To accomplish this goal, the stimulating contacts on both designs are located on the medial surface of the electrode and two very different strategies are used to position the electrode closer to the spiral ganglion in situ.
These studies examined electrodes with and without insulating carriers, with stimulating contacts in different orientations, and with these contacts in varying proximity to the spiral ganglion.
Thus, even minor damage to the modiolar wall may cause loss of spiral ganglion cells as a result of direct trauma and could also provide a pathway for the spread of infection from the middle ear, along the CI carrier, and into the cerebrospinal fluid, potentially leading to severe medical complications.
