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 ...
Artificial cranial deformation or modification, head flattening, or head binding is a form of body alteration in which the skull of a human being is deformed intentionally. It is done by distorting the normal growth of a child's skull by applying pressure.
Trigonocephaly is a congenital condition due to premature fusion of the metopic suture (from Ancient Greek metopon 'forehead'), leading to a triangular forehead. The premature merging of the two frontal bones leads to transverse growth restriction and parallel growth expansion.
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.
The distinctive head shape seen in kleeblattschaedel is caused by the closure of the sagittal, coronal, and lambdoid sutures, with subsequent bulging of the cranial contents leading to a trilobate head shape. [7] The condition is also caused by absence of the coronal and lambdoid sutures. [10] Conditions with kleeblattschaedel include: [11] [12]
Noonan syndrome (NS) is a genetic disorder that may present with mildly unusual facial features, short height, congenital heart disease, bleeding problems, and skeletal malformations. [1] Facial features include widely spaced eyes , light-colored eyes, low-set ears , a short neck, and a small lower jaw . [ 1 ]
[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]
Turricephaly is a type of cephalic disorder where the head appears tall with a small length and width. [3] [4] It is due to premature closure of the coronal suture plus any other suture, like the lambdoid, [5] or it may be used to describe the premature fusion of all sutures. [2] It should be differentiated from Crouzon syndrome.
