Coronal suture

Last revised by Assoc Prof Craig Hacking on 17 May 2020

The coronal suture is the cranial suture formed between the two parietal bones and the frontal bone. At the junction of coronal, sagittal and frontal sutures is the anterior fontanelle which is open at birth and usually fuses at around 18-24 months after birth.

Fusion of the coronal suture occurs at around 24 years of age. Premature fusion may result in deformities like oxycephaly and plagiocephaly.
