Sutura coronalis

Sutura Coronalis is a fibrous joint that separates the frontal bone and the parietal bone in the human skull. It is one of the major cranial sutures and plays a crucial role in the growth and development of the skull during infancy and childhood.

Anatomy

The sutura coronalis, also known as the coronal suture, runs transversely across the skull, from one temporal bone to the other. It is located superior to the sphenoid bone and anterior to the sagittal suture. The coronal suture is a type of synarthrosis joint, which means it is immovable under normal conditions.

Development

During infancy, the sutura coronalis is not fully fused, allowing for the rapid growth of the brain and skull. This suture begins to close during the first year of life and is usually completely closed by adulthood. The timing of suture closure can vary greatly among individuals and is influenced by various factors, including genetics and environmental conditions.

Clinical Significance

Premature closure of the sutura coronalis, a condition known as craniosynostosis, can lead to abnormal skull shape and potentially cause increased intracranial pressure, developmental delays, and other health problems. Treatment for craniosynostosis often involves surgery to reopen the suture and allow for normal brain and skull growth.
