acquired plagiocephaly due to prolonged pressure on one part of the skull.


(pla?je-o-sef'a-le) [ plagio- + -cephaly]
A malformation of the skull producing the appearance of a twisted and lopsided head, caused by irregular closure of the cranial sutures.

deformational plagiocephaly

Plagiocephaly on one side the skull of an infant, usually after repeatedly sleeping in a single position, e.g. on the infant's back, to prevent SIDS.

It can usually be treated nonoperatively by repositioning the developing infant frequently, or by having the child wear a protective, adjustable helmet while resting.

While treatment for positional plagiocephaly exists, it is costly.
A multidisciplinary task force complied of clinical experts was assigned to perform a comprehensive review and analysis of the research on diagnosis and treatment of positional plagiocephaly. Developed by the Congress of Neurological Surgeons, these guidelines are also endorsed by the Joint Guidelines Committee of the American Association of Neurological Surgeons and the Congress of Neurological Surgeons, and the American Academy of Pediatrics.
In most cases, positional plagiocephaly can be diagnosed by clinical examination.
Present in up to 30% of infants, usually within the first 4 months of life, positional plagiocephaly presents in a way that is unique and distinguishable from deformities caused by early suture fusion.
Although some researchers suggest that this problem may contribute to developmental delays, it's just as likely that the developmental delays may cause the positional plagiocephaly. Children with developmental delays, especially in motor function, may move less, thus causing the skull-shape changes.

Since the recommendation in the early 1990s to place infants on their backs in order to reduce the risk of sudden infant death syndrome, there has been an increase in the incidence of positional plagiocephaly (a right- or left-sided occipital flattening) as indicated by referrals to paediatricians, neurosurgeons and craniofacial surgeons for advice and management.
It may be found that torticollis has aggravated potential positional plagiocephaly by preventing the head from turning 180[degrees].
