A method and apparatus for diagnosing the extent of survival of the peripheral sensori-neural elements within the inner ear of a patient by stimulating the patient with one or more pair of electrical stimulus signals having a known amplitude and inter-signal delay, and by measuring the electrical activity within the nervous system of the patient which results from these stimulus signals and comparing the activity which results from the second stimulus signal with the activity which results from the first stimulus signal.

A method of diagnosing the extent of survival of the peripheral sensori-neural elements with a patient, comprising the steps of: stimulating the inner ear of the patient with a first electrical stimulus signal and a second electrical stimulus signal having a first predetermined delay with respect to said first electrical stimulus signal; measuring the electrical activity within the nervous system of the patient which results from said first electrical stimulus signal and said second electrical stimulus signal having a first predetermined delays then stimulating the inner ear of the patient with said first electrical stimulus signal and said second electrical stimsulus signal having a second predetermined delay with respect to said first electrical stimulus signal; measuring the electrical activity within the nervous system of the patient which results from said first electrical stimulus signal and said second electrical stimulus signal having a second predetermined delay; and comparing the electrical activity within the nervous system of the patient which results from said first and second electrical stimulus signals with said first predetermined delay with the electrical activity within the nervous system of the patient which results from said first and second electrical stimulus signal with said second predetermined delay.
