Objective: The aim of the study is to investigate coexistence of
Wormian bones with metopism, and vice versa, in adult skulls.
Materials and Methods: A total of 160 dry adult human skulls of
unknown sex and ages were randomly selected from the Gross
Anatomy Laboratory of Medical School of Dokuz Eylul University.
The skulls were examined for presence of metopism, Wormian
bones (WB), and coexistence of WBs with metopism and vice
versa. Topographic distribution of the WBs was macroscopically
evaluated within the skulls including metopism.
Results: The frequency of metopism and WBs in 160 skulls is
7.50% (12/160) and 59.3% (95/160), respectively, P<0.05
The incidence of coexistence of WBs with metopism
was found as 11 of 12 skulls (91.66%), whereas the incidence of
coexistence of metopism with WBs was found as 11 of 95 skulls
(11.58%), P<0.05. There were totally 23 sutures
including WBs in 11 skulls, which had metopism. The
number (%) of metopic skulls for each specific suture including
WBs were found as: 11 lamdoid sutures in 7/11 (63.63%) skulls, 4
lambda in 4/11 (36.36%) skulls, 2 asterion in 2/11 (18.18%) skulls,
1 squamous in 1/11 (9.09%) skull, 2 sagittal in 2/11 (18.18%) skulls,
and 3 parieromsatoid sutures in 2/11 (18.18%) skulls. The
distribution of these 23 WBs in sutures of 11 skulls including
metopisms is determined as follows: 11/23 (47.82%) WBs at
lambdoid sutures [5/23 (21.74%) at the right lambdoid sutures
and 6/23 (26.08%) at the left lambdoid sutures, and 4 pair of 11
WBs bilaterally located]; 4 (17.39%) WBs at lambda; 2/23 (8.69%)
WBs at asterion [1/23 (4.34%) at the right asterion and 1/23 (4.34%)
at the left asterion of 2 diverse skulls]; 2/23 (8.69%) WBs at sagittal
sutures; 1/23 (4.34%) WBs at the left squamous suture; 3/23
(13.04%) WBs at parietomastoid sutures [2/23 (8.69%) at the
right parietomastoid sutures and 1/23 (4.34%) at the left
parietomastoid suture and 1 pair of them bilaterally located;
