Systems and methods for detecting a scalar translocation of an electrode lead within a cochlea of a cochlear implant patient

A system comprising:

• at least one physical computing device that, in real time during an insertion procedure of an electrode lead included within a cochlear implant system into a cochlea of a cochlear implant patient:
• tracks trauma occurring to the cochlea during the insertion procedure by performing a sequence of scalar translocation determination operations each including
• detecting, by way of an electrode nearest a distal end of the electrode lead at a first time during the insertion procedure while the electrode is positioned at a first location along an insertion path of the electrode lead into the cochlea, a first evoked response that occurs in response to acoustic stimulation applied to the cochlear implant patient,
• detecting, by way of the electrode at a second time during the insertion procedure while the electrode is positioned at a second location along the insertion path of the electrode lead into the cochlea, a second evoked response that occurs in response to additional acoustic stimulation applied to the cochlear implant patient,
• determining at least one of an amplitude change between the first and second evoked responses and a phase change between the first and second evoked responses,
• determining, based on the at least one of the amplitude change and the phase change, whether a scalar translocation of the electrode lead from one scala of the cochlea to another scala of the cochlea has occurred, and
• determining, if the determination of whether the scalar translocation of the electrode lead has occurred indicates that the scalar translocation of the electrode lead has occurred, that trauma associated with the scalar translocation has occurred to the cochlea;
• provides a user interface for use by a user associated with the at least one physical computing device;
• and
• provides, to the user by way of the user interface, information representative of the tracked trauma occurring to the cochlea during the insertion procedure.

A method comprising:

• detecting, by a scalar translocation detection system and by way of an electrode configuration including at least one electrode disposed on an electrode lead included within a cochlear implant system and while the electrode configuration is positioned at a first location along an insertion path of the electrode lead into a cochlea of a cochlear implant patient, a first evoked response that occurs in response to acoustic stimulation applied to the cochlear implant patient;
• detecting, by the scalar translocation detection system and by way of the electrode configuration while the electrode configuration is positioned at a second location along the insertion path of the electrode lead into the cochlea, a second evoked response that occurs in response to additional acoustic stimulation applied to the cochlear implant patient;
• determining, by the scalar translocation detection system, at least one of an amplitude change between the first and second evoked responses and a phase change between the first and second evoked responses;
• and
• determining, by the scalar translocation detection system based on the at least one of the amplitude change and the phase change, whether a scalar translocation of the electrode lead from one scala of the cochlea to another scala of the cochlea has occurred.
