CASADO MENDEZ, Pedro Rafael et al. Frequency of the wormian bones in Manzanillo autochthonous population. Rev.Med.Electrón. [online]. 2016, vol.38, n.1, pp. 24-35. ISSN 1684-1824.

Background: suture or wormian crania bones are supernumerary, accessorial and inconstant bone structures. The aim of this research was determining the presence, number and location of worm bones in Manzanillo autochthonous population. Materials and Methods:  a quantitative, longitudinal, prospective, observational and descriptive study was carried out in 93 crania in good status of conservation, coming from corpses exhumed in the cemetery of Manzanillo, Granma. Crania belonged to dead people who were born in Manzanillo, and anthropologic measures were done on them. Outcomes: wormian bones were found in 44.09 % of the studied crania. 62.5 % of the 72 wormian bones belonged to female crania. 56.9 % of these bones were located in the left side. Both, mesocephalic and hyperbrachycephalic crania showed the presence of these bones (31 crania) but the number of bones was bigger in hyperbrachycephalic crania (33 bones). Conclusions: the wormian bones are bone formations appearing in less than half of the autochthonous population of Manzanillo, having more incidences in women, in the left side of the body and in hyperbrachycephalic crania. The lambdoid bone was the most frequent one.
