Symptoms of Facial Synkinesis
Facial synkinesis presents a spectrum of symptoms, often varying significantly between individuals. The hallmark of this condition is involuntary muscle movements, where actions like smiling trigger unintended contractions, such as eye closure. 1 This leads to noticeable facial asymmetry, as one side of the face moves differently than the other, hindering the ability to express emotions clearly and perform routine activities like speaking and eating. Furthermore, some individuals experience discomfort or pain stemming from these abnormal muscle contractions.
