[Central or peripheral facial palsy ?].

A 34-year-old patient presents to the emergency department with new-onset left-sided facial asymmetry and difficulty chewing on the left side. Clinical examination revealed no lesion in the left ear canal but a left facial paralysis with labial ptosis and the sign of Cils of Souques, a difficulty in closing the left eye, leading to the diagnosis of left peripheral facial nerve damage. No other neurological sign was present. The evolution was favorable after treatment with glucocorticoids, physiotherapy and eye protection.
