Abstract

The craniosynostosis is the term that designates premature fusion of one or more sutures in the cranial vault and thus causes deformities of cranial base and vault. When a suture fused prematurely, the skull and growing brain beneath the suture are forced to expand in the fused suture area. Between April of 1992 and September of 1999, six patients of bilateral coronary synostosis were operated with frontal bone advancement and calvarial remodeling. The supraorbital bar was reshaped with partial osteotomy, greenstick fracture and interpositioning bone grafts. The frontal bone was divided along the metopic suture and transposed one another to make an esthetic shape of the forehead. The parietal bone was expanded with multiple barrel stave osteotomies and fixed to advanced frontal bone with interpositional bone graft. The six patients were operated at the mean age of 10 months. The mean operation time was about 5 hours and mean transfusion volume was 190 cc. There was no postoperative complications and no need for more revisional operation. For a superior result of correciton of craniosynostosis, early surgical intervention is mandate. Efforts for reducing complications, parents' understanding and periodic follow- up are important factors for successful correction.
