Unilateral facial swelling caused by Ramsay Hunt syndrome resembles odontogenic infection.

Facial cellulitis and swellings of the head and neck are worrisome signs of odontogenic infection, which can be life threatening. Most head and neck infections are caused by bacterial pathogens. When treating such infections, dentists must also be aware of possible viral or fungal causes and their associated presentations. This report documents a case of viral infection that initially resembled a bacterial odontogenic infection. It is intended to familiarize dentists with the Ramsay Hunt syndrome and the need for prompt recognition and early definitive treatment.
