The overall mortality rate associated with septic cavernous sinus thrombosis (CST) has decreased from 80% to 100% in the pre-antibiotic era to 20% to 30% since 1940.[1]Ebright JR, Pace MT, Niazi AF. Septic thrombosis of the cavernous sinuses. Arch Intern Med. 2001 Dec 10-24;161(22):2671-6.

Once the acute phase has resolved, recovery is gradual. Up to 30% have serious sequelae, including:[10]Macdonald RL, Findlay JM, Tator CH. Sphenoethmoidal sinusitis complicated by cavernous sinus thrombosis and pontocerebellar infarction. Can J Neurol Sci. 1988 Aug;15(3):310-3.

Morbidity and mortality are especially high when diagnosis and treatment are delayed.[15]Southwick FS, Richardson EP Jr, Swartz MN. Septic thrombosis of the dural venous sinuses. Medicine. 1986 Mar;65(2):82-106.

Early management of the primary source of infection, such as endoscopic sinus surgery for sphenoid sinusitis, is crucial in reducing morbidity and mortality.[13]van der Poel NA, Mourits MP, de Win MML, et al.

There are limited data distinguishing outcomes in septic versus aseptic CST, although, generally, it is thought that outcomes are better in aseptic disease.
