“…that from Tamil Nadu reported by Vinoth et al (2014), and the Central Indian sample examined by Mangalgiri et al (2010) exhibiting incidences of 68%, 88%, and 53%, respectively.

“…There is considerably more variation among these samples in the incidence of incomplete metopism than in the frequencies of complete metopism (Figure 5). The values reported for two or three population samples are seemingly inordinately high, with the Turkish sample studied by Aksu et al (2014), that from Tamil Nadu reported by Vinoth et al (2014), and the Central Indian sample examined by Mangalgiri et al (2010) exhibiting incidences of 68%, 88%, and 53%, respectively.

“…Thus, Agarwal et al (1979) noted that it was situated “almost exclusively” in the lower part of the frontal above nasion and Yadav et al (2010) reported it to be just above nasion in 95.95% (142/148) of specimens examined by them. In all other studies in which the incomplete suture has been documented, it is clearly located immediately superior to nasion in all cases (Ajmani et al, 1983; Aksu et al, 2014; Andrade et al, 2019; Burrell et al, 2016; Castilho et al, 2006; Chandrasekaran & Shastri, 2011; del Sol et al, 1989; Kumar & Rajshekar, 2015; Maneenin et al, 2013; Mangalgiri et al, 2010; Pilli & Sunder, 2013; Saikia, 2014; Santhosh et al, 2014; Surekha et al, 2016; Vinoth et al, 2014; Zanaty, 2017).…”

“…The incidence of incomplete metopism in the South African sample is 28.8 times higher than its frequency of complete metopism. This difference is exceeded by only two other samples: the Karnataka Indian sample of Andrade et al (2019) at 30Â, and the Tamil Nadu sample of Vinoth et al (2014) at 44Â. At the same time, however, the incidence of incomplete metopism is lower than that for complete metopism in only three samples reported to date-those for Malawi (Odokuma & Igbigbi, 2008), the Bedouin (Arensburg et al, 1977), and India (Sheshgiri & Shisirkumar, 2014).…”

This study documents the incidences of complete and partial metopism and their possible relationship to frontal sinus volume (FSV) in a sample of modern adult black South Africans with a view to evaluating the hypothesis that metopism affects frontal sinus hypoplasia. FSV was measured from CT scans and the incidence of metopism was recorded from direct observations of dried cadaveric crania. The sex of each individual was known. Four linear cranial dimensions were used to compute a geometric mean by which to scale FSV. The incidence of partial metopism (38%) is comparable to that reported for other population samples, although there is considerable variation among these global sample frequencies. It is significantly more common in male than female South Africans. FSV in individuals with complete metopism is smaller than average but not inordinately so. On the other hand, FSV is significantly larger in individuals with partial metopism than in those that do not present with this sutural remnant. The data on FSV in individuals with and without partial metopism contradict the hypothesis that there is a relationship between partial metopism and frontal sinus hypoplasia. As such, the metopic remnant evinced by the Late Pleistocene cranium from Hofmeyr, South Africa is unlikely to be related to its very small FSV.

Metopism, the persistence of the metopic suture in adulthood, is a clinically significant radiographic finding. In addition to masquerading as a fracture of the frontal bone, a persistent metopic suture may be associated with other clinically significant anatomical variations including frontal sinus abnormalities. Several geographically and craniofacially distinct populations have yet to be assessed for the prevalence of metopism. This study aimed to determine the prevalence of metopic sutures in adult crania of diverse populations among which scant research exists. A total of 505 adult crania were examined for the presence of a metopic suture. A total of 13 (2.57%) demonstrated metopism. Among subpopulations, metopism was present in 8.06% (5:62) of European crania, 15.38% (2:13) of East Asian crania, 2.20% (2:91) of Egyptian crania, and 2.86% (1:35) of Bengali crania. Metopism was also found in 1 Chilean, Roman, and Tchuktchi cranium, respectively. Metopism was not seen in crania from individuals of African (non-Egyptian) descent (0:62), Peruvians (0:144), Malayans (0:23), or Mexicans (0:23). Among sexes, metopism was present in 3.77% (8:212) of females and 1.79% (5:279) of males. The prevalence of metopism differs between populations and sexes. The results of this study provide anthropological, developmental, and clinical insight with regard to metopism.
