Background: This type of pain syndrome occurs suddenly and briefly, beginning unilaterally from one side of the face. Modestly stimulating speech can provoke it, affecting the ear, tongue, throat, and jaw angle. Interestingly, it is the sensory distribution of the auricular and the pharyngeal branches of the cranial nerves IX and X. People have not had a confirmed case of glossopharyngeal neuralgia (GPN), along with oromandibular dystonia (OMD). Nevertheless, usually in the medical literature, this case report supplies information about a patient who has concurrent GPN and OMD.
Case description: A 36-year-old male patient presented with a history of sudden onset of increasing electric pains, which were centered in the middle of the forehead to the depth of the throat and accompanied by uncontrolled movements, repetitive tongue protrusions, jaw movements, and recurrent pervasive gagging reflexes. Magnetic resonance imaging showed that a vascular loop of the superior cerebellar and anterior inferior cerebellar artery on the left side had crossed over and compressed those nerves. Decompression surgery in the left glossopharyngeal and trigeminal nerves cured all the symptoms.
Conclusion: The simultaneous occurrence of GPN and OMD is rare, complex, and challenging from the clinician's viewpoint in the management of similar but different pathologies. A detailed history was taken, and a radiological investigation was called to devise a management plan in the context of understanding the pathology of both disorders.
