中文摘要：

目的报道5例丝状真菌所致真菌性鼻窦炎病例。方法分析5例鼻窦炎患者临床资料,对患者鼻分泌物或鼻黏膜进行真菌直接镜检和培养,对培养获得菌株进行形态学和分子生物学鉴定。结果结合真菌直接镜检、培养和分子生物学方法,确定致病真菌为茄病镰刀菌、烟曲霉、黄曲霉、波氏假阿利什霉和萝卜镰刀菌。4例患者采用鼻内窥镜手术治疗,1例患者采用伏立康唑、两性霉素B控制病情,效果均良好。结论真菌性鼻窦炎致病真菌多样,分子生物学可做准确鉴定,鼻内镜手术治疗效果良好。

英文摘要：

Objective To report five cases of nasal sinus mycoses caused by filamentous fungi and related laboratory investigation.Methods Analyze five clinical cases of nasal sinusitis.Direct smear examination,fungal culture,PCR and sequence analysis were performed for diagnosis.Results Morphological study could not identify fungi to species level but sequences analysis can identify the 5isolates as Fusarium solani,Aspergillus fumigatus,Aspergillus flavus,Pseudallescheria boydii,Fusariam napiforme.Endoscopic surgeries were applied to 4patients;1patient received voriconazole and amphotericin B therapy;treatments were effective to all patients.Conclusions Nasal sinus mycoses could be cause by various fungi.Molecular Biology can identify pathogens to species level,and endoscopic surgery is a reliable treatment for nasal sinus mycoses.
