Plagiocephaly, also known as flat head syndrome, [1] [2] is a condition characterized by an asymmetrical distortion (flattening of one side) of the skull.A mild and widespread form is characterized by a flat spot on the back or one side of the head caused by remaining in a supine position for prolonged periods.
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 children have nearly 50% chance of developing this condition. [5] A theory regarding the involvement of OSA as a causative agent for elevated intracranial pressure suggests an association with the auto-regulation of blood flow in the brain. [33] Certain cells in the brain respond specifically to an increase of CO 2 in the blood.
Craniofacial surgery is a surgical subspecialty that deals with congenital and acquired deformities of the head, skull, face, neck, jaws and associated structures. Although craniofacial treatment often involves manipulation of bone, craniofacial surgery is not tissue-specific; craniofacial surgeons deal with bone, skin, nerve, muscle, teeth, and other related anatomy.
Brachycephaly is the common pattern of growth, where the coronal sutures close prematurely, preventing the skull from expanding frontward or backward and causing the brain to expand the skull to the sides and upwards. This results in another common characteristic, a high, prominent forehead with a flat back of the skull.
Antley–Bixler syndrome presents itself at birth or prenatally. [2] Features of the disorder include brachycephaly (flat forehead), craniosynostosis (complete skull-joint closure) of both coronal and lambdoid sutures, facial hypoplasia (underdevelopment); bowed ulna (forearm bone) and femur (thigh bone), synostosis of the radius (forearm bone), humerus (upper arm bone) and trapezoid (hand ...
McGillivray syndrome is a birth defect in which one or more of the joints between the bones of the baby's skull close prematurely, before the baby's brain is fully formed. When the baby has craniosynostosis, the brain cannot grow in its natural shape and the head is misshapen. It can affect one or more of the joints in the baby's skull. In some ...
The first was in 1973, on an infant who died shortly after birth. [90] The examination revealed extensive brain damage, including microcephaly, migration anomalies, corpus callosum dysgenesis, and a massive neuroglial, leptomeningeal heterotopia covering the left hemisphere. [91] In 1977, Clarren described a second infant whose mother was a ...
