Nasal endoscopy allows the collection of middle meatus secretion samples and is an alternative method for determining microorganisms in rhinosinusitis. This study assessed endoscopically collected middle meatus secretions in patients with chronic rhinosinusitis (CRS) and compared those findings with ipsilateral maxillary sinus aspirates and microbiological data of healthy individuals.
Middle meatus samples were collected from 114 CRS patients for aerobic, anaerobic, and fungal cultures; maxillary sinus secretions were collected from 13 of these patients. Twenty-three healthy volunteers served as controls.
Aerobes were isolated in 86% of CRS patients, anaerobes were isolated in 8% of CRS patients, and fungi were isolated in 11% of CRS patients; the most frequent microorganisms were Staphylococcus aureus (36%), coagulase-negative Staphylococcus (20%), and Streptococcus pneumoniae (17%). Middle meatus and maxillary sinus cultures presented the same pathogens in 80% of cases. In healthy individuals, coagulase-negative Staphylococcus (56%), S. aureus (39%), and S. pneumoniae (9%) were the most frequent isolates.
The culture of endoscopically collected middle meatus secretions is effective in identifying microorganisms in CRS patients.
鼻内镜检查可采集鼻中道分泌物样本，是确定鼻窦炎微生物的一种替代方法。本研究评估了慢性鼻窦炎（CRS）患者经鼻内镜采集的鼻中道分泌物，并将这些结果与同侧上颌窦穿刺液以及健康个体的微生物学数据进行比较。
从114例CRS患者中采集鼻中道样本进行需氧菌、厌氧菌和真菌培养；从其中13例患者中采集上颌窦分泌物。23名健康志愿者作为对照。
86%的CRS患者分离出需氧菌，8%的CRS患者分离出厌氧菌，11%的CRS患者分离出真菌；最常见的微生物是金黄色葡萄球菌（36%）、凝固酶阴性葡萄球菌（20%）和肺炎链球菌（17%）。80%的病例中鼻中道和上颌窦培养出相同的病原体。在健康个体中，最常见的分离菌是凝固酶阴性葡萄球菌（56%）、金黄色葡萄球菌（39%）和肺炎链球菌（9%）。
经鼻内镜采集的鼻中道分泌物培养对于鉴定CRS患者的微生物有效。
