(A) Current levels for this patient compared to other S8 and S12 Hybrid cochlear implant users measured one to three months after implantation, separated into those with stable hearing and those who developed hearing loss after activation. Red arrow indicates subject. The stable hearing group had less than 0.5 decibel per month increase in low frequency pure tone average (125, 250, 500, 1000 Hz), and the hearing loss group had greater than 30 decibel increase in low frequency pure tone average. Note that the approximate electrode position begins at 4 mm for S12 Hybrid patients and 6mm for S8 Hybrid patients. The shaded area indicates the range of programming levels for a group of Nucleus® Contour Advance™ implantees (Cochlear Ltd., Australia) for comparison.

(B) Electrode impedance measurements over time for this patient. Impedances obtained using the common ground electrode are shown for each of the 6 electrodes at the indicated time point relative to date of implantation (0 month).
