Abstract
Although Bell's palsy is the major cause of acute peripheral facial palsy, its pathogenesis remains unknown. Reactivation of the varicella zoster virus has been implicated as one of the main causes of Bell's palsy, however, studies which investigate the varicella zoster virus reactivation in Bell's palsy patients are mostly Japanese and, therefore, personal and geographic characteristics are quite different from our population.
Highlights
Peripheral Facial Palsy (PFP) was described by Sir Charles Bell (1774-1842) in 1821
Varicella zoster virus was detected in two patients (1.7%)
Varicella zoster virus was detected in 1.7% of saliva samples from patients with Bell’s palsy, using polymerase chain reaction (PCR)
Summary
Peripheral Facial Palsy (PFP) was described by Sir Charles Bell (1774-1842) in 1821. Initially, all cases of facial nerve paralysis were called Bell’s palsy (BP). Conclusions: Varicella zoster virus was detected in 1.7% of saliva samples from patients with Bell’s palsy, using PCR. The Varicella Zoster Virus (VZV) was one of the first viruses to be associated with the PFP.
