Prevalence of taste disorders in idiopathic and B. burgdorferi-associated facial palsy.

The frequency of taste disorders in idiopathic facial palsy (IFP) and B. burgdorferi-associated facial palsy (BFP) was retrospectively assessed in a cohort of patients with acute peripheral facial palsy (AFP). A significant (>10/microl) CSF pleocytosis was found in 17% of the patients who underwent lumbar puncture for AFP.
