鼻窦解剖上邻近脑膜,鼻窦炎可继发软脑膜炎。近年来鼻源性软脑膜炎有增加趋势,似与症状不典型呈隐蔽性发展的鼻窦炎增多以及未及时合理进行抗生素治疗有关。作者分析1986～1987年收治鼻窦炎116例,发现其中26例(22.4％)并发非化脓性软脑膜炎。大多数(24/26)系在慢性鼻窦炎的基础上发生。其中上颌窦炎10例;上颌窦、筛窦炎2例;额窦炎5例;一侧鼻窦炎5例;全鼻窦炎4例。鼻窦炎的病因主要是细菌感染。上呼吸道粘膜常存在条件致病菌,当机体抵抗力下降时可引起鼻窦炎。文献报导常见致病菌有葡萄球菌和链
Sinus adjacent to the meninges, sinusitis secondary to meningitis. In recent years, there is an increasing trend of nasal soft meningitis, sinusitis seems to be hidden with the development of atypical symptoms of increased and not timely and reasonable antibiotic treatment. The authors analyzed 116 cases of sinusitis from 1986 to 1987 and found 26 (22.4%) of them complicated with non-purulent meningitis. Most (24/26) occur on the basis of chronic sinusitis. Including maxillary sinusitis in 10 cases; maxillary sinus, ethmoid sinus in 2 cases; Frontal sinusitis in 5 cases; side sinusitis in 5 cases; 4 cases of sinusitis. The main cause of sinusitis is bacterial infection. Upper respiratory tract mucosa often exist in conditions of pathogens, when the body resistance can cause sinusitis decline. The common pathogens reported in the literature are staphylococci and chains
