[Practically relevant electrodiagnosis in facial and recurrent nerve pareses. A review]

Following a general description of pathophysiological changes of an injured peripheral nerve, a survey is presented in which those electrodiagnostic tests that are of practical relevance today in cases of facial and recurrent nerve pareses, are defined and the methods used are described (electromyography, neuromyography, blink reflex, reflex myography of the larynx). Typical electrodiagnostic findings are explained and demonstrated, using examples from our own case material. The relative merits and diagnostic efficiency of separate and combined findings are discussed.
