Synkinesis between facial nerve and oculomotor nerve. A case report.

We present a case history of a young man suffering from a facial-oculomotor synkinesis. The findings speak in favour of an acquired synkinesis due to trauma. Most probably the injury occurred in the midbrain, in the area of the vertical gaze control center and/or the area of the levator palpebrae motoneurons. A congenital synkinesis due to embryonic malformation seems to be unlikely, because at birth no restriction of the eye-ball motility was present.
