Cochlear Implantation in Children With Asymmetric Hearing Loss or Single-Sided Deafness Clinical Trial (NCT04793412)

๐Ÿ”ต Active, Not Recruiting Observational / Diagnostic โš™๏ธ Medical Device Protocol Sponsor: Washington University School of Medicine

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

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.
