Introduction:

Bell's palsy is a disorder of rapid onset that is associated with a temporary, and most often, unilateral facial paralysis occurring when cranial nerve VII (facial nerve) becomes swollen, inflamed, or compressed from edema as a result of a viral infection (e.g., herpes simplex virus, varicella-zoster virus, Eptein-Barr virus; Warner & Varacallo, 2018). Onset typically occurs over the course of several hours. Bell’s palsy is notable in that there is no trauma noted to the facial nerve (Dulak & Naqvi, 2018).
