“…Additionally, the morphological variations that we found in the skulls of the collection (here reported as occasional findings) are consistent with the literature, which supports the notion that said anatomic variants are rather common (Collipal et al, 2009;Aviles-Solis et al;Rodrigues et al;Singh et al;Raval et al).…”

SUMMARY:Among osteological anatomic variations are those of the skull base foramina. These openings have conventionally been classified as either constant or variant. Their presence and dimensions have been associated with certain pathologies and procedural complications. Additionally, variability in these foramina between different ethnic groups has been observed, and it is sometimes possible to identify particular patterns of variability in certain populations. This anthropometric cross-sectional study seeks to determine the principal dimensions (bilateral anteroposterior and lateromedial diameters) of five constant skull base foramina in the adult Muisca population of the Tibanica anthropological collection at Universidad de los Andes. The studied foramina were magnum, jugular, ovale, spinosum, and external opening of the carotid canal. Only dimensions of the external openings of the foramina were recorded, owing to the preservation state of the skulls in the collection. The mean left and right anteroposterior and lateromedial diameters were 3.48 mm, 6.16 mm and 3.25 mm, 6.26 mm for the foramen ovale; 2.38 mm, 2.65 mm and 2.39 mm, 2.66 mm for foramen spinosum; 8.36 mm, 15.41 mm and 8.55 mm, 15.10 mm for the jugular foramen; 5.28 mm, 6.75 mm and 5.48 mm, 6.97 mm for the external opening of the carotid canal; and 33.90 mm, 29.47 mm for the foramen magnum. All foramina were measured twice, no important differences were observed between the results obtained in the first and second measurements. The skull base foramina of the sample studied did not suggest high variability within the population regarding these characteristics. Moreover, we can state that the morphometric profile displayed by the Tibanica collection at Universidad de los Andes is different from the one observed in other populations. Additional studies of anatomic variations in indigenous populations may be needed to make possible similarities and/or differences and their causes evident.

Normal craniovascular variation in two modern European adult populations

The vascular networks running into the meningeal layers, between the brain and braincase, leave imprints on the endocranial surface. These traces are visible in osteological specimens and skeletal collections, providing indirect evidence of vascular patterns in those cases in which bone remains are the only source of anatomical information, such as in forensic science, bioarchaeology and paleontology. The main vascular elements are associated with the middle meningeal artery, the venous sinuses of the dura mater, and the emissary veins. Most of these vascular systems have been hypothesized to be involved in endocranial thermal regulation. Although these traits deal with macroanatomical features, much information on their variation is still lacking.In this survey, we analyze a set of craniovascular imprints in two European dry skull samples with different neurocranial proportions: a brachycephalic Czech sample (n = 103) and a mesocephalic Italian sample (n = 152). We analyzed variation and distribution, correlation with cranial metrics, and sex differences in the dominance of the branches of the middle meningeal artery, the patterns of confluence of the sinuses, and the size of the emissary foramina. The descriptive statistics provide a reference to compare specimens and samples from different case studies. When compared with the Italian skulls, the Czech skulls display a greater dominance of the anterior branch of the middle meningeal artery and more asymmetric right-dominance of the confluence of the venous sinuses. There is no sex difference in the middle meningeal vessels, but males show a greater prevalence of the occipito-marginal draining system. Differences in the middle meningeal vessels or venous sinuses are apparently not influenced by cranial dimensions or proportions. The mastoid foramina are larger in larger and more brachycephalic skulls, which increases the emissary potential flow in the Czech sample and males, when compared with the Italian samples and females, respectively. The number of mastoid foramina increases in wider skulls. This anatomic information is necessary to develop further morphological and functional inferences on the relationships between neurocranial bones and vessels at the genetic, ontogenetic, and phylogenetic levels.

Morphol., 34(4):1328Morphol., 34(4): -1332Morphol., 34(4): , 2016. SUMMARY:The foramen venosum (FV) is an anatomical structure situated at the base of the skull, generally posteromedial to the foramen rotundum and anteromedial to the foramen ovale. Its prevalence and patency may be related to the shape of the skull. The objective of this study was to verify the prevalence and patency of the FV and its association with the different skull types. Overall, 143 dry skulls were screened. Of these, 84 were considered to be in an adequate state of conservation and were included in the analysis, which was conducted through a cross-sectional view of the skullcap. The transverse (T) and anteroposterior (AP) diameters of the skull were evaluated by pachymetry and the skull type was classified according to the cephalic index (CI) (CI = T/ AP x 100). The presence and patency of the FV were evaluated. Overall, 25 % of the skulls were dolichocephalic, 21.4 % subdolichocephalic, 26.2 % mesaticephalic, 16.7 % sub-brachycephalic and 10.7 % brachycephalic. Overall, the FV was found in 41.6 % of the skulls (n=35), with this prevalence being greater in the mesaticephalic skulls (50 %; n=11). Patency was 25 % (n=21). A positive correlation was found between the CI and the presence of the FV in dolichocephalic skulls (on the right-hand side only) and in sub-brachycephalic skulls (bilaterally). In conclusion, the prevalence of the FV was considerable in the sample analyzed and was directly associated with the CI in dolichocephalic and sub-brachycephalic skulls.
