Bell’s Palsy Overview
Bell’s palsy is a sudden, temporary weakness or paralysis of the muscles on one side of the face. It occurs when the facial nerve (cranial nerve VII), which controls facial expressions, becomes inflamed, swollen, or compressed. This condition can cause the affected side of the face to droop, and individuals may find it difficult to smile, blink, or close their eye.
The exact cause of Bell’s palsy isn’t always clear, but experts believe viral infections that inflame the facial nerve may be responsible. In many cases, symptoms appear overnight, creating a great deal of distress for those affected. However, most people begin to recover within a few weeks, with or without treatment.
Common symptoms of Bell’s palsy include:
- Sudden weakness or paralysis on one side of the face
- Drooping of the mouth or eyelid
- Inability to close the eye on the affected side
- Excessive tearing or dry eye
- Drooling
- Loss of taste, usually on the front two-thirds of the tongue
- Increased sensitivity to sound in one ear
- Pain around the jaw or behind the ear
Bell’s palsy can affect anyone, but it occurs most often in adults aged 15 to 60. While it can be alarming, it is not life-threatening and is not related to stroke, although the symptoms may look similar.
In South Africa, cases often present to GPs, clinics, and emergency units, especially due to the sudden onset of facial drooping. Healthcare workers must recognise symptoms early and provide reassurance — especially in rural areas with limited access to neurologists.
With early treatment, such as corticosteroids, many people experience full recovery. Supportive care, including eye protection, facial exercises, and in some cases antiviral medications, also plays an important role.
