-term children 0 to 24 months of age. We additionally explore the patency and closure frequencies of the metopic suture within each age group studied. We hypothesize that normative ranges of cranial indices, including 2 novel cranial indices proposed in this work, can be extracted from the analysis of 3D CT scans and used as references applicable to multiple types of craniosynostosis. Methods After obtaining institutional review board approval, high-resolution, reconstructed 3D head CT scans obtained in 0- to 24-month-old normal full-term infants were retrospectively

T here is an unusual and interesting variety of craniosynostosis in which prenatal closure of the coronal suture is accompanied by persistent separation of the normally fused metopic suture ( Fig. 1A ). This is usually associated with premature fusion of the sphenoid and orbital bones. There results a characteristic deformity marked by: (1) widening of the biparietal diameter of the head, anteriorly, (2) soft-tissue prominence in the midline of the forehead from the region of the anterior fontanel to the depressed bridge of the nose, (3) concavity of the

investigated abnormal fusion of the sagittal as well as the lambdoid, coronal, and metopic sutures. Several publications have reviewed normal fusion of the metopic suture on CT. 1 , 12 , 15 , 22 , 23 However, there is less information on normal fusion of other major sutures. Most existing information derives from studies of adult cadaveric skulls, 2 , 5 , 14 , 16–21 although there is at least one recent CT study in the forensic literature. 6 With the present publication, we hope to increase the information available about the normal fusion of major calvarial sutures

A radiographic and histological evaluation of calvarial and sutural redevelopment in rabbits

frontal bones, midsagittal suture, metopic suture, and coronal suture. After a thorough irrigation of the surgical field with sterile saline, the periosteal flaps were reapproximated in the midline, and the scalp incision was closed with interrupted sutures. These were removed on the fifth postoperative day. One control and one experimental animal from each group were given a 50 mg/kg injection of tetracycline hydrochloride 1 week prior to sacrifice and on the day before sacrifice. Animals younger than the 12-week postoperative group received intraperitoneal

the clinical features of these children have been summarized, but the frequency of trigonocephaly due to metopic craniosynostosis often has been underreported (or underrecognized). Although there are many known syndromic forms of craniosynostoses (for example, Apert, Crouzon, Pfeiffer, and Saethre—Chotzen syndromes), none has been shown to be associated with prenatal maternal drug use. Trigonocephaly is a congenital defect affecting at least one in 15,000 live births. 10 This type of craniosynostosis, which involves the metopic suture, is characterized by a

C raniosynostosis syndrome is a congenital anomaly of the cranium with an incidence of 4–5 per 10,000 live births. 8 Craniosynostosis occurs as 2 types: nonsyndromic craniosynostosis, involving only dysmorphology of the cranium with no familial history, and familial syndromic craniosynostosis, which shows autosomal-dominant inheritance and is associated with other anomalies such as facial hypoplasia or anomaly of the extremities. We treated a young boy who presented with complex multisuture craniosynostosis involving the metopic suture and bilateral

. Metopic Synostosis Two children had an isolated metopic synostosis, and two had the combined type, with bilateral coronal synostosis in both and anterior sagittal synostosis in one ( Tables 2 and 3 ). Both patients with isolated metopic synostosis had an anteriorly pointed cranial vault typical of trigonocephaly. Metopic sutures were not visible on axial CT slices in any patient. One of the children with isolated metopic synostosis had marked sclerosis and enostosis at the metopic suture site. The other had marked localized bone thickening at the suture site within

among a larger group of patients with multiple synostoses because they did not have any of the phenotypical features of a wellknown syndrome. Forty-eight sutures were involved and the most commonly affected suture was the coronal suture (38 cases) followed by the sagittal suture (11 cases), the metopic suture (6 cases), and the least involved, the lambdoid suture (3 cases). The first patient underwent surgery in January of 1998 and the last in March 2009. The follow-up duration ranged from 3 to 135 months (mean of 61 months) ( Table 1 ). Following surgery, head scans

T rigonocephaly is a relatively rare form of craniosynostosis, with an incidence of 7 per 2500 live births, and accounts for 7%–23% of most large series. 3 , 29 It results from premature fusion of the metopic suture, which may be secondary to intrauterine compression, or shaping of the cranial suture complex by subjacent dura mater, with temporal and spatial supply of osteoinductive growth factors and cellular elements to the suture mesenchyme. 10 , 33 , 45 , 46 Surgery is often required for cosmetic correction of the resultant deformity.

M etopic synostosis is the second most common type of craniosynostosis, and it can be nonsyndromic, occurring in isolation or with fusion of other sutures, or it may occur as part of a dysmorphogenic syndrome such as Crouzon or Saethre-Chotzen syndrome. 12 , 15 The metopic suture is the first to fuse physiologically, with complete closure typically occurring by 9 to 11 months. 16 , 17 Premature fusion is characterized by restricted growth of the frontal bones, resulting in a prominent midline ridge with a triangular forehead and bitemporal narrowing and
