Sagittal Sinus Superior

The superior sagittal sinus (syn. sagittal sinus) is a paired anatomical canal that runs in the temporal bone and connects the external auditory canal with the posterior cranial fossa. It is one of three sinus canals that form the inner ear system.

The sagittal sinus is located in the upper part of the temporal bone, in the area between the pyramid of the temporal bone and the squama of the temporal bone. It begins on the outer surface of the temporal bone in the area of ​​the external auditory canal, where it connects to the external auditory canal. It then passes through the temporal bone and ends on the posterior surface of the occipital bone, where it becomes the occipital mastoid process.

Inside the sagittal sinus is the internal auditory artery, which supplies the inner ear and the auditory nerve. In addition, the canal may contain other structures such as veins, nerves and lymphatic vessels.

It is important to note that the sagittal sinus can be susceptible to various diseases such as infections, tumors and other disorders. Therefore, it is important to know its anatomy and function in order to correctly diagnose and treat possible problems.
