Metopic suture is a dense fibrous joint extending from nasion to bregma. Normally, closure of this suture takes place between 1-8 years of age. Failure of this closure beyond 8 years leads to persistent metopic suture. Persistent metopic suture may mimic skull fracture.
To differentiate metopism from frontal bone fracture.
54 dry skull of adult humans in were studied. These skulls were observed for the presence (complete or incomplete suture) or absence of metopic suture.
Metopic suture was found in 3.7% skulls. Both complete and incomplete metopic suture were found in 1.85% of the dry skulls.
Neurosurgeons, radiologists, otorhinolaryngologists, physicians, anatomists, forensic specialists, anthropologists and evolutionary biologists should have knowledge of this anatomical variation. This case series focusses on the importance of metopism. Metopism is a topic, which has not been much studied.
额缝是一条从鼻根延伸至前囟的致密纤维性关节。通常，这条缝在1至8岁之间闭合。8岁以后这条缝仍未闭合会导致额缝持续存在。持续存在的额缝可能会被误诊为颅骨骨折。
鉴别额缝未闭与额骨骨折。
研究了54个成人干燥颅骨。观察这些颅骨是否存在（完全或不完全缝）额缝。
在3.7%的颅骨中发现了额缝。在1.85%的干燥颅骨中发现了完全和不完全额缝。
神经外科医生、放射科医生、耳鼻喉科医生、内科医生、解剖学家、法医专家、人类学家和进化生物学家都应该了解这种解剖变异。本病例系列关注额缝未闭的重要性。额缝未闭是一个研究较少的课题。
