Resumo

To the Editor: A 72-year-old white male presented with headaches. He developed pain in his left ear and consulted an otolaryngologist who considered an otitis infection or herpes zoster. He was treated with corticosporin otic suspension and benzocaine/antipyrine otic drops with minimal improvement. He subsequently developed small vesicles in the concha of the auricle of his left ear, hearing loss, and tinnitus. An audiogram revealed bilateral high frequency hearing loss with the left side more affected than the right. Magnetic resonance imaging revealed no signs of tumor or infection. He was treated with methylprednisolone and acyclovir. Three months later, he continued to complain of pain in his left ear and the onset of slurred speech. Physical examination revealed deviation of the tongue to the left with left hemiatrophy of the tongue (Fig 1). A neurological consult confirmed chronic tinnitus and hearing loss of the left ear, left tongue atrophy, deviation of the tongue to the ipsilateral side, and mild left facial paresis. Serology results for herpes simplex virus 1 and 2 were positive for IgG antibodies and negative for IgM antibodies. Varicella-zoster virus (VZV) IgG antibodies were positive, but IgM antibodies were negative. A repeat magnetic resonance imaging scan failed to show an infarct, tumor, or infection. He was started on famciclovir and prednisone with minimal improvement.Herpes zoster oticus (Ramsay Hunt syndrome) was described by James Ramsay Hunt in 1907.1Hunt J.R. On herpetic inflammations of the geniculate ganglion: a new syndrome and its complications.J Nerv Ment Dis. 1907; 34: 73-96Crossref Scopus (302) Google Scholar He concluded that the syndrome resulted from a reactivation of VZV in the geniculate ganglion, which was later confirmed by polymerase chain reaction studies demonstrating the presence of VZV DNA in the geniculate ganglion.2Van de Steene V.

Subsequently, he described involvement of CN VIII (the vestibulocochlear nerve) with hearing loss, tinnitus, vertigo, and nystagmus.The brainstem contains the nuclei for CNs III through XII, which are in close anatomical proximity. Ramsay Hunt syndrome is a common expression of two CN nuclei (VII and VIII) which are adjacent to each other. Other examples of Ramsay Hunt syndrome associated with adjacent CN nuclei include reports involving CNs V, VI, IX, and X.3Shah R.K. Blevins N.H.
