Can Bells Palsy come and go?
Can Bells Palsy come and go?
For most people, Bell’s palsy is temporary. Symptoms usually start to improve within a few weeks, with complete recovery in about six months. A small number of people continue to have some Bell’s palsy symptoms for life. Rarely, Bell’s palsy can recur.
Can a doctor tell if you have Bell’s palsy?
There’s no specific test for Bell’s palsy. Your doctor will look at your face and ask you to move your facial muscles by closing your eyes, lifting your brow, showing your teeth and frowning, among other movements. Other conditions — such as a stroke, infections, Lyme disease and tumors — can cause facial muscle weakness that mimics Bell’s palsy.
What kind of facial paralysis does Bell’s palsy cause?
Supranuclear (central) lesions affecting the facial nerve will not paralyze the forehead on the affected side, resulting in a unilateral facial paralysis with forehead sparing. Often, there will be at least some weakness of extremities on the affected side as well.
How long does it take for Bell’s palsy to develop?
Article Sections. Bell’s palsy is a peripheral palsy of the facial nerve that results in muscle weakness on one side of the face. Affected patients develop unilateral facial paralysis over one to three days with forehead involvement and no other neurologic abnormalities.
How are corticosteroids used for Bell’s palsy?
Your doctor may also give you a short course of corticosteroids (like prednisone ). The goal is to decrease swelling of your facial nerve. This may shorten the duration of your Bell’s palsy symptoms. In the meantime, your doctor will tell you to take extra care to protect your eye on the affected side.
How is a diagnosis of Bell’s palsy made?
A diagnosis of Bell’s palsy is made based on clinical presentation — including a distorted facial appearance and the inability to move muscles on the affected side of the face — and by ruling out other possible causes of facial paralysis. There is no specific laboratory test to confirm diagnosis of the disorder.
How is the facial nerve affected by Bell’s palsy?
Anatomy of the facial nerve. Patients with Bell’s palsy typically complain of weakness or complete paralysis of all the muscles on one side of the face. The facial creases and nasolabial fold disappear, the forehead unfurrows, and the corner of the mouth droops.
Can a person with Bell’s palsy regain muscle function?
In those rare cases when Bell’s palsy has caused permanent paralysis of one side of the face, the peripheral facial nerve can be surgically connected with the spinal accessory or hypoglossal nerves to allow some eventual return of muscle function.
Can a person with Bell’s palsy close their eyes?
Patients with Bell’s palsy may be unable to close the eye on the affected side, which can lead to irritation and corneal ulceration. The eye should be lubricated with artificial tears until the facial paralysis resolves. Permanent eyelid weakness may require tarsorrhaphy or implantation of gold weights in the upper lid.
