Surgical technique protocol for cochlear implantation in post-meningitic ossified cochlea

A protocol for the order of choice of electrode and site of insertion in various cases of labyrinthitis ossificans depending on the degree of ossification is proposed. In the order of preference, it would be thus: 1. Cochlear implantation with the active electrode in the scala tympani of the basal turn; 2. Electrode in the scala vestibuli of the basal turn; 3. Anterograde insertion of the implant from the second turn; 4. Retrograde insertion of the implant from the second turn; 5. Insertion of a split array electrode and finally 6. Auditory brainstem implantation.
