Facial palsy is a relatively common condition that can affect individuals of all ages. It presents as weakness or paralysis of the facial muscles, resulting in drooping or asymmetrical appearance of the face.

While most cases of facial palsy resolve spontaneously, a significant proportion do not, and those patients go on to experience significant social and physical sequelae of facial disfigurement.¹

This article aims to provide GPs with an overview of the current strategies for the evaluation, diagnosis and treatment of facial palsy.

Facial palsy can have various aetiologies, including viral infections (such as HSV), trauma, tumours, and idiopathic causes (Bell’s palsy). Patients typically present with sudden onset hemifacial weakness, which may progress over hours to days. Additional symptoms may include loss of taste, altered tear production, hyperacusis, and facial, ear or jaw pain.^2,3 A thorough history and physical examination may determine the likely site and cause of the facial palsy.
