Dural Venous Sinuses
👩⚕️ For this lesson, just practice drawing a schematic of the dural venous sinuses until you have memorised it.
Schematic of the dural venous sinuses
👩⚕️ And now just a couple of quick Q&As.
A patient sustains head trauma to the vertex with a depressed skull fracture. Which intracranial structure is most likely to be damaged?
Superior sagittal sinus
The superior sagittal sinus is a large venous channel running along the midline, directly under the skull at the vertex, making it susceptible to injury in midline trauma.
Infection from a mastoid abscess can spread to which of the following structures?
Sigmoid sinus
The sigmoid sinus lies in close relation to the mastoid air cells. Infection from a mastoid abscess may spread here, causing lateral sinus thrombosis, a recognised complication of untreated mastoiditis.
