Einiges über die Entwicklung der klinischen Vestibularforschung während der letzten 25 Jahre, besonders bezüglich des Labyrinthfistelsymptoms und des Lagenystagmus

Abstract

The author gives an account of the attributions of Scandinavian investigators to the development of the labyrinth fistula symptom and positional nystagmus during a quarter of a century from 1917. At that time S. H. Mygind discovered the so called carotical fistula symptom, and during the following years Borries added the stasis fistula symptom. The clinical importance of the vascular fistula symptoms, to which the eyes-movements synchroneous with the pulse are included, have been treated in extensive treatises by Nylen 1923 and Lund 1933.The author describes two cases of labyrinth fistula recently operated, where among other things the vessels (V. jugularis, art. carotis) of one side of the neck have been isolated and compressed. The result of the different experiments makes the author accept a unitary theory for all the vascular or vasomotoric phenomena. Systole, as well as compression of the vessels of the neck, and stasis (straining, Bier's stasis, inhalation of amylnitrit) with certain exceptions caus...
