Abstract:
An exemplary monitoring system 1) monitors evoked responses that occur in response to acoustic stimulation during an insertion procedure in which a lead that is communicatively coupled to a cochlear implant is inserted into a cochlea of a patient, the monitoring comprising using an intracochlear electrode disposed on the lead to measure a first and a second evoked response at a first and a second insertion depth within the cochlea, the second insertion depth nearer to an apex of the cochlea than the first insertion depth, 2) determines that a change between the first evoked response measured at the first insertion depth and the second evoked response measured at the second insertion depth is greater than a predetermined threshold, and 3) determines, based on the determination that the change is greater than the predetermined threshold, that cochlear trauma has likely occurred at the second insertion depth.
