The difference is that this time, the deformity mostly shows at the occiput.By Virchows law, restriction of growth will occur at the ipsilateral side of the head; compensatory growth will occur at the contralateral side of the head. This growth pattern exerts an effect at the base of the skull, which is not even when the child is assessed from a point of view standing behind the child, as well as on the cervical spine, which shows a curvature. In addition, from a point of view standing behind the child, a bulging of the mastoid can be seen. Minimal forehead asymmetries are typically seen. Brachycephaly
Brachycephaly, or a short head, is the result of a closure of both the coronal sutures. Following Virchows law, this will result in a childs head with a restriction of growth in the forward direction and in the backward direction: recessed frontal bones and a flattened occiput. Compensatory growth will occur sideways, due to the sagittal suture, and upwards, due to the lambdoid sutures. Oxycephaly
Oxycephaly, also known as turricephaly and high-head syndrome, is a type of cephalic disorder. This is a term  sometimes used to describe the premature closure  of the coronal suture plus any other suture, like the lambdoid suture,

Pansynostosis
The word pansynostosis is also Greek-derived and can be translated as "all one bone", indicating that all of the sutures are closed. In general practice, the term is used to describe the children with three or more cranial sutures closed.Pansynostosis can present in several ways.
An increase in growth at the metopic and the sagittal suture accounts for the parallel plane and will result in bulging at the temporal fossa. Compensatory growth in the perpendicular plane occurs on the side of the head with the patent coronal suture, the contralateral side. Half of the forehead will bulge forwards. Assessment of the skull from a top view shows asymmetry of the frontal bones, an increased width of the skull and a forward displacement of the ear at the ipsilateral side of the head. Assessment of the skull from a frontal view will show asymmetrical features of the face, including a displacement of the chin point of the jaw and a deviation of the tip of the nose. The chin point is located more to the contralateral side of the head, due to the ipsilateral forward displacement of the temporomandibular joint together with the ear. The tip of the nose will also point towards the contralateral side. Complications based on the skull deformation include malocclusion of the jaw, in as many as 90%; a subtle form of strabismus, caused by the asymmetrical placement of the orbits; and refractive error, particularly astigmatism, due to asymmetrical development of the orbits. Posterior plagiocephaly
Unilateral lambdoid synostosis is also called posterior plagiocephaly, indicating that this gives, just like unilateral coronal synostosis, a skew head.
