To evaluate the accuracy of endoscopically guided middle meatal aspiration culture by comparing the culture results between middle meatal aspiration using the modified aspiration instrument and direct maxillary antral tap.
Sixteen patients with chronic rhinosinusitis underwent functional endoscopic sinus surgery (FESS) were enrolled. Both endoscopically middle meatal aspiration culture (EMAC) using modified aspiration instrument and direct antral tap culture (ATC) were performed before FESS. Microbiologic data were compared and analyzed for any statistical differences between EMAC and ATC.
The positive culture rates were 93.75% in both EMAC and ATC groups. Aerobic and facultative anaerobic bacteria were found in 87.5% of EMAC group and 81.25% of ATC group. The two most common bacteria in both groups were coagulase-negative Staphylococcus and Staphylococcus aureus. The association between EMAC and ATC was strong to moderate (13/16) 81.25%.
EMAC appears to be a valuable alternative to ATC for guiding bacterial-specific therapy in chronic rhinosinusitis. This modified aspiration instrument should be useful in clinical practice and serve as a cost effective procedure.
通过比较使用改良抽吸器械进行中鼻道抽吸培养与直接上颌窦穿刺的培养结果，评估内镜引导下中鼻道抽吸培养的准确性。
纳入16例接受功能性鼻内镜鼻窦手术（FESS）的慢性鼻窦炎患者。在FESS术前，分别采用改良抽吸器械进行内镜下中鼻道抽吸培养（EMAC）和直接上颌窦穿刺培养（ATC）。对微生物学数据进行比较和分析，以确定EMAC和ATC之间的任何统计学差异。
EMAC组和ATC组的阳性培养率均为93.75%。EMAC组87.5%的患者和ATC组81.25%的患者检测到需氧菌和兼性厌氧菌。两组中最常见的两种细菌是凝固酶阴性葡萄球菌和金黄色葡萄球菌。EMAC与ATC之间的关联强度为强到中度（13/16），占81.25%。
对于慢性鼻窦炎的细菌特异性治疗，EMAC似乎是ATC的一种有价值的替代方法。这种改良的抽吸器械在临床实践中应是有用的，并且是一种具有成本效益的方法。
