nerve structures located within the sphenopalatine ganglion, and blockade of the sphenopalatine ganglion has been shown to be effective at the treatment of cluster headaches that are resistant to conventional therapy. Herein, we describe a case of a 50-year-old male with a cluster headache that could not be controlled by conventional treatments who showed improvement after being treated with sphenopalatine ganglion pulsed radiofrequency.
