Glossopharyngeal Neuralgia

External Ids:

NINDS: ⁵² Glossopharyngeal neuralgia (GN) is a rare pain syndrome that affects the glossopharyngeal nerve (the ninth cranial nerve that lies deep within the neck)  and causes sharp, stabbing pulses of pain in the back of the throat and tongue, the tonsils, and the middle ear.  The excruciating pain of GN can last for a few seconds to a few minutes, and may return multiple times in a day or once every few weeks.  Many individuals with GN relate the attacks of pain to specific trigger factors such as swallowing, drinking cold liquids, sneezing, coughing, talking, clearing the throat, and touching the gums or inside the mouth.  GN can be caused by compression of the glossopharyngeal nerve, but in some cases, no cause is evident.  Like trigeminal neuralgia, it is associated with multiple sclerosis.  GN primarily affects the elderly.

MalaCards based summary: Glossopharyngeal Neuralgia, also known as glossopharyngeal nerve diseases, is related to glossopharyngeal nerve disease and trigeminal neuralgia. An important gene associated with Glossopharyngeal Neuralgia is KANTR (KANTR Integral Membrane Protein). The drugs Immunoglobulins and Antibodies, Blocking have been mentioned in the context of this disorder. Affiliated tissues include tongue, cortex and medulla oblongata, and related phenotypes are depression and anxiety

Orphanet: ⁵⁸ A rare cranial neuralgia characterized by paroxysmal, usually unilateral stabbing pain within the sensory distributions of the auricular and pharyngeal branches of the glossopharyngeal and sometimes the vagus nerve (i. e. the posterior part of the tongue, the tonsillar fossa, oropharynx, larynx, angle of the mandible, and/or ear). The attacks last seconds to minutes with intervals between the paroxysms ranging from a few minutes to a few hours, and appear in clusters lasting weeks to months, again with irregular intervals in between. Pain attacks are usually triggered by a specific stimulus but may also occur spontaneously. The condition can sometimes be associated with bradycardia, syncope, seizures, and even asystole, and is then termed vagoglossopharyngeal neuralgia.

GARD: ¹⁹ Glossopharyngeal neuralgia is a disorder that is associated with repeated episodes of severe pain in the tongue, throat, ear, and tonsils. These areas are all connected to the ninth cranial nerve, also called the glossopharyngeal nerve. Episodes of pain may last from a few seconds to a few minutes and usually occur on one side of the face. The pain may be triggered by swallowing, speaking, laughing, chewing, or coughing. Glossopharyngeal neuralgia is thought to be caused by irritation of the glossopharyngeal nerve, but the exact cause of the irritation is sometimes unknown. Laboratory and imaging tests can be used to diagnose the disorder and rule out serious underlying problems.
