Itchy ears in infants always scratching the ears may be caused by localized skin uncleanliness, and no special treatment is needed. It may also be caused by eczema of the external auditory canal, cerumen impaction and other diseases, which need to be treated with medication, general measures to regulate, and if necessary, surgery. 1. Localized uncleanliness: When the saliva or milk stains of infants flow into the ear area and irritate the skin of the ear area, it will appear that the ear is itchy and always scratching the ear. You can use a warm washcloth or a cotton swab dipped in saline to help your child clean the ear. 2. Eczema of the external auditory canal: manifested as itchy ears, flaking, pimples, localized skin redness and swelling. You can use moisturizing cream or topical glycerin lotion under doctor’s guidance to relieve the symptoms. 3. Cerumen impaction: Infants with cerumen impaction may have itchy ears and keep scratching the ears with their hands. The doctor will remove the cerumen by cerumen hooking, flushing or suctioning. For tympanic membrane perforation, cerumen can be removed surgically under a microscope and treated with cerumen repair. Infants are advised to seek prompt medical attention and follow the doctor’s instructions to choose the appropriate treatment.
