Histomorphometry of parietal bones versus age and race.
In order to assure optimal harvesting and safest surgical procedures, the donor site should be located in the thicker areas of the parietal bone.
The purpose of the present study was to determine the thickness of the parietal bone as well its relation with sex and cephalic index in the attempt to improve guidance for harvesting of calvarial bone graft material.
The midline and parietal bones are slightly visible in this image.
The BPD is measured at the widest diameter of the head-from the leading edge of the parietal bone to the leading edge on the opposite side.
Clinical and radiological features include a large brachycephalic head, small and angular face, prominent frontal and parietal bones
and drooping shoulders with excessive mobility.
We have also to consider that from birth to the ninth month of age, the baby's parietal bones normally have the most active growth period and the more accentuated bending, producing even a bilobal appearance in adults.
Asymmetrically distributed on both sides of the fontanel, the lesion also extended back some millimeters over the coronal suture, onto the right parietal bone (the left parietal, almost completely destroyed, could not be examined).
5, 6] This indicates that the bone developing from middle and upper pairs of nuclei was part of parietal bone
in early mammalian phylogeny and it has now come to join the occipital bone in primates and man.
In the extra-oral physical examination we could notice short height, reduced inter acromial distance, proeminet frontal and parietal bones
, determining an increase in the cranial perimeter (Fig.
Fig 3 shows that the sphenoparietal type is a sutural pattern in which the sphenoid and parietal bones are in direct contact, preventing the frontal and temporal bones making contact with one another.
Fig 4 shows that frontotemporal type is a sutural pattern in which the frontal and temporal bones are in direct contact, preventing the sphenoid and parietal bones making contact with one another.
