Figure 1. MRI scan of cases with or without REP. Imaging of (a) showed typical REP in bilateral temporal lobes. Imaging of (b) showed no obvious sign of REP. MRI = magnetic resonance imaging; REP = radioactive encephalopathy.
Figure 2. Endoscopic imaging and CT scan of preoperative situation. Imaging of (a) showed intact TM and the posterior and upper wall of EAC, and localized ORNTB. Imaging of (b) showed intact TM and the posterior and upper wall of EAC, and diffuse ORNTB. Imaging of (c) showed perforated TM and the defects on the posterior and upper wall of EAC, and diffuse ORNTB. CT = computed tomography; TM = tympanic membrane; EAC = external auditory canal; ORNTB = osteoradionecrosis of the temporal bone.
Figure 3. Endoscopic imaging of electrode exposure and CT scan of postoperative situation. Imaging of (a) showed an exposed electrode in the right posterior wall of the external auditory canal 12 months after surgery. Imaging of (b) showed that the intracochlear electrode array was completely migrated 28 months after surgery. Imaging of (c) showed the right electrode’s position in cochlea with the protection of abdominal fat graft.
