Cranial Neuropathies I, V, and VII–XII
Published in Philip B. Gorelick, Fernando D. Testai, Graeme J. Hankey, Joanna M. Wardlaw, Hankey's Clinical Neurology, 2020
Glossopharyngeal neuralgia is a rare condition characterized by recurrent brief episodes of unilateral sharp lancinating pain in the throat, ear, base of tongue, or neck, usually in response to chewing, coughing, yawning, or swallowing due to a ‘trigger point’ in the throat. The pain is stereotyped lasting seconds to minutes. Occasionally, bradycardia and syncope occur (associated with swallowing or coughing), possibly due to cross-stimulation of the carotid sinus via the carotid nerve.
Abnormal Skull
Published in Swati Goyal, Neuroradiology, 2020
It is a sensory nerve specialized for taste sensation in the posterior third of the tongue. It also receives sensory fibers from the middle ear, pharynx, and viscerosensory fibers from the carotid body and sinus. It supplies motor fibers to the stylopharyngeus muscle and parasympathetic fibers to the parotid gland via the otic ganglion. Irritation of the nerve may result in glossopharyngeal neuralgia.

Jugular foramen tumours that extend medially and anteriorly can present with loss of bulbar function, hoarseness, dysphagia, dysarthria or shoulder weakness. They often cause these deficits long before the development of auditory or vestibular symptoms. Any isolated or combination of lower cranial nerve palsies should be investigated by imaging the skull base. The sequence of images must be extended to include the full length of the relevant nerve(s). Neuralgias of the lower cranial nerve include the uncommon glossopharyngeal neuralgia and the even more rare laryngeal nerve neuralgia. Glossopharyngeal neuralgia is characterized by attacks of excruciating unilateral pain of short duration of the ear, throat or neck. Pain can be triggered by swallowing, chewing, coughing, yawning or head movements and in about 10% of patients it is also associated with syncope due to reflex bradycardia.43 There are seven reported cases of schwannoma of tympanic branch of glossopharyngeal nerve (Jacobson’s nerve).44
Comparison between landmark and ultrasound-guided percutaneous peristyloid glossopharyngeal nerve block for post-tonsillectomy pain relief in children: a randomized controlled clinical trial

Several studies have described glossopharyngeal nerve block in pain therapy or post-operative analgesia using different techniques; however, the current trial is novel in comparing the landmark techniques against ultrasound techniques in pediatric age group undergoing tonsillectomy with a primary outcome of time to first analgesic requirement and secondary outcomes giving a spotlight on easiness and anesthetist satisfaction. Earlier trials of glossopharyngeal nerve block used the intraoral technique [8], and some performed the para-pharyngeal not the peristyloid technique in cadaver and volunteer sonoanatomy study [9]. Some studies compared the extraoral and intraoral routes of glossopharyngeal nerve block for pain relief in patients with carcinoma of the tongue, and some trials used extra oral glossopharyngeal nerve block in glossopharyngeal neuralgia [9–11].
Ultrasound-guided repetitive pulsed peripheral magnetic stimulation provides pain relief in refractory glossopharyngeal neuralgia: A case report
Published in Canadian Journal of Pain, 2023

A 70-year-old female with an 8-year history of glossopharyngeal neuralgia resulting from a lingual tumor resection was sent to our clinic for consultation. She had seen several pain physicians at a tertiary academic care center and failed pharmacologic (i.e., neuropathic pain medications, opioids, cannabinoid products) and interventional techniques (nerve blocks, pulsed radiofrequency neuromodulation). Daily mean pain score, collected over the preceding 3 days, was reported to be a 4.2 (SD 2.5) on a 0 to 10 numeric rating scale (NRS). Each day, her pain was low in the morning (mean 1.2, SD 0.8), moderate at midday (average score 5.2, SD 1.8), and severe in the evening (mean 7, SD 1.0).
