This 22-year-old female patient suffered from synkinesis, a typical sequelae of a defect healing of the facial nerve after facial nerve palsy. When smiling, involuntary spasms of unintended muscle groups in the right side of the face occur. The corner of the mouth appears fixed by counterproductive muscle activity, the chin muscle tenses, and the eye involuntarily closes almost completely. In some patients, this can impair vision in everyday life (for example, when driving a car). After surgery by modified selective neurectomy, the face appears much more balanced and relaxed. The corner of the mouth has gained more freedom when smiling, the cramping around the chin and the involuntary closure of the eyes have improved.
