鼻窦炎是怎样引起的?

来源:华人健康网 | 发布时间:2010-09-16 09:00:13 | www.chinesejk.com
鼻窦炎发生的原因很多,全身的慢性疾病、营养不良、维生素缺乏、内分泌紊乱、烟酒过度或人体劳累、受冻、感冒、呛水等诱因后,机体抵抗力减弱;局部病因为肥厚性鼻炎、中鼻甲肥大、鼻中隔弯曲、鼻中隔矩状突等,均可阻塞中鼻道,影响通气和引流;鼻腔异物、鼻息肉、鼻腔肿瘤、鼻出血纱条填塞过久等亦可阻塞鼻窦开口,影响其引流通畅。局部病灶,如慢性扁桃体炎、腺样体炎。变态反应性鼻炎也是引起鼻窦炎的一个重要因素。也可因邻近组织感染后渐侵入鼻窦,如牙根的炎症,通过牙根附着处缺如的牙槽骨或破坏此处较薄的骨壁,进入上颌窦,引起上颌窦炎。
