Facial reconstruction of a pathological case.

In this paper, we describe a forensic paleopathology case using findings obtained from images of a skull with leontiasis ossea. This unique specimen is on display in the National Museum of Anthropology and History in Mexico. The skull shows tissue overgrowth, periosteal bone proliferation, which produced a cortical and diploid thickening involving the entire bone matrix. The study of images, X-rays, and helical computed tomography revealed generalized hyperostosis obliterating the maxillary and sphenoid sinuses, and two exuberant bony masses arising from the maxilla with encroachment of the anterior nasal opening. In order to reconstruct an image of the external appearance in life, a copy was obtained in the first place, using a stereolithography machine, after that, three-dimensional (3-D) facial reconstruction technique was applied, thus an approximation of the external appearance of this specimen was obtained. During the process, we encountered several difficulties, mainly when interpreting the cortical topography, the position of eyes and mouth. In this sense, facial reconstruction allows only for a moderate investigation due to the limited information that can be obtained from the skull and the significant alterations observed.
