What is the initial treatment for Bell's palsy?

In cases of Bell's palsy, the initial treatment primarily involves the administration of oral glucocorticoids. This approach is based on the understanding that Bell's palsy is thought to be related to inflammation and swelling of the facial nerve, often linked to viral infections. Glucocorticoids help reduce this inflammation, promote recovery, and may improve outcomes for the patient.

The use of antivirals is considered in severe cases or when there's suspicion of a viral etiology that significantly impacts the facial nerve, but glucocorticoids remain the mainstay treatment in most instances. Early treatment within 72 hours of symptom onset has been shown to enhance recovery rates.

The other options do not offer appropriate initial treatment for Bell's palsy. Immediate surgical intervention is not indicated as most cases resolve without surgical measures. Prescription of antibiotics is unnecessary since Bell's palsy is not caused by a bacterial infection. Physical rehabilitation exercises can be helpful in the recovery phase but are not the initial line of treatment. Understanding these dynamics clarifies why oral glucocorticoids are prioritized for managing Bell's palsy.
