In order to minimize the risk of inflammation, the wound is sterilely dressed after ear surgery. The wound is closed after about ten days. Until then, there is a risk of germs entering the wound and multiplying. It is therefore very important to observe hygiene measures. The dressing should not be changed independently for the first week. Hair washing is possible on the seventh day after the surgical procedure, immediately before the dressing change in the CenterPlast. The wound may only come into contact with water for a short time. Make sure that no soap residue remains on the scalp. The hair should be blow-dried with cold air. Wear the headband ordered for you until the dressing is changed in the CenterPlast.
