Craniosynostosis is a condition where one or more of the sutures in a baby’s skull close prematurely. This early fusion can restrict skull growth and affect the shape of the head. It can lead to increased pressure on the brain and may require medical intervention to correct. The exact cause of craniosynostosis is often unknown, but it can be associated with genetic syndromes or occur sporadically. Treatment typically involves surgery to allow for normal skull growth and to prevent potential complications. Early diagnosis and intervention are important for the best outcomes for affected infants.
