Parietomastoid suture
Parietomastoid Suture
The Parietomastoid Suture is a cranial suture that is located between the parietal bone and the mastoid portion of the temporal bone. It is one of the many sutures that contribute to the complex structure of the human skull.
Anatomy[edit | edit source]
The Parietomastoid Suture begins at the asterion, a point where the lambdoid suture, occipitomastoid suture, and the parietomastoid suture meet. It extends anteriorly, forming the boundary between the parietal bone and the mastoid portion of the temporal bone.
Clinical Significance[edit | edit source]
Like other cranial sutures, the Parietomastoid Suture can be used as a landmark in neurosurgical procedures. It is also of interest in forensic investigations, as the pattern and timing of suture closure can provide information about age at death.
