A surgical arrangement for use in a multi-step surgical process to implant a cochlear implant system in a patient, the arrangement comprising: a control module configured to control the multi-step surgical process including directing: i. an acoustic stimulation module to deliver acoustic stimulus signals to the ear canal of the patient, and ii. an electrical stimulation module representing the components of the cochlear implant system including an electrode array configured to deliver electrical stimulation signals to the cochlea being implanted; iii. one or more recording electrodes configured to obtain stapedius reflex response measurements from the stimulus signals; iv. a stapedius reflex response measurement module within the control module and configured to determine from the stapedius reflex response measurements an intraoperative baseline value stapedial reflex response of the patient for the multi-step surgical process; and wherein the stapedius reflex response measurement module is configured to monitor the intraoperative baseline value stapedial reflex response during the multi-step surgical process, and the control module is further configured to notify a surgeon to stop at a given step if the intraoperative baseline value stapedial reflex response changes more than a safe change threshold value. a control module configured to control the multi-step surgical process including directing: i. an acoustic stimulation module to deliver acoustic stimulus signals to the ear canal of the patient, and ii. an electrical stimulation module representing the components of the cochlear implant system including an electrode array configured to deliver electrical stimulation signals to the cochlea being implanted; iii. one or more recording electrodes configured to obtain stapedius reflex response measurements from the stimulus signals; iv. a stapedius reflex response measurement module within the control module and configured to determine from the stapedius reflex response measurements an intraoperative baseline value stapedial reflex response of the patient for the multi-step surgical process; and i. an acoustic stimulation module to deliver acoustic stimulus signals to the ear canal of the patient, and ii. an electrical stimulation module representing the components of the cochlear implant system including an electrode array configured to deliver electrical stimulation signals to the cochlea being implanted; iii. one or more recording electrodes configured to obtain stapedius reflex response measurements from the stimulus signals; iv. a stapedius reflex response measurement module within the control module and configured to determine from the stapedius reflex response measurements an intraoperative baseline value stapedial reflex response of the patient for the multi-step surgical process; and wherein the stapedius reflex response measurement module is configured to monitor the intraoperative baseline value stapedial reflex response during the multi-step surgical process, and the control module is further configured to notify a surgeon to stop at a given step if the intraoperative baseline value stapedial reflex response changes more than a safe change threshold value.
