Bell's Palsy (Ophthalmology)

Acute

What is Bell's Palsy?

Bell's palsy is a condition that causes sudden weakness in the muscles on one side of the face. In most cases, the weakness is temporary and significantly improves over weeks. The weakness makes half of the face appear to droop. Smiles are one-sided, and the eye on the affected side resists closing.

  • Headache.
  • Tearing.
  • Drooling.
  • Loss of feeling in the face.
  • Loss of the sense of taste on the front two-thirds of the tongue.

Disordered movement of the muscles that control facial expressions, such as smiling, squinting, blinking, or closing the eyelid.

Complications may include: Irreversible damage to your facial nerve. Irregular regrowth of nerve fibers. This may result in involuntary contraction of certain muscles when you're trying to move other muscles (synkinesis).

The exact cause is unknown. Bell's palsy may be a reaction to a viral infection resulting in inflammation. It rarely occurs more than once. Bell's palsy is characterised by muscle weakness that causes one half of the face to droop. Bell's palsy usually resolves on its own within six months. Physiotherapy can help prevent muscles from permanently contracting. Supportive steroids and antivirals can also be prescribed in some cases.

Unfortunately, there's nothing you can do to prevent Bell's palsy. It's linked to certain viral infections, but not everyone who has those viral infections develops Bell's palsy. If you have risk factors for the condition, like diabetes, obesity or high blood pressure, managing them well may help reduce your risk.

  • Pregnancy
  • Preeclampsia
  • Obesity
  • Hypertension
  • Diabetes
  • Upper respiratory ailments

How is it diagnosed?

In some cases, antiviral medications may be prescribed in addition to steroids to help increase the chance of recovering facial function. People experiencing pain with Bell's palsy may find relief by taking analgesics such as aspirin, acetaminophen, or ibuprofen.

How is it treated?

Treatment for acute myeloid leukemia is vital. It varies with the patient and stage of the disease. Treatment options include

  • Facial nerve decompression.
  • Subocularis oculi fat (SOOF) lift.
  • Implantable devices (e.g., gold weights) placed into the eyelid.
  • Tarsorrhaphy.
  • Transposition of the temporalis muscle.
  • Facial nerve grafting.
  • Direct brow lift.
