Overview of Bell’s Palsy

Bell’s palsy is a sudden temporary weakness or paralysis of the facial muscles and usually affecting one side of the face. It occurs due to inflammation or compression of the facial nerve, which controls muscle movements in the face muscles. This condition can cause a drooping face, difficulty in closing one eye, and an uneven smile. Although it may resemble a stroke. Bell’s palsy is not life threatening and often resolves within a few weeks to months.

Types of Bell’s Palsy

1. Mild Bell’s Palsy: Minimal facial paralysis with slight weakness in the muscles of the face.

2. Moderate Bell’s Palsy: Noticeable weakness with partial difficulty in facial movements.

3. Severe Bell’s Palsy: Complete facial drooping, inability to move the affected side of the face.

4. Recurrent Bell’s Palsy: Some patients may experience multiple episodes of facial paralysis over their lifetime.
