Metopic suture patent to nasal root

MedGen UID:
Concept ID:
Anatomical Abnormality
HPO: HP:0005495


The frontal suture divides the two halves of the frontal bone in infants and usually fuses by the age of six years. The suture runs from the bregma (the point on the skull at which the coronal suture is intersected perpendicularly by the sagittal suture) to the nasion or nasal root. This term applies if the suture is widely patent from bregma to nasal root. [from HPO]
