What is a glossopharyngeal nerve?

Glosopharyngeal nerve is also called the ninth skull nerve. Cranial nerves are vital nerves that come from the brain that help control brain muscles, process five senses and control the glands in the body. As the name suggests, the glossopharyngeal nerve comes from the brain near the skull base, leaving the skull through a large hole called jugular foramen and ending in the back of the mouth and neck. Glosopharyngeal nerve allows you to perceive the taste of the most confident part of the tongue, bringing feelings of pain and touch from the throat and tongue, and checking over the muscles used in swallowing. Isolated lesions of the ninth nerve are very rare. Tumors at the intersection between the mose and the monos in the brain stem can damage the eighth nervous, which mediates balance and hearing, as well as the ninth nerve. Masses near the jugular foramen can compress the ninth, tenth and eleventh nerves. Difteria can cause the ninth paralysis of the nerves. The matches of unconsciousness associated with swallowing, called swallow syncope, are rare complicationsme the ninth and tenth nerve lesions.

abnormalities of glossopharyngeal nerve cause swallowing problems. Disabled patients notice the disturbed taste of the back of one third of the tongue and palate. On the back of the tongue, palate and neck can be a reduced feeling of touch or pain. In these cases there is no gag reflex. The dysfunction of the mop -grafted gland leads to a reduction in the production of saliva and dry mouth.

With matches from seconds to minutes, glossopharyngeal neuralgia is a condition in which in the ear, neck, almonds and tongues there are recurrent attacks of unbearable pain. The cause of neuralgia is irritation of glossopharyngeal nerve due to pressure from nearby blood vessels, tumors, growth or infections in the skull, mouth or neck. The triggering activities for pain attacks include swallowing, speaking, laughter, cough or chewing. After a slow rhythm and fainting, they occurred with severely painful episodes. If the surgical lE -adequate is not obvious, anti -tours such as gabapentin, phenytoin and carbamazepine, and some antidepressants, such as amitriptylin, are effective in managing symptoms.

In neurosurgical operations near the skull, there is a risk of cranial nerve injuries, including glossopharyngeal nerve, which can be avoided during the case. Electric stimulation of nerve strains and electromyographic records facilitates the identification of skull nerves before starting operation. These techniques also monitor the skull nerves during surgical removal of the tumor is located at the base of the skull. As the tumor removal proceeds, the surgeon can ensure that surgical trauma does not observe changes in the size, shape and outline of responses.
