During regeneration and repair of the facial nerve, some neural fibers may take an unusual course and connect to neighboring muscle fibers. This aberrant reconnection produces unusual neurologic pathways. When voluntary movements are initiated, they are accompanied by involuntary movements (eg, eye closure associated with lip pursing or mouth grimacing that occurs during blinking of the eye). The condition in which involuntary movements accompany voluntary movements is termed synkinesis.
