The squamous suture is a type of cranial suture that connects the parietal bones with the temporal bones on each side of the head. It is also known as the squamosal or squamosomastoid suture.
Cranial sutures are fibrous joints that connect the bones of the skull. They allow for growth and flexibility during development, and eventually fuse as we age, forming a solid structure. The squamous suture specifically joins the flat, scale-like squamous part of the temporal bone with the parietal bone.
The squamous suture is located on the lateral aspect of the skull, extending from the region above the external auditory meatus (ear canal) to the pterion – a point where several bones meet, including the frontal, parietal, sphenoid, and temporal bones.
The squamous suture is important for stabilizing and protecting the brain within the skull. It also plays a role in allowing some movement between the bones during childbirth. Additionally, the squamous suture can be used as a reference point in medical imaging, such as computed tomography (CT) scans, to help identify specific structures and abnormalities in the skull.
Understanding the anatomy and locations of cranial sutures is essential for healthcare professionals, particularly those specializing in neurology, radiology, or surgery. It enables them to accurately diagnose and treat conditions related to the skull and brain.
