Jaundice affects hearing and the recovery time is uncertain, depending on the severity of the condition and whether the child receives active treatment. Hearing problems in patients with jaundice often mean that kernicterus is present, which indicates neurological damage, and the likelihood of recovery is relatively low. Patients need to treat their children actively under the guidance of specialists, and also need to undergo hearing and speech rehabilitation training. Kernicterus, also known as bilirubin encephalopathy, is a brain damage induced by bilirubin deposition in the basal neurons and the nuclei of the brainstem. Bilirubin encephalopathy can be categorized into four phases: the warning phase, the spasmodic phase, the recovery phase, and the sequelae phase, and the hearing impairment belongs to the sequelae phase. The effects of kernicterus on hearing are often severe, and parents need to pay attention and treat their children as soon as possible.
