Zusammenfassung
Implantierbare Hörgeräte werden bei der Versorgung unterschiedlich bedingter Schwerhörigkeiten immer bedeutsamer. Das am häufigsten implantierte Mittelohrhörsystem ist die Vibrant Soundbridge (VSB, Fa. MED-EL, Innsbruck, Österrreich). Es haben sich, nach Erweiterung der Indikation, verschiedene neue Ankopplungsmöglichkeiten ergeben. In der vorliegenden Arbeit wird das Anregungsverhalten der VSB anhand der Literatur, vorliegender Felsenbeinversuche und mittels Berechnungen im Finite-Elemente-Modell (FEM) eingehend beleuchtet. Darüber hinaus wird auf wichtige Begleitumstände der Ankopplung, Übertragung und Messung eingegangen.
Abstract
Implantable hearing aids are not only gaining importance for the treatment of sensorineural hearing loss, but also for treatment of mixed hearing loss. The most frequently used active middle ear implant is the Vibrant Soundbridge (VSB) system (Fa. MED-EL, Innsbruck, Österrreich). Following widening of the spectrum of indications for the VBS, various new coupling systems have been established. Based on the literature, available petrosal bone investigations and finite element model (FEM) calculations, this article summarizes the current knowledge concerning mechanical excitation by the VSB. Important concomitant aspects related to coupling, transmission and measurement are also discussed.
