Plagiocephaly is a diagonal asymmetry across the head shape. Often it is a flattening which is to one side at the back of the head and there is often some facial asymmetry. Depending on whether synostosis is involved, plagiocephaly divides into two groups: synostotic, with one or more fused cranial sutures, and non-synostotic (deformational).
[10] [11] The resulting shape appears triangular from above. [12] Like many medical terms, 'trigonocephaly' is derived from Greek, and indicates the head in question is triangular in shape. A facial feature of metopic synostosis is hypotelorism; in the frontal view, it can be seen that the width between the eyes is smaller than usual. [11]
Cranial sutures. A defining characteristic of Crouzon syndrome is craniosynostosis, which results in an abnormal head shape.This is present in combinations of: frontal bossing, trigonocephaly (fusion of the metopic suture), brachycephaly (fusion of the coronal suture), dolichocephaly (fusion of the sagittal suture), plagiocephaly (unilateral premature closure of lambdoid and coronal sutures ...
The treatment of Muenke syndrome is focused on the correction of the abnormal skull shape and mirrors the treatment of coronal craniosynostosis. The abnormal growth patterns continue throughout the growing years; therefore, intervention, accurate diagnosis, and a customized, expertly carried-out treatment plan should be a primary concern.
Scaphocephaly or sagittal craniosynostosis is a type of cephalic disorder which occurs when there is a premature fusion of the sagittal suture.Premature closure results in limited lateral expansion of the skull, resulting in a characteristic long, narrow head. [1]
The TWIST gene in mice, functions in the development of the muscle and skeleton of the face, head, hands, and feet. Mice that were lacking both copies of the TWIST gene were spontaneously aborted prior to birth, and had serious deformities including abnormal limb and head defects and failure of the neural tube to properly close. However, mice ...
Macrocephaly is a condition in which circumference of the human head is abnormally large. [1] It may be pathological or harmless, and can be a familial genetic characteristic. . People diagnosed with macrocephaly will receive further medical tests to determine whether the syndrome is accompanied by particular disorde
Babies' mobile cranial bones form a cone shape as they pass through the birth canal and soon thereafter return to a normal shape; however, a baby affected by carpenter syndrome maintains a cone shaped head. [citation needed] A baby affected by Carpenter syndrome will also display malformations of the face.
