Among the sampling methods used to investigate the pathogens responsible for rhinosinusitis, maxillary sinus puncture is considered to be the gold standard. Although endoscopic middle meatal culture seems to correlate well with the results obtained by maxillary sinus puncture, the reliability of documentation of bacteria by endoscopic culture in children with rhinosinusitis is still unknown. Finally, because studies on current bacterial resistance patterns in pediatric patients are limited, we employed maxillary sinus puncture to obtain sinus secretions for bacterial culture and analysis of antibiotic resistance in children with chronic rhinosinusitis.

关於鼻窦的培养方法，一般而言上颌窦穿刺为公认获得鼻窦细菌培养的准则，虽然证据显示在成人使用内视镜中鼻道培养的结果与上颌窦穿刺所获得的培养结果相关性很高，不过目前儿童使用内视镜中鼻道培养的可信度依然不明，因此我们的研究也比较鼻及鼻窦炎病童上颌窦穿刺与内视镜中鼻道培养的结果，以厘清在儿童使用内视镜中鼻道采样培养鼻窦致病菌的可信度。
