 This study investigated the progression of hearing loss in children with unilateral hearing loss, UHL, finding that almost half of these children experienced some degree of deterioration in hearing in one or both ears. The majority of deterioration occurred within the first four years following diagnosis, with the decrease stabilizing and showing a plateau in the last four years. Children with ENT external slash middle ear anomalies, inner ear anomalies, syndromic hearing loss, and hereditary slash genetic causes were found to be at higher risk for progressive hearing loss.
