Question

Quizplus · Accepted Answer

Bell's palsy is a disorder of the facial nerve (seventh cranial nerve) that causes a sudden onset of weakness or paralysis of facial muscles. The severity of paralysis in Bell's palsy varies widely. The patient may be aware of pain or a drawing sensation behind the ear, followed by an inability to open or close the eye and drooping of the mouth and drooling of saliva. Often the disorder is first noticed in the morning, having developed overnight. Initially, the patient is unable to smile, whistle, or grimace, and the facial expression is distorted (see Figure 13-21). Taste perception may be diminished, contributing to loss of appetite. The condition is usually unilateral. It may be transient or permanent and usually occurs between 20 and 60 years of age, in men and women alike. The individual reporting sudden onset of one-sided facial paralysis requires prompt assessment to rule out a CVA. Referral is usually to an emergency facility for diagnosis.
