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.
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.
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.
Brachycephaly (derived from the Ancient Greek βραχύς, 'short' and κεφαλή, 'head') is the shape of a skull shorter than average in its species. It is perceived as a cosmetically desirable trait in some domesticated dog and cat breeds , notably the pug and Persian , and can be normal or abnormal in other animal species.
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 ...
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.
Elderly woman with craniofacial signs of Saethre-Chotzen syndrome. Flat, asymmetric head and face [3] Head is typically cone-shaped (acrocephaly) or flat (brachycephaly) but can also be long and narrow (dolichocephaly) [4] Head is short from front to back [5] Lopsided face [4] Low-set hairline causing forehead to appear tall and wide [5]
Within any given patient, a variety of symptoms can occur, and the impairment of ability is not only binary but can range in severity. For example, Patient SM is a prosopagnosic with a unilateral lesion to left extrastriate cortex due to an accident in his twenties who displays behavior similar to congenital prosopagnosia . [ 5 ]
