title: [Oculo-auricular phenomenon and its value in neurologic diagnosis].
abstract: The oculoauricular phenomenon is a synergism between an external eye muscle, the m. rectus lateralis, and the facialis innervated m. retroauricularis. In the neurological diagnostic this phenomenon permits a differentiation between the abducens nerve paresis of peripheral and of nuclear origine. In addition to this electromyographic examination from the m. retroauricularis can discover disturbances of the neuromuscular transmission and facilitate an early prognostic estimation of peripheral facialis paresis.
