Bell's Palsy Or Facial Palsy Treatment Doctors in Delhi

Bell's palsy (also known as idiopathic facial paralysis) is a condition affecting the facial nerve causing paralysis of the facial muscles on one or both sides of the face. Its onset is usually rapid leading to facial drooping, inability to control the facial muscles and difficulty closing the eyelids. It is thought that the nerve controlling the muscles of face (VII cranial nerve) becomes inflamed in its bony canal which affects the transmission of nerve impulses. Facial weakness can occur in other conditions such as stroke, brain tumours or head trauma. It is only when other causes are excluded that the facial weakness is attributed to Bell's palsy.

The condition in many cases resolves quickly, especially for those with partial paralysis. Drug treatment such as antiviral treatment or steroid treatment may be offered for some patients. Physiotherapy treatment may be indicated to help speed recovery with facial exercises or electrical stimulation.

The symptoms of Bell’s palsy can appear one to two weeks after a person has had cold, ear infection, or eye infection. They usually appear abruptly, and the patient may notice them when he/ she wakes up in the morning or tries to eat or drink. Bell’s palsy is marked by a droopy appearance on one side of the face and the inability to open or close the eye on the affected side. In rare cases, Bell’s palsy may affect both sides of the face.

Other signs and symptoms of Bell’s palsy include:

· Drooling

· Twitching

· Facial tingling

· Moderate or severe headache/neck pain

· Memory problems

· Balance problems

· Ipsilateral limb paresthesias

· Ipsilateral limb weakness

· Significant facial distortion.

· Drooping eyelid or corner of the mouth

· Drooling

· Dry eye or mouth

· Impairment of taste

· Excessive tearing in the eye (crocodile tears).

· A sense of clumsiness

Contact your doctor immediately if you develop any of these symptoms. The patient should never self-diagnose Bell’s palsy. The symptoms can be similar to those of other serious conditions, such as a stroke or brain tumour.

Although the exact immediate reason Bell's palsy or facial paralysis occurs isn't clear, it’s more often noticed to be related to having a viral infection. Viruses that have been linked to Bell's palsy include viruses that cause:

· Cold sores and genital herpes (herpes simplex)

· Chickenpox and shingles (herpes zoster)

· Infectious mononucleosis (Epstein-Barr)

· Cytomegalovirus infections

· Respiratory illnesses (adenovirus)

· German measles (rubella)

· Mumps (mumps virus)

· Flu (influenza B)

· Hand-foot-and-mouth disease (coxsackievirus)

The nerve that controls your facial muscles passes through a narrow corridor of bone on its way to your face. In Bell's palsy, that nerve becomes inflamed and swollen — usually related to a viral infection. Besides facial muscles, the nerve affects tears, saliva, taste and a small bone in the middle of your ear.

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 tumours — can cause facial muscle weakness that mimics Bell's palsy. If the cause of your symptoms isn't clear, your doctor may recommend other tests, including:

· Electromyography (EMG). This test can confirm the presence of nerve damage and determine its severity. An EMG measures the electrical activity of a muscle in response to stimulation and the nature and speed of the conduction of electrical impulses along a nerve.

· Imaging scans. Magnetic resonance imaging (MRI) or computerized tomography (CT) may be needed on occasion to rule out other possible sources of pressure on the facial nerve, such as a tumour or skull fracture.

Most people with Bell's palsy recover fully — with or without treatment. There's no one-size-fits-all treatment for Bell's palsy, but your doctor may suggest medications or physical therapy to help speed your recovery. Surgery is rarely an option for Bell's palsy.

Commonly used medications to treat Bell's palsy include:

· Corticosteroids, such as prednisone, are powerful anti-inflammatory agents. If they can reduce the swelling of the facial nerve, it will fit more comfortably within the bony corridor that surrounds it. Corticosteroids may work best if they're started within several days of when your symptoms started.

· Antiviral drugs. The role of antivirals remains unsettled. Antivirals alone have shown no benefit compared with placebo. Antivirals added to steroids are possibly beneficial for some people with Bell's palsy, but this is still unproved.

However, despite this, valacyclovir (Valtrex) or acyclovir (Zovirax) is sometimes given in combination with prednisone in people with severe facial palsy.

Paralyzed muscles can shrink and shorten, causing permanent contractures. A physical therapist can teach you how to massage and exercise your facial muscles to help prevent this from occurring.

In the past, decompression surgery was used to relieve the pressure on the facial nerve by opening the bony passage that the nerve passes through. Today, decompression surgery isn't recommended. Facial nerve injury and permanent hearing loss are possible risks associated with this surgery.

Rarely, plastic surgery may be needed to correct lasting facial nerve problems. Facial reanimation helps to make the face look more even and may restore facial movement. Examples of this type of surgery include eyebrow lift, eyelid lift, facial implants and nerve grafts. Some procedures, such as an eyebrow lift, may need to be repeated after several years.
