G52.1: Disorders of glossopharyngeal nerve [9th cranial nerve]

Your glossopharyngeal nerve is damaged.

The glossopharyngeal nerve runs from the brain to the back of the tongue, to the throat and towards the ear. Among other things, the glossopharyngeal nerve is important for some of the movements we make when speaking and swallowing. The glossopharyngeal nerve can also be used to perceive taste at the back of the tongue. This nerve also affects how much saliva is formed.

Damage to the glossopharyngeal nerve can produce a range of different symptoms. For example, your voice may sound hoarse. You may have problems when swallowing. You may also no longer be able to taste as well as you used to.
