Abstract A method and a system for detecting a plurality of health conditions of a cochlea during insertion of an electrode array is described. The method comprising; applying a plurality of acoustic stimulations, and where each of the plurality of acoustic stimulations includes a tone burst including multiple acoustic pulses modulated at a tone of one frequency, arranging an electrocochleography probe to an outer wall of the recipient's cochlea, measuring via the electrocochleography probe a plurality of cochlea baseline responses based on the plurality of acoustic stimulations, before insertion of the electrode array into the recipient's cochlea, measuring continuously via the electrocochleography probe a plurality of cochlea responses based on the plurality of acoustic stimulations, during insertion of the electrode array into the recipient's cochlea, determining a plurality of electrical response differences between the plurality of cochlea baseline responses and the plurality of cochlea responses, respectively, determining a plurality of health conditions of the cochlea during insertion of the electrode array based on the plurality of electrical response differences.
