Cochlear Implantation in Children With Asymmetric Hearing Loss or Single-Sided Deafness Clinical Trial
NCT04793412 · View on ClinicalTrials.gov ↗
Study Summary
This is a two-phase study that compares performance growth pre-implant with current hearing aid (HA) technology versus post-implant with a cochlear implant (CI) in children with either asymmetric hearing loss (AHL) or single-sided deafness (SSD). Post-implant performance with a CI alone is expected to outperform pre-implant performance with a HA. The study also evaluates the effectiveness of bimodal hearing defined as a CI in the poor ear and a HA in the better ear for AHL or a CI in the poor ear and normal hearing in the better ear for SSD compared to pre-implant performance. The study examines factors contributing to CI outcomes.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04793412
The ClinicalTrials.gov registry entry for NCT04793412 describes a study currently listed as active not recruiting. It is categorized as NA, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 80 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is Washington University School of Medicine, which has 1,036 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 3 conditions, with Unilateral Deafness appearing as the primary indexed condition, and to 1 intervention — of which Cochlear Implant is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04793412 reports 5 study locations spanning 5 distinct geographic areas — top geographies include California, Minnesota, Missouri. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
