If you experience severe pain in the eye of the ear, be alert to the possibility of linguopharyngeal neuralgia. Glossopharyngeal neuralgia is a recurrent paroxysmal severe pain that occurs in the linguopharynx and deep in the ear. The clinical manifestations of this disease were first reported by Weisenburg in 1910, and in 1921 Harris proposed that linguopharyngeal neuralgia is an independent cranial neuralgia. The incidence is about 2% of that of trigeminal neuralgia. The disease usually occurs after 40 years of age, and there is no significant difference in the incidence between men and women. Left-sided pain is more common than right-sided, and bilateral pain is present in about 2% of cases. The pathogenesis of this type of pain is similar to that of primary trigeminal neuralgia, which is due to the compression of blood vessels, resulting in demyelination of the linguopharyngeal and vagus nerve filaments, causing a “short circuit” between the nerve fibers and triggering the pain attack. Secondary linguopharyngeal neuralgia: It can be secondary to various tumors around the linguopharyngeal nerve, vertebral arteriosclerosis, aneurysm, residual inferior lingual artery, arachnoiditis, local infection, excessive stem length, ossification of the ligament of the stem ligament, injury to the extracranial segment of the linguopharyngeal nerve, occlusion of the extracranial end of the internal carotid artery and stenosis of the external carotid artery, resulting in ischemic changes in the linguopharyngeal nerve near the jugular foramen and formation of pseudo-synapses. The main drug treatment is carbamazepine, but microvascular decompression of the linguopharyngeal nerve is required for radical treatment.
