Evaluating Cochlear Stimulation During Awake Ear Surgery (TONES Study)

This study is looking at whether short electrical signals can be heard by adults who are having ear surgery while awake. Researchers will use electrical extracochlear stimulation, which involves placing electrodes on the middle ear surface. The main goal is to see if you can accurately hear different sound frequencies from these electrical signals. You might be able to join if you are 18 or older and are scheduled for awake ear surgery that exposes the middle ear, such as for a tympanostomy tube, tympanoplasty, or stapes surgery. The study is currently unclear on its recruitment status and plans to enroll 18 participants.

Study design
This is an interventional study with a planned enrollment of 18 participants. It will investigate the feasibility of electrical stimulation of the cochlea for hearing restoration.
What's involved
You would provide real-time feedback on any auditory sensations and perceptions during a brief study procedure performed during your ear surgery.
Compensation
Not stated in the trial record.
Follow-up
Stimulation discrimination is measured at the time of the study procedure.

  • Stimulation discriminationTime of study procedure

    Accuracy of comparison of paired stimulation presentations as indicated by subject. This will be measured using a same-different task, where two stimulation paradigms are compared. The participant will be presented two consecutive stimuli, randomized to be the same or different. The participant will verbalize whether they felt the stimuli were the same or different. This will be repeated five times and graded on a percentage scale.
