Can facial paralysis causing corner-of-the-mouth atrophy be restored?

In general, whether facial paralysis-induced corner-of-the-mouth atrophy can be restored depends on the specific condition. If the atrophy is mild, recovery is usually possible; however, if the atrophy is severe, the likelihood of recovery is significantly reduced. In case of discomfort, prompt medical attention is recommended. The detailed analysis is as follows:

When the corner-of-the-mouth atrophy caused by facial paralysis is in the early stage or is mild, facial nerves and muscle tissues have typically not suffered severe damage. In such cases, treatments such as acupuncture, physical therapy, rehabilitation training, and appropriate facial muscle exercises can promote nerve regeneration and restore muscle function, thereby improving or even completely reversing the atrophy.

If the corner-of-the-mouth atrophy due to facial paralysis has progressed to a more severe stage, full recovery becomes much more difficult. At this point, the facial nerves may have sustained serious damage, and the muscle tissue may have already undergone atrophy and fibrosis. The damage to nerves and muscles may have become irreversible, making it difficult to fully restore the original condition even with treatment.

To prevent conditions such as facial paralysis and corner-of-the-mouth atrophy, it is advisable to maintain moderate activity of the facial muscles in daily life and avoid maintaining the same expression or posture for prolonged periods. Additionally, ensuring adequate sleep and maintaining healthy lifestyle habits can help enhance the vitality and elasticity of facial nerves and muscles.
