Figure 8. Correlation between longitudinal impedance data and fibrous capsule in an 82-year-old woman (Case 1L) who underwent cochlear implantation with an AB perimodiolar HiFocus electrode.

Figure 8

(A) Longitudinal impedance of sixteen electrodes. The bold line represents the longitudinal impedance level of electrode fifteen (E15). (B) post-mortem x-ray showing AB perimodiolar HiFocus electrode.

The large arrow marks electrode fifteen. Adjacent to the electrode there is an area of relatively decreased opacity representing new bone formation (NBF, small arrows).

Low (C) and high (D) magnification view of histological H&E section corresponding the position of electrode 15 (*); arrow showing the outline of the fibrous sheath.
