Myomodulation with HA fillers: a novel non-surgical therapy for facial paralysis

Hyaluronic fillers are commonly used for filling static wrinkles and lines and restoring volume in specific regions of the face. In recent years, another function has been observed, namely influencing muscle balance and elasticity of facial muscles. Depending on the method of injecting the hyaluronic filler, the activity of a specific muscle group can be strengthened or weakened. Myomodulation can be considered an innovative method for treating patients with facial nerve paralysis. Currently, there is a lack of literature data on this method for treating paralysis patients, and there is scant information on myomodulation with hyaluronic fillers. For this reason, this clinical case aims to present an alternative method for treating a patient with facial nerve paralysis using the myomodulatory action of hyaluronic fillers. Following a detailed history and clinical assessment of the case, a plan was made for injecting hyaluronic fillers, considering the different anatomical zones, muscle locations, and injection depths. As a result, a more balanced and aesthetic appearance was achieved by reducing the activity of compensatory hyperactive muscles and improving the overall condition of facial muscles and structure both in motion and at rest. It can be proposed that myomodulation with hyaluronic fillers is an effective way to treat patients with facial nerve paralysis, as unlike surgical treatment methods, it has a short recovery period and provides long-lasting and satisfactory results, thus improving the quality of life for these patients. However, further studies and investigations are required to improve the quality of life of patients with facial paralysis treated with hyaluronic fillers, as well as to determine the exact mechanism of action of the technique.
