Otogenic brain abscess

Otogenic brain abscess is the accumulation of pus in brain tissue complicated by suppurative otitis media mastoiditis. The incidence rate of brain abscess is 80%. It is a serious and dangerous complication. More common in young adults. Abscesses are mostly located in the temporal lobe of the brain and cerebellum. Most of them are caused by cholesteatoma otitis media destroying the tympanic cover, tympanic sinus cover, mastoid process cover or destroying the bone plate of sigmoid sinus and sinus meningeal angle. The inflammation directly invades the brain tissue or enters the brain tissue around the vein; A small number of infections spread into the brain through the blood route, resulting in multiple brain abscesses, which are far away from the primary focus.
