“…The DVS results indicate that the asymmetric patterns (type B and C) were common. The SSS communication, either with the right or left TS, might be influenced by the asymmetric development of the occipital lobes due to ACM (Boman et al, 2016; Natahi et al, 2019). The SSS traces were light at the CS, and both the TS and SS were marked.…”

“…The ethnohistorical record (Dingwall, 1931) and recent research mention the potential health risk involved in ACM (Lekovic, Baker, Lekovic, & Preul, 2007; Mendonça de Souza, Reinhard, & Lessa, 2008). Side effects, like secondary cranial asymmetry, circulatory problems, necrosis, and infections, could result from the mechanical pressure exerted during the head shaping, the lack of hygiene, blood, and air circulation (Boman, Froment, & Charlier, 2016; Torres‐Rouf, 2020).…”

The impressions left by the vascular system on the surface of the skull, like those of the middle meningeal vessels, the dural venous sinuses, and the emissary veins, are a unique source of vascular and anatomical evidence when working with osteological collections, as is the case with bioarchaeological, forensic, and paleoanthropological investigations. Craniovascular features have been investigated in multiple modern human populations; however, no information is available on their analysis in artificially modified pre‐Hispanic Caribbean skulls. To shed light on this matter, this report provides a reference for the prevalence, characterization, and distribution of craniovascular traits using a collection of fronto‐occipital tabular oblique artificially shaped pre‐Columbian crania from Cuba (the largest archipelago in the Caribbean) as a case study. Results suggest that changes produced by intentional head‐shaping may have affected the pattern and direction of endocranial vascular structures, whereas emissary foramina placed in less‐affected areas appear to be less influenced by changes in cranial morphology. Future work will investigate the consequences of artificial modification on the cranial and endocranial vascular systems and compare them with unmodified pre‐Columbian specimens. Also, the effects of head shaping in endocranial thermoregulation should be explored in the future. Providing new knowledge about the prevalence and variation of the craniovascular traits may be useful not only in research based on osteoarcheological collections but also in medicine.

“…More precisely, it has recently been established that external constraints exerted on the skull vault modify the three-dimensional morphology of the orbits and the maxillary sinuses (Khonsari et al 2013a). I has also been shown that the thickness of skull vault bones are modified in the zones where pressure is exerted by the deformation devices (Grupe, 1984;Khonsari et al 2013a;Boman et al 2016).…”

Zygomatic bone shape in intentional cranial deformations: a model for the study of the interactions between skull growth and facial morphology

et al. 2016

Intentional cranial deformations (ICD) were obtained by exerting external mechanical constraints on the skull vault during the first years of life to permanently modify head shape. The repercussions of ICD on the face are not well described in the midfacial region. Here we assessed the shape of the zygomatic bone in different types of ICDs. We considered 14 non-deformed skulls, 19 skulls with antero-posterior deformation, nine skulls with circumferential deformation and seven skulls with Toulouse deformation. The shape of the zygomatic bone was assessed using a statistical shape model after mesh registration. Euclidian distances between mean models and Mahalanobis distances after canonical variate analysis were computed. Classification accuracy was computed using a cross-validation approach. Different ICDs cause specific zygomatic shape modifications corresponding to different degrees of retrusion but the shape of the zygomatic bone alone is not a sufficient parameter for classifying populations into ICD groups defined by deformation types. We illustrate the fact that external mechanical constraints on the skull vault influence midfacial growth. ICDs are a model for the study of the influence of epigenetic factors on craniofacial growth and can help to understand the facial effects of congenital skull malformations such as single or multi-suture synostoses, or of external orthopedic devices such as helmets used to correct deformational plagiocephaly.
