![]() ![]() In some cases, surgery can help take pressure off the nerve. Then, they will offer treatments such as anticonvulsant medications or local anesthesia. If your facial pain results from glossopharyngeal neuralgia, your medical professional may use MRI scans to assist with making a diagnosis. You may also be referred to a neurologist for further evaluation. ![]() Your doctor will examine you for tumors, systemic conditions, and any history of injuries that could have affected your cranial nerves. They’ll likely ask you to explain your symptoms and perform a clinical exam on your head and neck to locate the source of the problem. If you think you’re experiencing glossopharyngeal nerve damage or issues, contact your doctor or dental professional. Because this nerve includes fibers with motor (movement) and sensory functions, doctors call it a “mixed nerve.” Finally, it helps move the throat during swallowing and talking, according to a review in the Journal of Neurosciences in Rural Practice. It also controls some motor fibers that help produce saliva as part of the parasympathetic nervous system, the system that's active when your body is resting and digesting. To help you visualize where this nerve is interacting with your oral cavity and throat, the University of Texas McGovern Medical School explains that this nerve is responsible for sensory fibers in the soft palate (roof of the mouth), the upper pharynx (throat), the tonsils, and the back portion of the tongue. The glossopharyngeal nerve relays sensory information from many structures of the head and neck, provides taste sensations from the back of the tongue, helps with muscle contraction during swallowing, and stimulates saliva flow from the parotid glands. The glossopharyngeal nerve stems out of the medulla oblongata, which is at the base of your brain and ends in the pharynx near the base of the tongue. ![]()
