Occipitomastoid suture
Occipitomastoid suture is a cranial suture that connects the occipital bone and the mastoid part of the temporal bone. It is located at the base of the skull and is one of the many sutures that make up the cranium.
Anatomy[edit | edit source]
The occipitomastoid suture begins at the jugular foramen, a large opening in the base of the skull that allows for the passage of several important structures, including the internal jugular vein and several cranial nerves. From there, it extends laterally to the external acoustic meatus, or the opening of the ear canal.
The occipitomastoid suture is a synarthrosis, meaning it is a joint that allows for very little movement. Like all cranial sutures, it serves to connect and secure the bones of the skull, providing protection for the brain and other structures within the cranium.
Clinical significance[edit | edit source]
In some cases, the occipitomastoid suture may be involved in certain medical conditions or procedures. For example, it may be affected by craniosynostosis, a condition in which the sutures of the skull fuse prematurely, leading to abnormal skull shape and potential complications with brain development.
Additionally, the location of the occipitomastoid suture near the jugular foramen means that it may be involved in surgical procedures or other interventions involving this area.
