[Pathophysiologic observations of facial neuralgia].

The different etiology and pathogenesis of face-neuralgiae requires a spezific therapy of the respective illness. New aspects are formed in the last years in the so-called idiopathic neuralgia. She has good chances with the therapy through the Jannetta-operation. The evident mechanical lesion by compression, the ephaptic genesis and the special pain-characterization with trigger-attacks not support the "idiopathic". This is called "ictal neuralgia". The paper attempts pathophysiological to explain the specific pain. It shows aspects to the trigger mechanism, to the intensity of the pain and to the ictal pain-characterization.
