A 12-year-old girl presented with the onset of unilateral facial weakness. She had developed some mild tingling over her left cheek and reported that blinking with her left eye felt unusual. She dribbled a small amount of fluid when she drank and her mother had noticed a asymmetry of her face. There was no local pain or any other symptom. The girl was healthy and did not take any medication. There had been no recent head injury, dental intervention or other trauma.

She did not have fever, cough, aches or pains suggestive of infection. She did not have a tick bite or ear discharge. What can be the most probable diagnosis for this facial weakness? *This image based case is from Docplexus editorial team for educative purpose only. Source: Haymarket group
