Facial synkinesis is a chronic condition occurring in up to half of people who experience facial nerve paralysis, according to Dr. Jessyka Lighthall of the Penn State Health Facial Nerve Clinic. The condition arises when nerves misfire during regrowth, leading to involuntary muscle contractions. While no cure exists, clinicians manage symptoms through injections, specialized facial nerve therapy, and, in specific cases, surgery to restore symmetry and function.
Understanding the Mechanics of Facial Synkinesis
Synkinesis develops when facial nerves, damaged by trauma, infection, or conditions like Bell’s palsy, fail to reconnect properly. Instead of targeting the intended muscle, nerves “misfire,” causing cross-talk between different areas of the face. Dr. Lighthall, division chief of facial plastic and reconstructive surgery at Penn State Health, describes this as abnormal nerve regrowth. For the patient, this manifests as involuntary movements, such as an eye closing while the patient is eating, laughing, or pursing their lips.
Brittani Snyder, a 36-year-old real estate agent from York, Pennsylvania, experienced this firsthand after a tick bite led to a diagnosis of Lyme disease and subsequent facial nerve damage. She describes the sensation as being “fish-hooked,” noting that her facial muscles were especially pulling to the right, creating significant asymmetry.
Did you know?
Facial synkinesis is not limited to Bell’s palsy. It can occur following any facial nerve injury, including those caused by tumors, strokes, or physical trauma.
Multidisciplinary Approaches to Symptom Management
Because there is no known cure for synkinesis, treatment focuses on quality of life and functional improvement. At the Penn State Health Facial Nerve Clinic, which recently celebrated its 10th anniversary, care is highly individualized. Dr. Lighthall utilizes small, precise doses of Botox to relax overactive muscles on both the affected and unaffected sides of the face. This process aims to harmonize facial movement and reduce the intensity of involuntary twitches.
Complementing medical intervention is facial neuromuscular retraining, led by speech-language pathologist Nicole Fisher. Fisher works with patients to develop customized exercise programs designed to lengthen tight muscles and increase their range of motion. For patients like Snyder, these daily exercises are a cornerstone of recovery, helping to regain control over muscles that have become overstimulated.
The Psychosocial Impact of Facial Nerve Disorders
The challenges of facial synkinesis extend far beyond physical movement. According to Fisher, the visible nature of the condition carries a significant emotional toll. Many patients report feeling self-conscious in professional or social settings, often avoiding activities like eating in public.
To address these needs, clinics are increasingly focusing on the “whole patient” experience. Penn State Health is expanding its support network by launching a new Facial Nerve Patient Support Group in the coming months. This initiative aims to connect individuals navigating similar diagnoses, providing a community for those dealing with the long-term realities of nerve damage.
Frequently Asked Questions
- Is facial synkinesis reversible? No, there is no known cure for the condition, as it results from permanent nerve miswiring. However, symptoms can be managed through injections and physical therapy.
- Why does my eye close when I eat? This is a classic sign of synkinesis, where “cross-talk” between nerves causes the eye muscle to activate unintentionally when you use your mouth muscles.
- Can Lyme disease cause facial paralysis? Yes, as seen in the case of Brittani Snyder, infections like Lyme disease can damage the facial nerve, leading to paralysis and subsequent synkinesis.
Consistency is key for neuromuscular retraining. Patients who adhere to daily, prescribed facial exercises often see more significant improvements in comfort and muscle control than those who do not.
