Lateral skull X-ray after trauma. The arrowhead points to the electrode which is curled in a 200-degree position. Comparing this with Figure 2 shows obvious migration of the electrode.

Skull X-rays (Figure 1) showed displacement of the left implant electrode when compared to the post-CI X-ray (Figure 2).
Lateral skull X-ray after initial cochlear implantation. The arrowhead points to the electrode which is curled in a 360-degree position, indicating its position in the basal and middle turn.

Computed tomography (CT) of the temporal bone showed ten of 22 electrodes out of the cochlear (Figure 3).
This is an intraoperative lateral skull X-ray taken after the electrode was advanced. The electrode resumed a similar position to Figure 2.

We first performed adhesiolysis of the middle ear and then advanced the electrode smoothly back through the round window with jeweller's forceps and intraoperative X-rays and NRT yielded a good result (Figure 4).
