Bell's palsy

 [belz]
neuropathy of the facial nerve, resulting in paralysis of the muscles on one side of the face. The person usually has sagging on one side of the mouth, with drooling and lack of ability to whistle. Care must be taken when eating to avoid inadvertent trauma. If the eye on the affected side cannot be closed, it may become tearful and inflamed.
Bell's palsy. From McQuillan et al., 2002.


Bell's palsy is often no more than a temporary condition lasting a few days or weeks. Occasionally it may be the result of a tumor pressing on the nerve or physical trauma to the nerve. In this event, recovery will depend on the success in treating the tumor or injury. More often, however, the cause is unknown. In many cases the deformity can be reduced by plastic surgery.

Bell's palsy

n.
A unilateral facial muscle paralysis of sudden onset, resulting from trauma, compression, or infection of the facial nerve and characterized by muscle weakness and a distorted facial expression.

Bell's palsy

Etymology: Charles Bell, Scottish Surgeon, 1774-1842
a unilateral paralysis of the facial nerve, thought to result from trauma to the nerve, compression of the nerve, or infection, of which herpes simplex virus is thought to be the most common. Any or all branches of the nerve may be affected. The person may not be able to close an eye or control salivation on the affected side. It usually resolves over weeks but can leave some permanent damage, including decreased taste and hypersensitivity to noise on the affected side. Also called Bell's paralysis.

Bell's palsy

Bell's paralysis, facial nerve palsy Neurology A condition affecting the 7th–facial nerve, resulting in unilateral facial paralysis; BP can be differentiated from a central–stroke deficit by inability to raise eyebrow on affected side. See Facial nerve.

Bell's palsy

Paralysis of some or all of the muscles on one side of the face, so that the corner of the mouth droops, the lower lid falls away, and the affected side of the face becomes flattened and expressionless. Many cases of Bell's palsy are due to herpes simplex virus infections. Polymerase chain reaction amplification has shown the herpes simplex virus genome in a high proportion of cases. A faster and more complete recovery can often be achieved by treatment with the anti-herpes drug aciclovir (Zovirax). The early use of steroids such as prednisolone also improves the prognosis. (Sir Charles Bell, 1774–1842, Scottish surgeon).

Bell's palsy

Facial paralysis or weakness with a sudden onset, caused by swelling or inflammation of the seventh cranial nerve, which controls the facial muscles. Disseminated Lyme disease sometimes causes Bell's palsy.

Q. What are the causes of bell's palsy?

A. I had it 5 years ago at age 20. All the symptoms of the above are correct not to mention the tiredness and rapid blinking of the eye from the effected side.

In my case I have just found out that I have a non milignate tumor behind my left eye which was likely to be the cause of the Bell Pausy in the first place. I encourage anyone who has symptoms or pain spanning more than 8 weeks to see their doctor and if possible request request or demand a MRI scan for peace of mind.

If pain persists get a second opinion and dont let the Dr. shrugg you off.
