Cranial abnormalities refer to irregularities in the shape or structure of the skull. These can occur due to genetic factors, environmental influences, or developmental issues during pregnancy. Common types include craniosynostosis, where skull sutures fuse too early, and plagiocephaly, characterized by an asymmetrical head shape. Diagnosis typically involves physical examination and imaging techniques like CT scans or MRI. Treatment options vary based on the type and severity of the abnormality, ranging from observation to surgical intervention. Early detection is crucial for optimal outcomes, as it can help prevent complications related to brain development and function.
