Superior sagittal sinus thrombosis causes

(D) Otitis hydrocephalus> Adequacy of collateral circulation in the hand Extracranial Complications of Otitis Media: Petrositis# Intracranial Complications of Otitis Media> Extradural abscess> Lateral sinus thrombosis> Otitis hydrocephalus> Meningitis> Brain abscess: temporal lobe; cerebellum> Subdural abscess> Cortical thrombophlebitis# Lateral Sinus Thrombophlebitis (Sigmoid Sinus Thrombosis)> It is an inflammation of inner wall of lateral venous sinus with formation of a thrombus.> Thrombosis of the sigmoid sinus is always secondary to infection in the middle ear or otitis media, or in the mastoid process called the mastoiditis.> During operations on the mastoid process one should be careful about the sigmoid sinus, so that it is not exposed.> Spread of infection or thrombosis from the sigmoid and transverse sinuses to the superior sagittal sinus may cause impaired CSF drainage into the latter and may, therefore, lead to the development of hydrocephalus,> Such a hydrocephalus associated with sinus thrombosis following ear infection is known as otitis hydrocephalus.
