Cranial orthosis is a type of medical device designed to correct or manage abnormal head shapes in infants. It is often used for conditions like plagiocephaly, where one side of the head is flattened. The orthosis gently guides the growth of the skull into a more typical shape over time. The device is custom-fitted to the child's head and is typically worn for several months. Regular follow-up appointments with a healthcare provider are necessary to monitor progress and make adjustments. Cranial orthosis is a non-invasive treatment option that can help improve the appearance of the head and support healthy development.
