A case of Ramsay Hunt syndrome treated by facial nerve decompression via transmastoid/supralabyrinthine approach

Ramsay Hunt syndrome (RHS) is a disease that shows a triad of facial palsy, vesicles on auricle, and hearing symptoms. This syndrome is characteristic of herpetic inflammation activation on the geniculate ganglion due to reactivation of varicella-zoster virus. Based on the pathogenesis of disease, high dose corticosteroids with antiviral agents are recommended as first line treatment. However, for those who are anticipated with unfavorable prognosis, surgical decompression of facial nerve is considered as an appropriate option. Currently, surgical treatment is recommended to be performed within 14 days, and electrophysiologic tests such as electroneurography, electromyography are used for selection of adequate subjects. A 56 year-old male diagnosed of RHS was treated with Facial nerve decompression via transmastoid/supra-labyrinthe approach and showed favorable prognosis. We reviewed this case with relevant publishings in medical literature.
