Cochlear Implant Fitting Profiles in Children with Congenital Cytomegalovirus: One-Year Longitudinal Comparison with GJB2-Related Hearing Loss

Background/Objectives: Congenital cytomegalovirus (cCMV) infection is a major cause of paediatric sensorineural hearing loss and may involve peripheral and central auditory pathways. This study investigated longitudinal cochlear implant (CI) fitting parameters in children with cCMV-related hearing loss, including the influence of MRI-detectable brain abnormalities, using GJB2-related hearing loss as a reference.
