Bell's palsy, also known as facial nerve palsy, is one of the most common causes of sudden facial weakness or facial drooping. It occurs when the facial nerve (the seventh cranial nerve) becomes inflamed, affecting the muscles on one side of the face.
What Causes Bell's Palsy?
Bell's palsy may occur due to:
A viral infection.
Swelling of the facial nerve within the bony facial canal.
In many cases, no clear underlying cause can be identified.
Symptoms of Bell's Palsy
Sudden facial drooping on one side.
Difficulty closing one eye.
Drooling.
Weakness of the facial muscles.
Changes in the sense of taste in some cases.
How Is Bell's Palsy Treated?
Treatment depends on early diagnosis and usually includes anti-inflammatory medications, eye protection to prevent dryness, and physical therapy when needed.
Why Is Early Treatment Important?
Most patients with Bell's palsy recover well when treatment begins early. If you notice sudden facial weakness or facial drooping, you should consult a neurosurgeon or neurologist as soon as possible for proper evaluation and treatment.
