closure in placental mammals: Phylogenetic patterns, intraspecific variation, and comparison with marsupials.
Moreover, it had two advantages: first, the coordinate system could be defined easily during the operation because the scalp covering the zygomatic arch, FPZ, SMC, and the mastoid is thin enough to palpate points A, B, and C; second, this positioning system does not need recognition of the cranial sutures
(the lambdoidal, squamosal, and parietomastoid sutures) which should be identified for using the traditional method to locate the IMTS.[sup]
(1), (2) Cleidocranial dysostosis presents similarly to pycnodysostosis, with persistent open fontanelles and cranial sutures
; however, it always involves the clavicle (a bone only rarely affected in pycnodysostosis) (1) and does not result in overall increased bone density.
compile 19 chapters examining the phenomenon of the fusion of the cranial sutures
of an infant's skull.
The cranial sutures
are open and normal, therefore conservative management, such as physiotherapy and helmet therapy, is frequently used to treat this condition.
Differential diagnosis should be made to exclude craniosyntosis, which is a more serious condition involving premature fusion of one or more of the cranial sutures
. (2) Craniosyntosis usually requires surgical intervention to prevent more serious deformity and possible brain damage.
The cranial sutures
are a physiological mechanism designed to accommodate or adapt to the existing anatomical make-up, with or without an imposed strain or restriction being present.
Craniosynostosis, or premature closure of the cranial sutures
, occurs in 1:2,100 children (Lajeunie et al., 1995; see Fig.
In its classic form, patients experience a premature closure of the cranial sutures
, which leads to brachycephaly, proptosis, a small maxilla, and anomalies of the external and middle ear.
He said that cranial sutures
only calcify before death under pathological circumstances.
