Brachycephaly (from Greek meaning “short” and “head” is the shape of a skull shorter than typical for its species. It is perceived as a desirable trait in animals but in humans  the cephalic disorder is known as flat head syndrome, and results from premature fusion of the coronal sutures (read craniosynostosis) or from external deformation (read plagiocephaly). The coronal suture is the fibrous joint that unites the frontal bone with the two parietal bones of the skull. The parietal bones form the top and sides of the skull.kisa-genis-kafa
