Evaluation of Cochlear (Promontory) Stimulation During Awake Ear Surgery (TONES Study)

The goal of this interventional clinical study is to investigate the feasibility for minimally invasive electrical stimulation of the cochlea as a mechanism for hearing restoration. The main aims of the study are to: Establish comfortable and tolerable auditory thresholds Investigate the relationship between the position of stimulation, the stimulation parameters and the perceived frequency of any auditory sensation. This study will enroll patients undergoing middle ear surgery where a brief study procedure will be performed during the course or their surgery. Participants will provide real-time feedback on any auditory sensations and percepts.
