Acute facial nerve palsy in children in a Lyme disease-endemic area in the Netherlands

We assessed the prevalence of Lyme neuroborreliosis in children with acute facial nerve palsy in a Lyme-endemic region and patient characteristics associated with this. All children visiting one of three participating hospitals between January 2010 and December 2016 were included in the study. Of 104 children referred to the hospital with facial nerve palsy, 43% had Lyme neuroborreliosis and 57% idiopathic facial palsy. Characteristics significantly associated with Lyme neuroborreliosis were headache (55% versus 18%), meningeal irritation (21% versus 5%), presentation in summer months (69% versus 37%), and a previous tick bite (33% versus 7%).
