ABOUT THIS CONDITION
What is Bell's Palsy
Bell's palsy is a sudden weakness or paralysis of one side of the face caused by inflammation of the facial nerve. It typically develops over hours to a day or two, with patients noticing facial drooping, inability to close one eye, difficulty smiling on the affected side, drooling, loss of taste on the front part of the tongue and sometimes mild ear pain or sensitivity to sound. The exact cause is not always clear, but reactivation of certain viruses such as herpes simplex is thought to be a common trigger. Most patients recover completely within weeks to months, particularly when treated early with steroid therapy. A small proportion may have incomplete recovery. Diagnosis is clinical, but it is important to distinguish Bell's palsy from stroke and other serious causes. Treatment includes early steroid therapy, antiviral therapy in selected cases, eye protection, facial exercises and supportive care. Dr. Patnam Pravallika Reddy provides accurate diagnosis and complete care at Lux Hospitals, Hyderabad.
