Borreliosis as a cause of peripheral facial palsy: a multi-center study.

Borreliosis is known to be a common cause of peripheral facial palsy in Stockholm and its vicinity. The aim of the present study was to investigate the frequency and characteristics of borreliosis among patients with peripheral facial palsy in different parts of Sweden. All serological tests were performed in one laboratory.

Central nervous system involvement in patients with facial palsy due to borrelial infection.

Patients with a peripheral facial palsy due to an underlying Ixodes-borne borreliosis often have cerebrospinal fluid findings indicating meningeal involvement. The aim of the present study was to identify signs of CNS involvement by means of brain-stem evoked response audiometry (BSER) in patients with a facial palsy due to borreliosis, as well as in patients with a facial palsy of unknown aetiology. Bell's palsy.

Tick-borne borreliosis and facial palsy.

During a one-year period, 82 consecutive patients seeking medical attention for facial palsy primarily of unknown etiology were examined for underlying Ixodes ricinus-borne borreliosis. Evidence of the infection was found in 16 (20%) of the patients, most of whom had cerebrospinal fluid findings indicating meningeal involvement. Among 9 children included in the study, borreliosis was found in 6 cases.
