“…Over the years a number of researchers have reported the incidence and distribution of wormian bones in the skulls of different geographical population groups, and there are significant differences in the observations documented (Saxena et al 1986;Murlimanju et al 2011;Khan et al 2011;Marti et al 2013;Cirpan et al 2015). This prevalence of racial variations in the morphology of wormian bones can be explained in accordance with the theory put forward by some authors that occurrence of wormian bones is determined by genetic factors (El-Najjar et al 1985;Opperman 2000).…”

“…However, as ''cultural cranial deformation'' is usually associated with 'plagiocephaly', i.e. asymmetry due to pressure exerted on infant skull (Marti et al 2013), and, as we observed, the existence of notable symmetry in terms of wormian bones in our skulls samples, this might be considered as evidence of the absence of practices related to cranial deformation in Eastern India. Regarding all the parameters evaluated in the present study in relation to morphology of the wormian bones, considerable variations (statistically significant in most cases) were observed, with values reported from studies conducted on skulls from other regions of India as well as different parts of the world.…”

“…Researchers have opined that wormian bones can be found in healthy individuals as a normal variant; however, they tend to be less numerous than when associated with pathological conditions like skeletal dysplasias (Marti et al 2013). Notably, most authors have opined that the presence of multiple wormian bones is not always pathognomonic (Vishali et al 2014).…”

“…Wormian bones are often considered to be present as simple anatomical variants; nevertheless, they can be associated with certain bony dysplasias like cleidocranial dysostosis, pycnodysostosis, congenital hypothyroidism, rickets and most commonly osteogenesis imperfecta (Marti et al 2013). However, when wormian bones occur as normal variants, they tend to be smaller in size and less in number than when they are associated with skeletal dysplasias (Kaplan et al 1991).…”

“…He referred to a bony ossicle located in the posterior fontanelle as the 'ossiculum antiepilepticum' as sutural bones were believed to have antiepileptic virtues in those days. After him, this particular sutural bone is nowadays referred to as the 'Paracelsian ossicle' (Marti et al 2013). However, it was the Danish anatomist, Ole Worm (1588-1654), who was first to make a detailed description of accessory or supernumerary bones present within the cranial sutures and fontanelle, in a letter addressed to the famous anatomist, Thomas Bartholin (1616Bartholin ( -1680.…”

An anatomical study of wormian bones from the eastern part of India: is genetic influence a primary determinant of their morphogenesis?

Over the years a number of investigators have analysed the morphology of wormian bones in different population groups across the world. There have been significant variations between findings reported in these studies, and this has prompted researchers to focus on the influence of genetic factors on the morphology of these bones. In the light of the above observation, we considered it justified to conduct anatomical studies on wormian bones in different population groups; hence, we undertook the present study to look into the morphological details of these bones among a population in the eastern part of India. We observed a total of 120 adult dry human skulls of unknown age and sex, and noted the anatomical details of wormian bones when present. It was observed that wormian bones were present in 45 % of skulls, and that 30 % of skulls had more than one wormian bone. We also found that 2.5 % of the skulls had ten or more wormian bones, which is considered as pathognomonic. Maximum incidence (53.33 %) was observed at the lambdoid suture and minimum incidence at the bregma and metopic suture (0.61 % in each case). We noted a high incidence (21.21 %) of Inca bone/lambdoid ossicle, and bilaterally symmetrical wormian bones were present in 12.5 % study skulls. There were statistically significant (P < 0.05) variations between the findings of the present study and values reported in previous studies conducted in other regions of India and different parts of the world. Our observations favour the view that genetic influence primarily determines the morphology of wormian bones.
