Taste test of the facial nerve

The taste test of the facial nerve is a method of judging whether the facial nerve is damaged by whether the taste of the patient is normal. Prepare different test solutions (such as sugar water, salt water, acetic acid solution, etc.), and lick the patient's tongue. The examiner will take the test solution separately with a cotton swab and gently apply it to the patient's tongue to make it taste. After each test side, you need to rinse your mouth and try it on both sides.
