Conference paper

Zusammenfassung

Die endokochleäre Implantation einer Elektrode bedeutet für beidseitig sensorisch ertaubte Menschen die einzige Hoffnung, wieder akustisch Umwelteindrükke wahrzunehmen; andererseits beinhaltet dieses Vorgehen die Gefahr, noch restliche vitale neuronale Strukturen zusätzlich zu schädigen und so diesen Hoffnungsschimmer endgültig zunichte zu machen. Im folgenden sollen die bisherigen Ergebnisse über die Reaktion endokochleärer Strukturen auf die Elektrode übersichtsartig dargestellt und zusammengefaßt werden. Systematisch lassen sich zwei denkbare Schädigungsmechanismen unterscheiden: Zum einen die mechanische Traumatisierung durch die Elektrode selbst, zum anderen die indirekte Schädigung über die applizierten Reizstromstärken. Beide Formen können in eine akute und in eine chronisch-protrahierte Variante unterteilt werden.
