Parietomastoid suture - e-Anatomy - IMAIOS
The squamosal suture (squamous suture) arches backward from the pterion and connects the temporal squama with the lower border of the parietal bone: this suture is continuous behind with the short, nearly horizontal parietomastoid suture, which unites the mastoid process of the temporal with the region of the mastoid angle of the parietal bone.

2023年2月20日 · Asterion corresponds to the posterior end of the parietotemporal suture, the Pterion forming the anterior end. It is used as a surface landmark for the radiological and anthropological measurement of the skull. The sutural anatomy of the asterion is useful in retrosigmoid surgical approaches to the posterior fossa. [1] .

Towards the inferior posterolateral portion of the skull, three sutures can be found: parietomastoid, occipitomastoid, and lambdoid. The parietomastoid suture separates the parietal bones and the mastoid process of the temporal bone, whereas the occipitomastoid lies at the connection of the inferolateral occipital bone with the posterior ...
