Facial Paralysis Recovery: Which Areas Are the Hardest to Heal?

When it comes to recovering from facial paralysis, certain areas of the face tend to heal more slowly and less completely than others. Among these, the muscles located below the eye fissure are often the most challenging to restore. The most noticeable symptom in these cases is persistent mouth deviation, where the corner of the mouth remains uneven even after other functions have improved.

Understanding the Recovery Timeline

Recovery from facial paralysis typically begins around the second week after the onset of symptoms. By the second to third week, many patients begin to notice more visible improvements. However, the sequence of recovery follows a distinct pattern: the muscles above the eye fissure usually regain function first.

Early Signs of Recovery

The initial recovery often involves the forehead and eye-related muscles. Patients may find that they can blink, raise their eyebrows, or frown before other areas show improvement. These early signs are encouraging and indicate that the healing process has begun.

Challenges in Later Recovery Stages

As recovery progresses, the muscles below the eye fissure—responsible for actions like whistling, puffing the cheeks, or precise mouth movements—tend to lag behind. Even when most facial functions return, subtle imbalances such as a slight tilt in the mouth during smiling or speaking can persist. This residual asymmetry is one of the most common long-term effects of facial paralysis.

Full Recovery Expectations

For many patients, full recovery can occur within one to two months. However, in more severe cases, the healing process may extend from two months up to a full year. The duration largely depends on the extent of nerve damage and the individual's overall health and response to treatment.

While most individuals experience significant improvement over time, the area around the mouth remains the most difficult to fully restore. Consistent therapy and medical guidance are essential for maximizing recovery outcomes and minimizing long-term effects.
