Cranial Polyneuropathy in Ramsay Hunt Syndrome Manifesting Severe Pharyngeal Dysphagia: a Case Report and Literature Review

ABSTRACT

Ramsay Hunt syndrome (RHS) is characterized by herpes zoster oticus, facial nerve palsy, and vestibulocochlear symptoms. Dysphagia caused by the involvement of multiple cranial nerves (CNs) in RHS is very rare. We encountered a rare case presented with severe dysphagia due to cranial polyneuropathy involving trigeminal nerve (CN V), facial nerve (CN VII), vestibulocochlear nerve (CN VIII), glossopharyngeal nerve (CN IX), vagus nerve (CN X), and hypoglossal nerve (CN XII) in RHS. This case report suggested that the prognosis for dysphagia in RHS seems favorable, and swallowing rehabilitation therapy could be beneficial in expediting tube removal.
