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.
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.
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]
[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]
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 problem is often found in conjunction with hydrocephalus, which is a condition in which too much fluid is found within and around the brain, placing pressure on the brain and surrounding tissues. Often the head will appear dome-shaped, and the open fontanelle is noticeable as a "soft spot" on the top of the dog's head.
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).
This affects the shape of the head and face, resulting in a cone-shaped head and an asymmetrical face. Individuals with SCS also have droopy eyelids ( ptosis ), widely spaced eyes ( hypertelorism ), and minor abnormalities of the hands and feet ( syndactyly ). [ 2 ]
