Abstract

Influenza virus has been reported to have various neurologic involvements, and it is known to be a potential cause of facial palsy. However, no single case of facial palsy caused by H1N1 has been reported as far as we know. Here we report a 13-year-old girl infected with influenza A H1N1 whose clinical course was complicated by bilateral facial nerve palsy. The patient presented with bilateral facial muscle weakness, and showed decreased amplitude of CMAP from both nasalis on the eighth day after onset. Oral prednisolone was prescribed and she showed clinical improvement. Follow-up facial electroneuronography on the twenty eighth day showed improvement of CMAP amplitude, and the patient showed complete recovery three months after onset.

Key Words: Influenza A H1N1, Bilateral facial nerve palsy
