Indeed, X-ray and CT scan performed on the same day confirmed that explantation had taken place with the electrode array lying in the EAC (Figures 1 and 2).
Coronal CT scan of the right temporal bone confirming explantation had taken place with the electrode array coiled up in the external auditory canal.

Embedding the electrode array, diseased tissue extended into the mastoid cavity through posterior tympanotomy (Figures 3 and 4).
The right external ear canal and mastoid cavity separated by the bony posterior canal wall W is shown with the explanted electrode array in situ. Cholesteatoma diseased tissue which is embedding a part of the explanted electrode array is seen in the middle/external ear E and mastoid M and is connected through the posterior tympanotomy (arrow).
