Stimulating the Cochlear Apex Without Longer Electrodes: Preliminary Results With a New Approach.

ABSTRACT:

Objective

To investigate a new surgical and signal processing technique that provides apical stimulation of the cochlea using a cochlear implant without extending the length of the electrode array.

Patients

Three adult patients who underwent cochlear implantation using this new technique.

Interventions

The patients received a cochlear implant. The surgery differed from the standard approach in that a ground electrode was placed in the cochlear helicotrema via an apical cochleostomy rather than in its typical location underneath the temporalis muscle. Clinical fitting was modified such that low frequencies were represented using the apically placed electrode as a ground.

Main outcome measures

Pitch scaling and speech recognition.

Results

All surgeries wer
