Bell’s Palsy
Bell's Palsy is a medical condition that causes sudden weakness or paralysis of the muscles on one side of the face. It happens when the Facial nerve (cranial nerve VII), which controls facial muscles, becomes inflamed or compressed.
What is a cranial nerve: A nerve that originates directly from the brain rather than from the spinal cord, carrying signals between the brain and different parts of the body. Humans have 12 pairs of cranial nerves, each with a specific function.
Key Features:
- Usually affects one side of the face.
- Can develop rapidly, often within hours.
- Some experience pain around the jaw or behind the ear.
- Causes facial drooping and difficulty closing the eye.
- Bell's palsy is temporary facial nerve weakness, not a progressive or life-threatening disease.
Causes and Triggers:
- Viral infections
- Nerve inflammation
- Physical trauma
- Health conditions that weaken the immune system
- Physical factors such as stress, sleep deprivation, or pregnancy
Treatments:
- Facial exercises, Massage therapy, Electrical stimulation
- Heat therapy, Education, Neuromuscular re-education
When to See a Physio?
Usually a week after onset, once severe pain reduces. Best results occur when you seek treatment promptly to prevent aberrant reinnervation and promote symmetrical facial recovery.
