Arnason S, et al. - Among children (aged 0 to 18 years) in the Borrelia high-endemic region of Stockholm who visited a Paediatric Emergency Department during a 1-year period from 2014 to 2015, researchers identified the incidence, aetiology, and prognosis of acute peripheral facial nerve palsy (FNP). In order to measure the clinical outcomes, the Sunnybrook and House-Brackmann facial grading systems were used. In total, 77 children were identified with FNP, an estimated incidence of 30 per 100,000 children/year. During the study period, neuroborreliosis and IFP were the major causes of FNP. In younger ages, facial palsy associated with neuroborreliosis had a seasonal variation and dominated.
