Involvement of the facial nerve and geniculate ganglion produces what syndrome, characterized by facial paralysis and otalgia (earache)?

Answer :

Final answer:

Ramsay Hunt syndrome is characterized by facial paralysis and otalgia due to the involvement of the facial nerve and geniculate ganglion after herpes zoster. It is a type of postherpetic neuralgia which persists after the shingles lesions have resolved, and the varicella-zoster virus reactivation affects the geniculate ganglion.

Explanation:

The syndrome caused by involvement of the facial nerve and geniculate ganglion following an attack of herpes zoster, resulting in facial paralysis and otalgia, is known as Ramsay Hunt syndrome. This condition is an example of a postherpetic neuralgia, which is a complication from the reactivation of the varicella-zoster virus, the same virus that causes chickenpox and shingles. Individuals with this syndrome frequently experience severe pain, and treatment typically involves antiviral medications and pain management strategies.

Postherpetic neuralgia is the persistent pain that can last weeks to many months after the initial herpes zoster rash has healed. The varicella-zoster virus can become dormant in nerve cells and may be reactivated by stress, aging, immunosuppression, or other factors. In the case of Ramsay Hunt syndrome, the virus affects the geniculate ganglion leading to the characteristic symptoms of facial paralysis and earache.
