侧窦血栓性静脉炎是较常见的耳源性颅内并发症之一。在抗菌素问世前,本病病死率较高,据当时日本学者统计,其致死率为27～53％。应用抗菌素后已降至15％左右。据 Allan(1973)和 Ballenger(1977)统计,其病死率为23～38％,近年变化亦不大。与本病复合其它颅内并发症(约达45％)有一定关系。60年代以来,抗菌素和类固醇激素的普遍应用促进了耐药菌株的出现,产生了种种副作用;甚至由于滥用化学药物,使一部分耳源性颅内并发症呈现“隐蔽现象”。侧窦是颅内最大成对的硬脑膜静脉窦。包括横窦和乙状窦二部分。关于中耳炎与脑静脉窦炎间的密切关系,19世纪初 Lateral sinus thrombophlebitis is one of the more common types of intracranial complications of otogenic origin. Before the advent of antibiotics, the disease mortality is higher, according to Japanese scholars statistics, the fatality rate was 27 ~ 53%. After the application of antibiotics has dropped to about 15%. According to statistics by Allan (1973) and Ballenger (1977), the case fatality rate is 23-38%, which has not changed much in recent years. And the disease complicated with other intracranial complications (about 45%) have a certain relationship. Since the 1960s, the widespread use of antibiotics and steroid hormones has led to the emergence of drug-resistant strains with a variety of side effects. Even some of them have “hidden phenomena” due to the abuse of chemical drugs. The lateral sinuses are the largest paired dural venous sinus in the skull. Including the transverse sinus and sigmoid sinus in two parts. On the close relationship between otitis media and venous sinusitis, early 19th century
