The efficacy and safety of acupuncture for Ramsay Hunt syndrome: A protocol for systematic review.

Background: Ramsay Hunt syndrome (RHS), also known as Hunt syndrome, is caused by varicella-zoster virus infection. The virus often invades the facial nerve geniculate ganglion to cause peripheral facial paralysis, accompanied by severe ear pain, auricular herpes zoster, tinnitus, deafness, vertigo, and other inner ear neurologic symptoms. The acupuncture has a long history as a traditional treatment of traditional Chinese medicine for the treatment of Hunt syndrome, with few adverse events and low cost.
