MSRA-1456

A 24-year-old man presents to his GP with right-sided facial weakness. He complains of weakness on the right side of his face, especially when smiling or chewing. He also reports occasional twitching of his right cheek, which started 3 days ago after a flu-like illness. However, he notes that it is already starting to improve.

During examination, the GP observes mild impairment of the facial muscles on the entire right side of the patient’s face, including his forehead. Otoscopy is normal, and examination of the eye is unremarkable. The rest of the cranial nerve exam and upper limb neurological exam is normal.

What is the recommended management for this likely diagnosis?
