Background: Cranial sutures are syndesmosis between the cranial bones. The coronal suture is oblique in direction and extends between the frontal and the parietal bones. Craniosynostosis is a rare birth defect that occurs when the coronal suture in the skull fuses prematurely, but the brain continues to grow and develop. This leads to a misshapen head. There are a number of forms of this defect, such as coronal, sagittal, lambdoid, and metopic. Materials and Methods: Total 500 skulls were used for study, coronal suture length measured by thread method, distance between Nasion to bregma and midsupraorbital rim to coronal suture were measured. For finding skull with absence of coronal, sagittal, lambdoid, and metopic suture, we examined many skulls during routine osteology classes of Medical, Dental and other medical sciences students. Around 500 skull observed and we find only one skull with absence of left coronal suture completely. Results: The length of coronal suture was 24.8+1.4cm length, the distance between nasion to bregma was 126.7 +10.25 mm and Midsupraorbital rim to cranial suture was 102.76+8.64mm We have found only one skull with absence of coronal suture. Some of the skulls shows partly fusion of sagittal, coronal sutures. The skull with complete absence of coronal suture showing the features of other sutures clearly and right side of coronal suture is showing the complete suture. The skull was not damaged and it is in perfect condition which was using by students for their osteology study. Conclusion: We found the skull with absence of left coronal suture, which may resulted due to craniosynostosis. It may be due to hot climate in India also might be resulted for absence of suture.

Surgical Release

✓ Premature closure of a cranial suture results in skull deformation characterized by inhibited skull growth in a direction perpendicular to the course of the affected suture. Early surgical release of the closed suture results in a “normal” skull morphology. The present experimental study measured alterations in growth at the transverse cranial sutures that occurred following induced premature closure of the coronal suture and its subsequent release in New Zealand White rabbits. Using roentgenocephalometric methods, growth and morphometric changes were monitored at the frontonasal, coronal, and anterior lambdoid sutures following premature closure of the coronal suture at 9 days of age. The results indicated that premature closure of the coronal suture did not result in compensatory (increased) growth at the other transverse sutures of the vault. In fact, growth at these sutures was significantly reduced. This reduced growth at adjacent transverse sutures was not ameliorated by early surgical release of the fused suture.

Experimental Group

The purpose of the present study was to observe the response and changes of cranial suture to the distraction forces in growing goats and to examine the expression patterns of TGF-β and BMP during suture distraction.Twenty growing goats were divided into three groups: control (n=4), experimental (n=12), and sham (n=4). A pure titanium distractor was placed in the coronal suture in both the sham and experimental groups. After healing, the distractor was activated for distraction of the coronal suture at a rate of 0.5 mm/day for 8 days in the experimental group. Three animals were killed respectively, at 0，2，4 and 8 weeks after completion of suture distraction. No force was applied in the sham group. X- Ray examination was taken and the coronal suture samples were harvested and processed for histological analysis and scanning electron microscopic analysis and immunohistochemistry of TGF-β and BMP. The coronal sutures of experimental group were separated successfully. Signs of intramembranous bone formation and remodeling were found in the distracted suture，and the sutural structure almost return to its normal state at 8 weeks after end of distraction. At 0 and 2 weeks after completion of suture distraction, the collagen fiber bundles were strengthened and aligned in the direction of the distracted forces. Strong expression of BMP and TGF-β were detected in the fibroblast-like cells and the active osteoblasts. At 4 weeks after suture distraction, signs of intramembranous ossification were found in the edge areas of the distracted suture, and the positive staining of BMP and TGF-β was still noted in the osteoblasts around the newly formed bone trabeculae. This study suggests that cranial suture expansion can be achieved in growing animal by distraction osteogenesis. Mechanical strain resulted from distractor can induce the adaptive remodeling in the cranial suture of growing goats. It also suggests BMP and TGF-β may play very important roles in the process of bone formation and remodeling during suture distraction osteogenesis.

Craniofacial growth data from craniosynostotic children have shown that suture immobilization results in predictable restrictions of cranial vault growth in a direction perpendicular to the affected suture and compensatory growth at sutures perpendicular to the affected one. This study tests these predictions by using rabbits with nonsyndromic congenital coronal suture synostosis. Data were collected from 96 rabbits divided into three groups: 42 unaffected litter mate controls, 33 partially synostosed rabbits, and 21 completely synostosed rabbits. Markers were placed bilaterally on either side of the vault sutures at 1.5 weeks of age. Serial radiographs were taken at 1.5, 6, 12, and 18 weeks of age for assessment of growth at the vault sutures and of various cranial landmarks. Results revealed that completely synostosed animals had significantly (p <.05) shorter cranial vaults, reduced growth at the coronal suture, and increased growth at the sagittal, frontal, and squamosal sutures compared with unaffected rabbits. Results also showed that the calvarial growth observed in this craniosynostotic rabbit model closely reflects predicted compensatory patterns seen in human clinical populations and that this rabbit model is valuable for understanding the pathogeneses and craniofacial growth patterns of humans with premature cranial suture synostosis.

Scientific Principles

Craniosynostosis, the premature closure of cranial sutures, has been known to exist for centuries, but modern surgical management has only emerged and evolved over the past 100 years. The success of surgery for this condition has been based on the recognition of scientific principles that dictate brain and cranial growth in early infancy and childhood. The evolution of strip craniectomies and suturectomies to extensive calvarial remodeling and endoscopic suturectomies has been driven by a growing understanding of how a prematurely fused cranial suture can affect the growth and shape of the entire skull. In this review, the authors discuss the early descriptions of craniosynostosis, describe the scientific principles upon which surgical intervention was based, and briefly summarize the eras of surgical management and their evolution to present day.

Premature Closure

Craniosynostosis refers to skull deformities secondary to the premature closure of cranial suture. Isolated or multiple sutures craniosynostosis is more common than syndromic craniosynostosis. Deformities with synostosis are stigmatizing, and this provides a strong aesthetic indication for surgical correction in the non-syndromic group of patients. We present a case of non-syndromic sagittal synostosis in a ten months old patient underwent open surgical repair for skull deformity.International Journal of Human and Health Sciences Vol. 05 No. 02 April’21 Page: 254-257
