Facial paralysis warning: Early diagnosis key to recovery

WISE NEWS PRESS / ISTANBUL, TÜRKİYE

Facial paralysis, caused by damage to the facial nerve that controls facial muscles, can lead to loss of movement and expression, and experts warn that early medical intervention is critical for recovery.

The condition typically affects one side of the face and presents with symptoms such as drooping at the corner of the mouth, inability to close the eye, and weakened facial expressions. Dr. Daryush Heydari, Neurology Specialist at Istanbul Okan University Hospital, says patients should seek medical care immediately when these symptoms appear.

Bell’s palsy is the most common cause

According to Dr. Heydari, the most frequent cause of facial paralysis is Bell’s palsy, which occurs when the facial nerve swells within its bony canal and its blood supply is impaired. This condition often develops following viral infections.

However, facial paralysis-like symptoms may also result from trauma, middle ear infections, tumors, or stroke. For this reason, patients presenting with facial weakness should undergo a detailed ear examination and comprehensive assessment of the facial nerve.

High-risk groups should be monitored closely

Clinical observations show that facial paralysis affects men and women at similar rates, but the risk is higher in pregnant women. Individuals with diabetes and thyroid disorders are also more likely to develop facial paralysis, making early diagnosis especially important for these groups.

Surgery is rarely required

Most cases of facial paralysis can be treated successfully without surgical intervention. Facial muscle exercises and massage help support recovery, while protecting the face from cold and windy weather is also recommended.

Dr. Heydari emphasizes that the widespread belief that cold weather directly causes facial paralysis has no scientific basis. “Cold exposure does not directly lead to facial paralysis, but it may contribute indirectly through certain triggering factors,” he explains.

Recovery depends on the severity of nerve damage

Recovery time varies depending on the degree of damage to the facial nerve. Mild cases may resolve within days, while more severe cases—treated with steroid medications to reduce inflammation and antiviral therapy—can take several months to heal.

Experts underline that early diagnosis and timely treatment play a decisive role in preventing permanent facial weakness and ensuring better long-term outcomes for patients.
