Otology A8


Bell’s palsy

Bell’s palsy accounts for 60-70% of unilateral facial paralysis, occurring equally in both sexes with a peak at 40-years-old. The exact aetiology is unknown though there may be a role of HSV. It typically presents as an acute unilateral lower motor neurone facial palsy, which may be preceded by periauricular paraesthesia or otalgia. Hyperacusis, dry eyes, and a viral prodrome may also occur but hearing loss should not be present. Prednisolone 1 mg/kg up to a maximum of 60 mg per day for 7-10 days is indicated in Bell’s palsy if presenting within 72 hours of the initial onset.
