OBJECTIVES Although referrals for nonsynostotic plagiocephaly (NSP) have increased in recent years, the prevalence, natural history, and determinants of the condition have been unclear. The objective of this study was to assess the prevalence and natural history of NSP in normal infants in the first 2 years of life and to identify factors that may contribute to the development of NSP. METHODS...

Asymmetry of the cranium noted in which the cranium is growing superiorly and laterally on the left side of the patient's head due to a fused right lambdoid suture. Figure 2. Preoperative photograph showing a superior view demonstrating asymmetrical cranial growth of the left side of the patient's head due to a fused lambdoid suture on the right.

BACKGROUND Unilateral coronal synostosis (UCS) often causes notable facial twist in affected patients. This condition occurs when the midface deviates toward the synostotic side, and the lower face deviates away from the synostotic side. The exact underlying mechanism for this phenomenon remains unclear. It has been proposed that premature fusion of facial sutures may play a role in the formati...

part being disturbed at the expense of another to the ultimate perfecting of the organism, that is to say, towards maturity, in other words, until the individual is capable of reproducing the species. Development, though a continuous process, naturally divides itself into intrauterine and extrauterine stages, a clinically useful division spoken of obstetrically as antenatal and postnatal. Each ...

We present a syndrome manifested in two half brothers and their two maternal aunts which is characterised in the two boys by severe mental retardation and craniofacial dysmorphism (broad, coarse features and marked plagiocephaly with flattened occiput), and in the aunts merely by moderate mental retardation without dysmorphic features. The brothers do not seem to fall into any previously descri...
