A system comprising: a cochlear implant; a lead that is communicatively coupled to the cochlear implant and has a plurality of intracochlear electrodes disposed on a distal portion of the lead; and at least one physical computing device (104, 402, 502, 1500) that is configured to monitor evoked responses that occur in response to acoustic stimulation produced at a particular frequency during an insertion procedure in which the lead is inserted into a cochlea (200; 802) of a patient, the monitoring of the evoked responses comprising using an intracochlear electrode included in the plurality of intracochlear electrodes to measure a first evoked response at a first insertion depth (812-1; 1004-1; 1204-1) of the intracochlear electrode within the cochlea and a second evoked response at a second insertion depth (812-2; 1004-2; 1204-2) of the intracochlear electrode within the cochlea, the second insertion depth nearer within the cochlea to an apex of the cochlea than the first insertion depth, determine, during the insertion procedure, 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 determine, during the insertion procedure based on the determination that the change is greater than the predetermined threshold, that cochlear trauma has likely occurred at the second insertion depth of the intracochlear electrode within the cochlea. a cochlear implant; a lead that is communicatively coupled to the cochlear implant and has a plurality of intracochlear electrodes disposed on a distal portion of the lead; and at least one physical computing device (104, 402, 502, 1500) that is configured to monitor evoked responses that occur in response to acoustic stimulation produced at a particular frequency during an insertion procedure in which the lead is inserted into a cochlea (200; 802) of a patient, the monitoring of the evoked responses comprising using an intracochlear electrode included in the plurality of intracochlear electrodes to measure a first evoked response at a first insertion depth (812-1; 1004-1; 1204-1) of the intracochlear electrode within the cochlea and a second evoked response at a second insertion depth (812-2; 1004-2; 1204-2) of the intracochlear electrode within the cochlea, the second insertion depth nearer within the cochlea to an apex of the cochlea than the first insertion depth, determine, during the insertion procedure, 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 determine, during the insertion procedure based on the determination that the change is greater than the predetermined threshold, that cochlear trauma has likely occurred at the second insertion depth of the intracochlear electrode within the cochlea. monitor evoked responses that occur in response to acoustic stimulation produced at a particular frequency during an insertion procedure in which the lead is inserted into a cochlea (200; 802) of a patient, the monitoring of the evoked responses comprising using an intracochlear electrode included in the plurality of intracochlear electrodes to measure a first evoked response at a first insertion depth (812-1; 1004-1; 1204-1) of the intracochlear electrode within the cochlea and a second evoked response at a second insertion depth (812-2; 1004-2; 1204-2) of the intracochlear electrode within the cochlea, the second insertion depth nearer within the cochlea to an apex of the cochlea than the first insertion depth, determine, during the insertion procedure, 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 determine, during the insertion procedure based on the determination that the change is greater than the predetermined threshold, that cochlear trauma has likely occurred at the second insertion depth of the intracochlear electrode within the cochlea.
