A cranial helmet, also known as a cranial orthosis, is a specialized device designed to help reshape a baby's head. It is often used for conditions like plagiocephaly, where one side of the head is flattened. The helmet gently applies pressure to specific areas of the skull, encouraging growth in the flatter regions. Typically made of lightweight materials, cranial helmets are custom-fitted to each child’s head. They are usually worn for several months, depending on the severity of the condition and the child's age. Regular follow-ups with a healthcare provider ensure proper fit and monitor progress during treatment.
