According to the results reported on ClinicalTrials.gov, this trial enrolled 20 people, and all 20 completed the study — none dropped out. The trial involved a single group of participants who received a cochlear implant (a device surgically placed in the ear to help with hearing loss). The study was measuring something called "voltage tomography" — a technique that uses electrical signals to gather information about how the implant's electrode array sits inside the ear after it is inserted. Researchers were also looking for any instances of what is called a "tip foldover," which is when the tip of the electrode array bends back on itself during insertion rather than sitting correctly. The reported data shows that out of 20 participants, measurements were recorded for 19, with 1 participant noted separately across two different measurement categories. This pattern appears twice in the reported figures (19 and 1, repeated). The data was described as being gathered for "retrospective analysis," meaning it was collected to build a reference set of measurements for future comparison purposes. No further breakdown of what the voltage tomography readings showed in detail was included in the submitted results data. It is worth noting that because this trial was primarily collecting reference data rather than testing one treatment against another, the reported numbers reflect how many people had measurements taken rather than a treatment outcome in the traditional sense. Any details beyond the participant counts were not reported in the structured results submitted to ClinicalTrials.gov. These are the results as reported to ClinicalTrials.gov.

Who might be able to join this trial:
- You meet the requirements set by the implant centre to receive a specific type of cochlear implant (Cochlear Nucleus CI512, CI422, CI522, or CI532)
- You are 18 years old or older at the time of receiving the implant
Who may not be able to join:
- You have previously received a specific type of device called a Nucleus 24 ABI
- You have medical or mental health conditions that make it unsafe for you to have surgery or general anaesthesia (being put fully to sleep during an operation)
- You have a blockage, unusual shape, or other problem with the inner ear (cochlea) that may prevent the implant from being fully inserted, as confirmed by a doctor's examination
- You are unwilling or unable to follow all of the requirements of the study
