Effets de la déformation artificielle sur les structures internes du crâne et l’articulation temporo-mandibulaire

Abstract : Artificial cranial deformation (ACD) is a very ancient and widespread cultural practice (Dingwall, 1931). The study of ACDs provides informations on the reactions of the different craniofacial modules to exterior pressure, and on the ontogenic interactions between these modules. The question of the effect of ACD on the skull base, especially on the basicranial angle, is not solved and the effects of ACD on the temporomandibular joint have not been thoroughly studied. The aim of this master’s thesis is to explore based on a small series of non-deformed and deformed skulls including anteroposterior and circumferential Bolivian and “toulousain” type French deformed skulls, the effect of different types of ACD on the base, especially the basicranial flexion, and on the masticatory system, particularly the location of the mandibular fossa, by applying a three-dimensional geometric morphometric approach to tomographic data. Our results confirm that ACD affects the basicranial shape and indicate that the masticatory system is also affected, via the temporomandibular joint. Our results suggest also differential effects of different types of ACDs on the craniofacial modules.
