Understanding Bell’s Palsy: Causes, Symptoms, and Treatment Options

Picture137

Bell’s palsy occurs because of damage to the facial nerve. It causes a temporary weakness or paralysis of the facial muscles and affects one side of your face.

Bell’s palsy can occur at any age and affect men and women equally.

Most people with Bell’s palsy recover full facial strength and expression within a few months or weeks.

Signs and Symptoms of Bell’s Palsy

Symptoms vary among individuals and can be mild weakness or total paralysis of the affected side.

Common symptoms are:

  • Impaired ability to smile, squint, blink
  • Excessive tearing
  • Loss of facial sensation
  • Headache
  • Drooping eyelid on the affected side
  • Dry eye or dry mouth
  • Drooling
  • Pain around the ear
  • Defective hearing or sense of taste
  • Inability to wrinkle the forehead

The symptoms appear suddenly, and you may notice them when you wake up or try to eat or drink.

Causes of Bell’s Palsy

Bell’s palsy occurs due to swelling and compression of the facial nerve causing facial weakness or paralysis.

The direct cause of this nerve damage is unknown, but the viral infection most likely triggers it in most cases.

Common triggers include,

  • Stress
  • Fever
  • Trauma
  • Tooth Extractions
  • HIV
  • Cold sores (herpes simplex virus)
  • Shingles (herpes zoster virus)
  • Lyme Disease (Bacterial Infection)

Risk factors for Bell’s palsy

Bell’s palsy typically affects men and women equally.

  • Family History
  • Pregnancy
  • Diabetes
  • Lung Infection
  • High Blood Pressure
  • Obesity

Diagnosis of Bell’s Palsy

There is no specific laboratory test to confirm the diagnosis of Bell’s palsy.

Your doctor can confirm the diagnosis based on symptoms and physical examination.

Tests to rule out other causes include,

  • Blood tests – To check for Lyme disease or sarcoidosis
  • Electromyography (EMG) – To measure nerve activity and damage
  • MRI or CT scan – To rule out stroke or other causes of nerve damage

It is essential to rule out the presence of a stroke or tumor for appropriate treatment.

Bell’s Palsy Treatment

Bell’s palsy symptoms improve without treatment in most cases. But the muscles can take several weeks or months to regain the normal strength of the facial muscles.

Your doctor may recommend the following Bell’s palsy medications for the relief of symptoms and faster Bell’s palsy recovery:

Medicines

  • Oral corticosteroids help to reduce nerve swelling and regain facial movement faster
  • Antiviral medications may speed recovery

Surgery

  • Decompression surgery eases pressure on the nerve (rarely performed)
  • Plastic surgery procedures to correct facial asymmetry and eyelid closure

Bell’s palsy Eye Treatment

  • Eyedrops to soothe dry and irritated eyes
  • Eye ointment to lubricate eyes overnight
  • An eye patch to protect from irritants and injuries

Eye care is very important if you cannot close your eyelids fully!
