Figure Legends
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.
