AIM The premature closure of the metopic suture results in metopic synostosis, also known as trigonocephaly. However, there is a group of children who have only a frontal metopic ridge, obvious with inspection and fingertip palpation, without the clinical features of trigonocephaly. This study aims to report a group of children with metopic ridge with a special emphasis on the definition and th...

Majority of Skull bones are held together by fibrous joints termed as sutures. At birth the two halves of frontal bone remain separate as the metopic suture which is replaced by bone at about 2 years. The persistence of this suture beyond 8 years of age is termed as metopism. The study was conducted on 90 adult human dry skulls. Among them 55 were obtained from department of anatomy RIMS Ongole...

BACKGROUND Metopic craniosynostosis can occur in isolation or in conjunction with other congenital anomalies. The surgical decision making and outcomes between these 2 groups are analyzed. METHODS A retrospective review of all children evaluated in the craniofacial clinic at Seattle Children's Hospital for metopic craniosynostosis between 2004 and 2009 was performed. Physical examination and ...

OBJECTIVE To describe the morphology of the frontal bones and metopic suture at 9-34 weeks of gestation using three-dimensional (3D) ultrasonography. METHODS This was a cross-sectional study of the frontal bones and metopic suture in 16 fetuses at 9-34 weeks of gestation. 3D ultrasonography was used to obtain volumes of the whole fetal skull in the mid-sagittal plane. The volumes were analyze...

Falk and colleagues [Falk D, Zollikofer CP, Morimoto N, Ponce de León MS (2012) Proc Natl Acad Sci U S A 109(22):8467-8470] hypothesized that selective pressures favored late persistence of a metopic suture and open anterior fontanelle early in hominin evolution, and they put an emphasis on the Taung Child (Australopithecus africanus) as evidence for the antiquity of these adaptive features. Th...

The present study has been carried out in fifty-one adult human skulls for metopic sutures in the department of anatomy, Nepalgunj Medical College, Chisapani. Metopic sutures were found in six skulls (11.46%) This study showed higher incidences of incomplete metopic sutures (7.84%). One skull showed double incomplete sutures (one to right of bregma and other in the middle of the frontal bone in...

OBJECTIVE To describe patterns of abnormal development of the metopic suture in association with fetal malformations during the second and third trimesters of pregnancy. METHODS This was a cross-sectional study of the frontal bones and metopic suture in 11 fetuses at 17-32 weeks of gestation. Cases were selected because there were obvious abnormalities in the metopic sutures. In each case, a ...

M oday, Sptem er 6, 2016 CONCLUSIONS: Bitemporal to biparietal ratios are a quantitative, objective clinical measure that can be used to differentiate patients with significant trigonocephaly from those with metopic ridging but no significant cranial deformity. In no case of trigonocephaly did CT scan provide information that would alter surgical planning beyond that obtained from caliper measu...

The metopic suture is located between the tubercles of the frontal bone. There are divergences regarding the exact time at which it closes, which ranges from the first to the tenth year of life, although it may persist into adulthood. This study was conducted on 134 dry crania from adult Brazilians, of which 95 were male and 39 were female. These were available in the anatomy laboratories of hi...

E-Mail: [email protected] Introduction: Metopic suture is present between developing frontal bones. It disappears approximately by 2-3 years and latest by 8 years of age. The persistence of this suture is termed as metopism. It may persist normally without ...
