What is the treatment for glossopharyngeal neuralgia?

Medications. Our first-line treatment is medication. The drugs that work best at relieving GPN pain are anticonvulsant medications, such as carbamazepine (Tegretol), gabapentin (Neurontin), phenytoin (Dilantin), pregabalin (Lyrica), oxcarbazepine (Trileptal) and baclofen (Lioresal).

Is glossopharyngeal neuralgia life threatening?

Glossopharyngeal neuralgia is life-threatening condition because it is associated with cardiac arrest, hypotension, syncope and weight loss. Treatment with carbamazepine is affected in patients with cardiovascular manifestations.

What does glossopharyngeal supply?

The glossopharyngeal nerve carries sensory, efferent motor, and parasympathetic fibers. Its branches consist of tympanic, tonsillar, stylopharyngeal, carotid sinus nerve, branches to the tongue, lingual branches, and a communicating branch to cranial nerve X (vagus nerve).

Where does cranial 9 exit?

The glossopharyngeal nerve (/ˌɡlɒsoʊfəˈrɪn(d)ʒiəl, -ˌfærənˈdʒiːəl/), known as the ninth cranial nerve (CN IX), is a mixed nerve that carries afferent sensory and efferent motor information. It exits the brainstem out from the sides of the upper medulla, just anterior (closer to the nose) to the vagus nerve.

How is Glossopharyngeal neuralgia diagnosed?

Diagnosis of Glossopharyngeal Neuralgia

For the test, a doctor touches the back of the throat with a cotton-tipped applicator. If pain results, the doctor applies a local anesthetic to the back of the throat. If the anesthetic eliminates the pain, glossopharyngeal neuralgia is likely.

What is 6th cranial nerve?

It’s also known as the abducens nerve. This condition causes problems with eye movement. The sixth cranial nerve sends signals to your lateral rectus muscle. This is a small muscle that attaches to the outer side of your eye. When this muscle contracts, your eye moves away from your nose.

What kind of nerve is the vagus nerve?

vagus nerve, also called X cranial nerve or 10th cranial nerve, longest and most complex of the cranial nerves. The vagus nerve runs from the brain through the face and thorax to the abdomen. It is a mixed nerve that contains parasympathetic fibres.

Who treats glossopharyngeal neuralgia?

If the pain requires further evaluation, a neurologist or a neurosurgeon may be recommended. The diagnosis of neuralgia is made after carefully assessing the patient’s symptoms. If glossopharyngeal neuralgia is suspected, the doctor will attempt to trigger an episode by touching the back of the throat with a swab.

Can acid reflux cause glossopharyngeal neuralgia?

Irritation of the respiratory epithelium by gastric acid stimulates the glossopharyngeal and vagus nerves, producing ear pain. Throat cancer could be responsible for secondary glossopharyngeal neuralgia, but could also induce referred ear pain by irritation of the superior laryngeal branch of the vagus nerve.

Can neuralgia be cured?

There is no cure for neuralgia, but treatment can help improve your symptoms. Some types of neuralgia improve over time. More research is being done to develop better treatments for neuralgia.

What triggers glossopharyngeal neuralgia?

Possible causes for this type of nerve pain (neuralgia) are: Blood vessels pressing on the glossopharyngeal nerve. Growths at the base of the skull pressing on the glossopharyngeal nerve. Tumors or infections of the throat and mouth pressing on the glossopharyngeal nerve.

What does glossopharyngeal neuralgia feel like?

Glossopharyngeal neuralgia is characterized by a sharp, jabbing pain deep in the throat, or in the tongue, ear, and tonsils, lasting a few seconds to a few minutes. Glossopharyngeal neuralgia is generally caused by a small blood vessel that presses on the nerves as they exit the brainstem.

How long does GPN last?

Typical GPN is characterized by recurring paroxysmal attacks of severe unilateral pain in the area of the glossopharyngeal nerve distribution. The pain is often described as electric shock-like, shooting, or stabbing, and lasts for a few seconds to 2 minutes.

How glossopharyngeal nerve is tested?

The glossopharyngeal nerve provides sensory supply to the palate. It can be tested with the gag reflex by touching the pharynx with a tongue depressor or by touching the arches of the pharynx.

What is glossopharyngeal nerve nucleus?

The nuclei for the glossopharyngeal nerve all lie in the inferior pontine and medullary regions of the brainstem. The nuclei that contribute to it include: (Rostral) Solitary nucleus: special sense of taste. Dorsal motor nucleus: secretomotor to the oropharynx.

Where is glossopharyngeal nucleus located?

Glossopharyngeal nerve is a mixed nerve that consists both of the motor and sensory fibers that rise from its nuclei. This nerve has altogether 4 nuclei that are located in the medulla oblongata: The ambiguous nucleus.
