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
This neuralgia is usually idiopathic; however, it may also be a result of a structural lesion along the course of the glossopharyngeal nerve such as tumor, infection, or neuroma. Unlike trigeminal neuralgia, MS is a very rare cause of this syndrome.44 Symptoms may respond to carbamazepine,45 oxcarbazepine,46 phenytoin, gabapentin, or baclofen. In refractory cases, surgical options such as microvascular decompression,47 nerve resection, tractotomy, or Gamma Knife radiosurgery48 may relieve symptoms.

The glossopharyngeal nerve is sensory from the posterior third of the tongue and the mucous membrane of the pharynx. It contains taste fibres from the posterior third of the tongue. The glossopharyngeal nerve is very rarely damaged alone. The vagus is motor for the soft palate, pharynx and larynx. It is also sensory and motor for the respiratory passages, the heart and – through the parasympathetic ganglia – most of the abdominal viscera. Damage to the vagus is clinically obvious through its palatine and laryngeal branches.
Ultrasound-guided repetitive pulsed peripheral magnetic stimulation provides pain relief in refractory glossopharyngeal neuralgia: A case report

The case reported here adds to our current understanding of potential applications of rPMS. First, the patient was refractory to conservative, pharmacologic, and advanced pain management therapies (e.g., glossopharyngeal steroid nerve block and pulsed radiofrequency neuromodulation). Targeted rPMS delivered to the glossopharyngeal nerve using ultrasound guidance provided immense and immediate pain relief exceeding the analgesic effect of any previous therapy. After a number of sessions, the patient experienced no pain for several hours, which she had not experienced since the start of her symptoms. Second, our case is the first report of rPMS using image guidance to direct the magnetic beams. Ultrasound has revolutionized pain medicine in its ability to provide real-time accuracy in identifying anatomical structures for interventional procedures (e.g., directing needle placement for nerve blocks, joint injections). Improved accuracy afforded by image guidance has led to superior outcomes such as increased efficacy rates and fewer side effects with pain injection therapy. Similarly, image guidance could allow improved benefit by nerve localization with rPMS.
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].

Horner’s syndrome, carotid body syndrome, and sensorineural symptoms such as hearing loss and tinnitus are far less common but have been reported. In 2010, Gama and Cabral reported a case of a 46-year-old woman who presented with sudden and repeated episodes of syncope.21 The CBT was stretching the baroreceptors of the carotid sinus, which is located in the wall of the internal carotid artery 38 mm above the bifurcation. This, in turn, resulted in paroxysmal overstimulation of the parasympathetic system. And the ensuing bradycardia led to the syncopal episodes. Athanasios et al.12 reported a case of a 57-year-old man with a painless left-sided neck mass that had been present for several years. His presenting symptoms included dysphagia, alteration of taste, and pain on palpation of the left auricle.12 This patient’s clinical manifestation was due to a CBT’s direct impingement on the lingual branch of the glossopharyngeal nerve and the auricular branch of the vagus nerve, which innervates the posterior third of the tongue and supplies sensory fibers to the skin of external acoustic meatus, respectively. In both cases, surgical removal of the tumors successfully restored the functional deficits. The patients remained asymptomatic at the 2-year follow-up.
