With this notion in mild, we can appreciate the importance of maxillary sinus puncture in documenting microbiology of pediatric rhinosinusitis. By this methodology, we demonstrated that α-hemolytic streptococcus, Hemophilus influenzae, Streptococcus pneumonia, coagulase-negative Staphylococcus, and Staphylococcus aureus are the major organisms found in pediatric rhinosinusitis. We also demonstrate a different pattern of antibiotic resistance when comparing to previous studies performed in both children and adults.

有了这样的概念，便可以知道上颌窦穿刺在儿童鼻及鼻窦炎致病菌培养上的重要性，采用这一方法，我们得到的结果显示小儿慢性鼻及鼻窦炎培养出的主要菌株为α-hemolytic streptococcus，Hemophilus influenzae，Streptococcus pneumonia，coagulase-negative Staphylococcus以及Staphylococcus aureus，除了与成人慢性鼻窦炎的菌株不同外，也显示了与先前类似研究不同的抗生素抗药性形态。

Careful nasal endoscopy and CT should be performed on the patients of nasal sinuitis with deep headache or lateral headache complicated with resorptive bloody sputum.

对有深部头痛或一侧头痛患者伴有回吸性血痰等症状的鼻窦炎患者应进行详细的鼻内窥镜检查和鼻窦CT检查，手术中尽量扩大病变的蝶窦开口和上颌窦开口，手术后定期冲洗窦腔是防止复发的关键。

Careful nasal endoscopy and CT should be performed on the patients of nasal sinuitis with deep headache or lateral headache complicated with resorptive bloody sputum.
