This 34 year-old patient complained of pronounced phenomena. Before the operation, only 1 1/2 maxillary teeth are exposed when smiling broadly on the right side, the corner of the mouth also tends to point downward when smiling ("negative vector") and an unwanted partial eye closure may be noticed. Immediately after selective neurectomy and myectomy, the first improvements can be seen: now 3 maxillary teeth are exposed when smiling, the corner of the mouth has a "positive vector" (points upwards) and the eye is clearly more relaxed. In order to reorganize the mimic function, intensive professional as well as additional independently performed exercise therapy should follow in order to achieve an optimal result.
