Facial Palsy (Bell's Palsy)

Overview

Facial Palsy, often referred to as Bell's Palsy, is a condition that causes a sudden, temporary weakness or paralysis of the muscles on one side of your face. This happens when the facial nerve, which controls your expressions and movements, becomes swollen, inflamed, or compressed. In India, many people mistakenly fear it is a permanent stroke, but with the right medical care, most patients find high recovery rates. It can affect anyone regardless of age, though it is frequently seen in adults with diabetes or those recovering from viral infections. At Sanjeevi Hospital, we understand how distressing it can be to lose control over your facial expressions or smile. Our neurology department focuses on rapid intervention to reduce nerve swelling, ensuring the best possible chance for a full and symmetric recovery. Early treatment within the first 72 hours is vital to prevent long-term complications and help you regain your natural look and confidence quickly.

Symptoms to watch for

• Sudden weakness or total paralysis on one side of the face appearing over hours to days.
• Drooping of the corner of the mouth, making it difficult to smile or show teeth.
• Difficulty closing one eyelid, which can lead to dryness or irritation of the eye.
• Drooling from the side of the mouth while drinking or eating.
• Increased sensitivity to loud noises in the ear on the affected side.
• A change in the sense of taste, specifically on the front part of the tongue.
• Pain or discomfort around the jaw or behind the ear on the side of the weakness.
• Excessive tearing or a very dry eye due to the inability to blink properly.
• Difficulty making facial expressions like frowning, squinting, or raising eyebrows.

Causes & risk factors

• Viral infections such as the herpes simplex virus (the same virus that causes cold sores).
• Inflammation or swelling of the seventh cranial nerve due to immune system responses.
• History of upper respiratory tract infections like the common cold or flu.
• Higher risk during pregnancy, especially during the third trimester or the first week after giving birth.
• Complications arising from diabetes, which can affect nerve health and blood circulation.
• Exposure to certain environmental triggers like sudden cold drafts (as seen in local seasonal changes).
• Involvement of the Varicella-zoster virus, which is responsible for chickenpox and shingles.
• Physical stress or a weakened immune system making the nerves more vulnerable to inflammation.

Diagnosis

• A thorough physical examination where the doctor asks you to move your facial muscles by blinking, smiling, or lifting your brow.
• Medical history review to rule out other conditions like a stroke or tumours that mimic facial weakness.
• Electromyography (EMG) to measure the electrical activity of the facial muscles and confirm nerve damage.
• Imaging tests like an MRI or CT scan to ensure there are no other structural issues pressing on the nerve.
• Blood tests to check for underlying conditions such as diabetes or infections like Lyme disease.
• Neurological assessment to check other cranial nerves and ensure the issue is localized to the facial nerve.
• Ear examination to rule out middle ear infections or shingles of the ear (Ramsay Hunt Syndrome).

Treatment options

Prevention & self-care

• Manage blood sugar levels effectively if you have diabetes to protect nerve health.
• Maintain a healthy immune system through balanced Indian nutrition, including vitamin-rich foods like leafy greens and citrus fruits.
• Protect your face and ears from extreme cold or sudden temperature drops by wearing scarves or earmuffs.
• Practice stress-management techniques like yoga or meditation to keep your body's defenses strong.
• Maintain good hygiene to avoid viral infections that could trigger nerve inflammation.
• Follow up regularly with your physician for routine check-ups and early detection of risk factors.
• Seek prompt treatment for any ear or respiratory infections to prevent them from spreading.
• Stay hydrated and ensure adequate rest during periods of high physical or emotional stress.
