Sphenofrontal suture

Sphenofrontal suture is a cranial suture that is found at the junction of the sphenoid bone and the frontal bone in the human skull.

Etymology

The term "sphenofrontal" is derived from the Greek words "sphen", meaning wedge, and "frontal", referring to the forehead. The term "suture" comes from the Latin "sutura", meaning seam.

Anatomy

The sphenofrontal suture is located at the junction of the sphenoid bone and the frontal bone. It is one of the many sutures that make up the complex structure of the human skull. The sphenoid bone is a butterfly-shaped bone that is located at the base of the skull, in front of the temporal bone and basilar part of the occipital bone. The frontal bone is a bone that makes up the forehead and also extends to form the upper orbit of the eye.

Clinical Significance

The sphenofrontal suture, like other cranial sutures, can be used as landmarks in neurosurgery and radiology. They can also be used to determine age in forensic investigations, as the sutures fuse with age. In some cases, premature fusion of the sphenofrontal suture can lead to craniosynostosis, a condition where the skull bones fuse prematurely, leading to abnormal skull growth.
