伴和不伴鼻息肉的慢性鼻-鼻窦炎患者筛窦的细菌学研究

目的:比较伴和不伴鼻息肉的慢性鼻-鼻窦炎患者及正常对照患者前筛黏膜标本的细菌学特征.方法:在鼻内镜手术中获取前筛黏膜标本,进行需氧和厌氧培养.结果:送检前筛黏膜标本119例,经需氧和厌氧组织匀浆半定量细菌培养,104例标本细菌培养为阳性(细菌培养总阳性率为87.4%);其中慢性鼻-鼻窦炎不伴鼻息肉组(CRSNP-组)、慢性鼻-鼻窦炎伴鼻息肉组(CRSNP+组)、正常对照组需氧或兼性厌氧细菌培养阳性率分别为86.5%、85.7%、90.0%,3组比较差异无统计学意义(P>0.05).3组患者的黏膜标本以需氧菌和厌氧菌混合感染为主,混合感染率分别为CRSNP-组78.4%、CRSNP+组81.0%、对照组85.0%,差异无统计学意义(P>0.05).3组最常见需氧菌株为凝固酶阴性葡萄球菌、棒状杆菌属细菌,比较差异均无统计学意义(均P>0.05).厌氧菌培养阳性率3组分别为78.4%、76.2%、77.5%,差异无统计学意义(P>0.05);最常见厌氧菌株为丙酸杆菌属细菌、消化链球菌属细菌,差异均无统计学意义(均P>0.05).结论:CRSNP-组和CRSNP+组及对照组患者前筛黏膜标本的细菌学特征无明显差异,细菌感染并非是慢性鼻-鼻窦炎发生鼻息肉这一机制中的惟一因素.

Bacteriology of ethmoidal sinus in chronic rhinosinusitis with and without nasal polyps

Objective:To compare the bacteriologic features of anterior ethmoidal biopsy specimens between chronic rhinosinusitis without nasal polyps(CRSNP-),chronic rhinosinusitis with nasal polyps(CRSNP+) and control patients.Method:The biopsy specimens obtained during the nasal endoscopic surgery were cultured for aerobic and anaerobic bacteria.Result:One hundred and nineteen biopsy specimens were processed for homogenination and semiquantitatively bacterial culture of aerobe and anaerobe.Bacterial culture were pos...
