Herpes viruses may contribute to the development of Bell’s palsy, although the mechanism is complex and definitive causal association is questioned. In HSV workup, PCR testing using cerebrospinal fluid (CSF) is a rapid, minimally invasive diagnostic technique. In some patients with Bell’s palsy, HSV-1 can be detected in the CSF. It is also used to detect HSV-2 as the cause of recurrent meningitis (Mollaret) and asymptomatic viral shedding.
