Due to its dense cortical layer, the calvarium
has proven to be a source of mechanically reliable bone grafts, which also show very limited resorption over the years (Smith & Abramson; Le Lorch-Bukiet et al., 2005).
Diffuse osteopenia, prominent vascular markings in skull, thin and large calvarium
with shallow diploic space, multiple wormian bones, small mandible with infantile obtuse angle and short ascending rami, hypoplastic facial bones, open cranial fontanelles, thin short clavicles, dwarfism, abnormally gracile ribs involving the posterior segments of the upper ribs, slender long bones, kyphosis, coxa valga, and progressive acroosteolysis of the terminal phalanges were the major roentgen findings previously reported.
None of these cases was reported with changes in thoracic skeleton, scoliosis, pelvis or calvarium
The osseointegration book: From calvarium
Well-described donor sites for bony and cartilaginous framework repairs are the ears, ribs, and/or calvarium
. Numerous techniques and donor sites have been described for nasal lining reconstruction, especially local flaps based on the nasal septal mucosa, inferior turbinates, or other areas of nasal lining.

To make an injection, orient the needle perpendicular to the skull and press through the calvarium
to approximately 2 mm depth.
Initial imaging with Computed Tomography (CT) revealed a large soft tissue mass appearing to arise from the calvarium
with minimal moderate extrinsic mass effect on the adjacent brain, (Figure 1) while Magnetic Resonance Imaging (MR) revealed a 4.6 x 4.1 cm mass (Figure 2), suggesting a lesion arising from the calvarium
or an extra-axial mass, such as a meningioma.
Rats with defects in the calvarium
filled with coagulum and sacrificed after 7 days (control group) (n = 5);
Although bone is the second hardest substance in the human body, it is extremely pliable when subjected to even the smallest forces, esp over prolonged periods of time (as exemplified by the grooving of the inner surface of the calvarium
, by small arterioles and venules).
After sacrifice of the rat, the calvarium
(frontal and parietal bone) was taken immediately and all adhering soft tissues were removed.
