Glossopharyngeal Neuralgia
Glossopharyngeal neuralgia is a condition that is associated with paroxysmal pain that is similar to, though less intense than, the pain of TN. The location of the trigger zone and pain sensation follows the distribution of the glossopharyngeal nerve, namely, the pharynx, posterior tongue, ear, and infraauricular retromandibular area. Pain is triggered by stimulating the pharyngeal mucosa during chewing, talking, and swallowing.

The management of glassopharyngeal neuralgia involves glassopharyngeal nerve block which is used both for its diagnostic and therapeutic value. If pain is recurrent, Pulsed RF of glassopharyngeal nerve is done under fluoroscopic guidance and local anaesthesia.
