The metopic suture (MS) lies on the midline of the forehead and extends from the frontal bone to the root of the nose. The aim of the current study was to evaluate morphologic features of the complete and incomplete MSs of skulls in the West Anatolian population and rates of the suture types. One hundred sixty crania of West Anatolian people with unknown ages and sex belonging to the anatomy department laboratory of Dokuz Eylul University Medical School were examined. When the MSs that extend from the nasion to the bregma are complete, this condition was named as metopism. The length of the complete sutures was measured using a flexible millimeter calibrated ruler. If the suture was not present throughout between these 2 landmarks (nasion and bregma), these were considered as the incomplete MSs. The incomplete MSs were classified as linear, V-shaped, and double types. The incidence of the complete and incomplete sutures was 75%. The complete (metopism) and incomplete MSs were found in 7.50% and 67.50% of the skulls, respectively. The most common type was linear (39.40%), followed by double shaped (23.10%) and V shaped (5%). The mean length of the complete MS was 12.30 cm. Because the localization and types of MSs are important during clinical approaches, while evaluating patients with head trauma in the emergency department, these should be considered.
