Bell's Palsy Specialists in Indiranagar, Bengaluru, Karnataka

What is Bell's Palsy?

Bell's palsy is a condition causing sudden, temporary weakness or paralysis of the muscles on one side of the face, resulting from dysfunction of the facial nerve that controls these muscles. The exact trigger is often unclear, though it is widely believed to involve inflammation and swelling of the facial nerve, frequently linked to a viral infection, which compresses the nerve as it passes through a narrow bony canal in the skull. Symptoms typically develop quite suddenly, often over the course of a single day, and can be alarming due to their resemblance to the facial drooping seen in stroke, making prompt medical evaluation important to distinguish between the two. Unlike stroke, Bell's palsy does not usually affect other body functions such as limb strength or speech comprehension, and it is generally not associated with any long-term underlying brain condition. The majority of people with Bell's palsy experience significant or complete recovery within a few weeks to months, particularly with prompt treatment, though a small proportion have some lasting weakness.

Causes of Bell's Palsy

The exact cause is often unclear, but Bell's palsy is believed to result from inflammation and swelling of the facial nerve, frequently associated with reactivation of a dormant herpes simplex virus infection, though other viral infections have also been implicated. The swollen nerve becomes compressed as it passes through a narrow bony canal within the skull, impairing its ability to transmit signals to the facial muscles. Risk factors include pregnancy, diabetes, upper respiratory infections, and a family history of the condition, though many cases occur in people with no identifiable risk factors.

Symptoms of Bell's Palsy

Sudden weakness or paralysis on one side of the face, drooping of the mouth or eyelid, difficulty closing one eye, drooling, loss of taste on the front of the tongue, increased sensitivity to sound in one ear, pain around the jaw or behind the ear, difficulty making facial expressions on the affected side

Treatment & Types of Bell's Palsy in Indiranagar, Bengaluru, Karnataka

Treatment typically involves a course of corticosteroids started as early as possible to reduce nerve inflammation and improve the chances of full recovery, sometimes combined with antiviral medication if a viral cause is suspected. Protecting the affected eye, which may not close fully, using lubricating eye drops and an eye patch at night is important to prevent injury and dryness-related complications. Physical therapy exercises for the facial muscles can support recovery, particularly for those with more significant or prolonged weakness.
