Electric ear test: can zaps help the deaf hear?
NCT ID NCT07402941
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tests if adults having awake ear surgery can hear short electrical pulses applied to a part of the inner ear. Researchers want to see if people can tell different frequencies apart. The results could help design better hearing implants. About 18 participants will be involved.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. Individual is ≥ 18 years old at the time of consent. 2. Individual is scheduled for awake ear surgery that will expose the middle ear (subannular tympanostomy tube placement, tympanoplasty, stapes surgery). 3. Individual is willing to complete intraoperative assessments of promontory stimulation. Exclusion Criteria: 1. Individual has had severe-to-profound hearing loss for more than 30 years. 2. Individual has congenital hearing loss (for the purpose of this study, onset prior to 2 years of age) 3. Ear canal will not accommodate a speculum with minimum outer diameter (OD) of 4.0 mm or other anatomic challenges present as determined by the study investigator 4. Hearing loss or auditory processing disorder of neural or central origin 5. Active middle ear infection 6. History of cholesteatoma treated within the past 2 years 7. Ossification of the cochlear or other previously identified cochlear anomaly 8. Prior major head trauma (stroke, hemorrhage, traumatic brain injury) within past 2 years 9. Contralateral presence of cochlear implant 10. Individual is pregnant. 11. Individual is unable or unwilling to complete training for qualitative evaluation of promontory electrical stimulation. 12. A disability that could interfere with intraoperative evaluations as determined by study investigator. 13. Profound tinnitus 14. History of vertigo that would interfere with the planned investigation as determined by the principal investigator
