Standard Pulsed Radiofrequency Versus Supervoltage Pulsed Radiofrequency

Status Recruiting

Clinical Trial Summary

The aim of this study is to evaluate the safety and efficacy of supervoltage pulsed radiofrequency glossopharyngeal nerve therapy versus standard pulsed radiofrequency in reduction of oropharyngeal cancer pain, through Visual analog scale score reduction.

Clinical Trial Description

The glossopharyngeal nerve is the 9th cranial nerve. It has motor, sensory and parasympathetic function like trigeminal and facial nerves. It has its origin in the medulla oblongata and exits the skull via the jugular foramen, close to vagus and accessory nerves, together with the internal carotid artery and sympathetic nerves and terminates in the pharynx between the superior and middle pharyngeal constrictors, splitting into its terminal branches - lingual, pharyngeal, and tonsillar. Glossopharyngeal neuralgia is an extremely uncommon occurrence and accounts for only 0.2%-1.3% of the cases with facial pain. It usually affects the male individuals above 50-year age, and the reported incidence of glossopharyngeal neuralgia is roughly 0.8 per 100,000 persons per year. As per ICHD-3 (International Classification of Headache Disease- 3) classification, glossopharyngeal neuralgia is a disease characterized by an episodic unilateral pain, with sharp and stabbing in character, with sudden onset and cessation, in the glossopharyngeal nerve distribution (jaw angle, ear, tonsillar fossa and the base of the tongue). It also affect the pharyngeal and auricular branches of the vagus nerve. Pain is commonly aggravated by coughing, talking, and swallowing. Pain in glossopharyngeal neuralgia has a relapsing and remitting pattern. Vaso glossopharyngeal neuralgia may be associated with life-threatening cardiovascular features- syncope, hypotension, cardiac arrhythmias, in contrast to trigeminal neuralgia ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
