The second most common type of craniosynostosis is called coronal synostosis, which occurs when one or both of the two frontal bones fuse to one or both of the parietal bones along the coronal suture, which runs across the middle of the head, roughly from ear-to-ear. The 3D images demonstrate normal appearance of the bilateral coronal and lambdoid sutures and normal appearance of the sagittal suture (Figure (Figure1A). Bicoronal craniosynostosis is a type of craniosynostosis which may be part of a syndrome (collection of symptoms often seen together) or non-syndromic.

Her systemic examination and . Coronal. Coronal Craniosynostosis is a premature closure of the skull sutures that lie behind the forehead and run from side to side.

Unilateral coronal craniosynostosis causes about 15% of all isolated craniosynostosis cases. This will, in turn, make the eyes appear as if they are sticking out. Evolution of Cranioorbital Shape in Nonsyndromic, Muenke, and Saethre-Chotzen Bilateral Coronal Synostosis: A Case-Control Study of 2-Year Outcomes. Many of the more profound craniofacial deformities occur secondary to craniosynostosis or premature fusion of one or more cranial sutures. Pediatric Bicoronal Synostosis (brachycephaly) Fusion of both coronal sutures leads to a head shape called "bracycephaly.".
