What is the most common form of craniosynostosis that occurs due to early fusion of the suture in the midline of the skull?

The most common form of craniosynostosis that occurs due to the early fusion of the sutures in the midline of the skull is sagittal craniosynostosis. This condition results from the premature closure of the sagittal suture, which runs from the front to the back of the skull, dividing it into left and right hemispheres. When this suture fuses too early, it restricts the natural growth of the skull in the area along the suture line. Consequently, the skull tends to grow longer and narrower, leading to a characteristic shape often referred to as "scaphocephaly."

This condition is significant because it can lead to various complications, including increased intracranial pressure and developmental delays, if not diagnosed and treated promptly. Understanding that sagittal craniosynostosis is the most common type emphasizes the importance of monitoring head shape and growth patterns in newborns, as earlier detection and intervention can lead to better outcomes for affected infants.
