“…With regard to the skull, the various cranial bones exhibit complex shapes and variations in thickness throughout. Whilst some areas of the cranium can measure <3mm thickness [42], other areas are much thicker functioning as 'buttresses' (Figure 6) to strengthen particular areas [32]. These variations influence the course of fractures which will follow the line of least resistance and so deviate toward areas where the bone is thinner.…”

“…Nonetheless, harvesting in thicker areas makes neurosurgical complications less likely to occur (Markowitz;Frodel et al;Hwang et al, 2000;Jung et al, 2003;de Souza Fernandes et al).…”

“…The calvarium has been used worldwide as autogenous bone grafts donor bone in maxillofacial reconstruction (Smith & Abramson, 1974;Zins & Whitaker;Donovan et al, 1993), in reconstruction of the alveolar process in both the maxilla and mandible, as well as in procedures involving osseointegrated dental implants (Vermeeren et al;Smolka et al, 2006;de Souza Fernandes et al, 2011).…”

“…Another feature of calvarial bone is that it contains higher levels of bone growth factors and earlier revascularization resulting in improved keeping of shape and volume of the material transplanted, besides showing improved healing of the donor site as compared with bone of endocondral origin. Moreover, the donor site is significantly nearer from the reconstruction site (Zins & Whitaker; Kulali & Kayaalp, 1991;Markowitz, 1992;Ozaki & Buchman;Le Lorch-Bukiet et al;de Souza Fernandes et al).…”

“…Grafts from the parietal area provide bone of the appropriate shape for most facial applications, thus making the parietal the bone of choice to harvest bone graft material. Because of the thickness of the cortical layers of this calvarial bone, graft material can be harvested from the external cortex leaving the structures inside the cranial cavity intact (Pensler & McCarthy, 1985;Cannella & Hopkins, 1990;Frodel et al, 1993;Hwang et al, 2000;Smolka et al;de Souza Fernandes et al).…”

M. Potential donor sites of the parietal for bone grafting and its relationship to the cephalic index. Int. J. Morphol., 35(3):986-991, 2017. SUMMARY:The purpose of the present study was to chart the thickness of the parietal bone and establish its relationship with the cephalic index and sex aiming at improving current knowledge and guidance for obtaining calvarial bone auto-graft material. Both left and right parietal bones of 150 skulls of adult human cadavers classified as either dolicho-, meso-, or brachicephalic, and as either male or female had their thickness measured at 3 levels -superior (S), middle (M) and inferior (I) -and at 3 points -anterior (a), middle (m) and posterior (p) -in each level, all evenly laid out. No relevant differences in thickness whether comparing sex or cephalic index was evidenced. The thickest measurements were found at points located at superior and middle levels in middle and posterior positioning -Sm, Sp, Mm and Mp -with median values ranging from about 5.5mm to 7.13mm. At inferior level and posterior positioning, thickness median values ranged from 4.71 to 5.84mm. Safer harvesting of bone graft material occurs in Sm, Sp, Mm and Mp areas of the parietal bone. Only exceptionally should Ip domain be used, whereas Sa, Ia and Im regions should be considered non-donor sites.
