Craniosynostosis is a rare condition in babies in which one or more of the skull’s fibrous joints, called sutures, close earlier than normal. Since the skull cannot expand normally in the affected area, it may lead to an unusual head shape and, in some cases, increased pressure inside the skull. The condition can be present at birth and may affect a single suture or multiple sutures. Common types include sagittal, coronal, metopic, and lambdoid craniosynostosis, with the symptoms and head shape varying according to the affected suture. Symptoms & Signs Abnormally shaped or uneven head A ridge along the affected skull suture Narrow, elongated, or asymmetrical head shape Changes in facial or forehead appearance Slow head growth in some cases Developmental or neurological concerns in more complex cases Diagnosis & Treatment Early evaluation by a pediatrician, pediatric neurosurgeon, or craniofacial specialist is important. Diagnosis may involve physical examination and, when required, imaging studies. Treatment depends on the child’s age, the type and severity of craniosynostosis, and whether one or multiple sutures are involved. Surgical treatment may be recommended to correct the skull shape and provide adequate space for brain growth.
