Two cases of pharyngolaryngeal zoster advanced to multiple cranial neuropathy.

Varicella zoster virus (VZV) infection of the head and neck region may present with various symptoms. I present two cases of VZV infection of the pharynx and larynx with multiple cranial nerve neuropathies. Their initial symptoms such as sore throat, odynophagia, and dysphasia were complicated by otalgia, dizziness, hearing loss, or ipsilateral facial nerve paralysis. All of these lesions tended to lateralize to the ipsilateral side and endoscopic findings suggested VZV infections, which were confirmed by serial serologic examinations.
