Abstract[English]
Techniques presented herein disambiguate Electrocochleography (ECochG) signal changes caused by either a moving electrode contact or an underlying shift in the change in the acoustic responsiveness of the cochlea by contemporaneously recording ECochG signals from at least two sites in the cochlea and tracking the position or movement of the stimulating assembly during surgery. The recorded ECochG signals, along with the position information, can be used to determine the cause of variations in the measured ECochG signals.[French]
La présente invention concerne des techniques qui désambiguïsent les modifications du signal d'électrocochléographie (ECochG) provoquées soit par un contact d'électrode mobile, soit par un changement sous-jacent de la modification de la réactivité acoustique de la cochlée, en enregistrant simultanément des signaux ECochG à partir d'au moins deux sites dans la cochlée et en suivant la position ou le déplacement de l'ensemble de stimulation pendant une intervention chirurgicale. Les signaux ECochG enregistrés, conjointement avec les informations de position, peuvent être utilisés pour déterminer la cause des variations des signaux ECochG mesurés.
