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 Eylül 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.
额缝位于前额中线，从额骨延伸至鼻根。本研究的目的是评估安纳托利亚西部人群颅骨中完整和不完整额缝的形态特征以及缝类型的发生率。对多库兹艾吕尔大学医学院解剖学系实验室的160例年龄和性别不明的安纳托利亚西部人群的颅骨进行了检查。当从鼻根延伸至前囟的额缝完整时，这种情况被称为额缝早闭。使用柔性毫米校准尺测量完整缝的长度。如果在这两个标志（鼻根和前囟）之间缝不是全程存在，则将其视为不完整额缝。不完整额缝分为线性、V形和双形。完整和不完整缝的发生率为75%。完整（额缝早闭）和不完整额缝分别在7.50%和67.50%的颅骨中发现。最常见的类型是线性（39.40%），其次是双形（23.10%）和V形（5%）。完整额缝的平均长度为12.30厘米。由于额缝的定位和类型在临床处理过程中很重要，因此在急诊科评估头部外伤患者时应予以考虑。
