“…On the other hand, WBs most commonly located is the LS, among different populations. In the present study, WBs most commonly appear in the LS (44.6%), similarly to Edwards and co-authors' study [10]. Murlimanju et al [23,24] reported that WBs are found along the LS in 56.4%.…”

“…Other frequent localizations are coronal suture, bregma, lambda, pterion, and asterion. However, WB may, although rarely, occur in the sutures connecting the craniofacial bones -for example in the frontonasal suture (Edwards et al 2017) or in the orbital cavity between the frontal, lacrimal and ethmoid bone (Rizvi et al 2018). The anatomical denomination of Wormian bones is still debated (Romero-Reverón 2020) while the etiology of sutural bone formation still remains unclear.…”

Wormian bones (WB) are the irregular bone structures developed from additional centers of ossification. Although they are commonly found in healthy individuals, under certain conditions (number >10, mosaic pattern, large size), they can indicate pathology. While their coexistence with numerous diseases is well-documented, and various studies have reported their prevalence in populations of various geographic regions, no qualitative critical review of such studies has been conducted. The aim of this paper is to perform a critical review of research studies on the presence of Wormian bones in populations worldwide, with a particular emphasis on the methodology used and the selection of the samples studied. A sample of 44 original research articles was selected via PubMed and Google Scholar databases. Four criteria were assessed: 1) number of individuals in each group, 2) known sex of individuals, 3) selection criteria of individuals, and 4) implementation of the statistical analysis. The origin of the research sample was determined as well as the method of the WB calculation, and data on the WB prevalence worldwide was collected in tabular form. The reported size of the research samples varies from 22 to 628 individuals, derived from both contemporary and archaeological populations. Four major formulas were used in order to provide the frequency of WB. The sex of individuals was known in 18 (40.9%) articles. Most of the articles focused on Asian samples. The difficulties in comparing data on the Wormian bones are caused by considerable inconsistency in the methodology used to research this phenomenon. Therefore, the interpopulation comparisons currently made may not be correctly estimated. Our study highlights the need for using more comprehensive and consistent data collection as well as processing protocol suitable for populational research on sutural bones.

Sutural bones or Wormian bones (an unusual anatomical variant associated with inadequate closure of suture) are extra intrasutural irregular isolated bones that occur additionally at center of ossification of the skull; along sutures, around sutures or between the cranial sutures formed by bones of the skull vault. This report displays a case of the presence of an unusual sutural bone at the bregma of the skull of a cadaver during maceration; hence revealing and supporting the possibility of variations in ossification centers and skull matrix which could aid neurosurgeons, orthopedics and radiologists in their practices. The human bregmatic sutural bone presented in this report is a rare occurrence. Considering its location in the skull, it is the first kind reported in Nigeria and Africa as well as one of the few cases reported across the Globe.
