鼻腔微生物群对慢性鼻窦炎伴鼻息肉患者鼻内镜手术后鼻功能的影响

Effect of nasal microflora on nasal function after endoscopic surgery in patients with chronic sinusitis and nasal polyps

目的探讨分析鼻腔微生物群对慢性鼻窦炎伴鼻息肉患者鼻内镜手术后鼻功能的影响。方法选取北京市大兴区人民医院2021年5月~2022年5月择期进行鼻内镜手术治疗的88例慢性鼻窦炎伴鼻息肉患者,采用高通量测序技术分析鼻腔内分泌物中微生物群分布情况,将患者分为微生物阴性组24例、细菌阳性组42例和真菌阳性组22例。比较两组视觉模拟量表(VAS)评分、Lund-Kennedy内镜评分及Lund-Mackay CT评分评估患者鼻功能并采用鼻内镜评估鼻黏膜损伤程度,并检测鼻黏膜组织基底膜厚度。结果88例慢性鼻窦炎伴鼻息肉患者鼻腔分泌物中共检出病原菌64例,细菌占比47.73%,真菌占比25.00%。术后三组患者鼻功能评分较术前明显降低,组间两两比较差异具有统计学意义(P<0.05)。细菌阳性组和真菌阳性组鼻黏膜上皮损伤程度和基底膜厚度高于微生物阴性组(P<0.05),但组间比较无差异(P>0.05)。结论鼻腔分泌物中细菌和真菌能影响慢性鼻窦炎伴鼻息肉患者鼻内镜手术后鼻功能恢复,影响鼻内镜手术效果。

OBJECTIVE To investigate the effect of nasal microflora on nasal function after endoscopic surgery in patients with chronic sinusitis and nasal polyps.METHODS There were 88 patients with chronic sinusitis with nasal polyps who underwent elective nasal endoscopic surgery in Daxing District People's Hospital from May 2021 to May 2022.High-throughput sequencing technology was used to analyze the distribution of microf lora in nasal secretions,and the patients were divided into a microbial-negative group(24 cases),a bacteria-positive group(42 cases)and a fungus-positive group(22 cases).Visual analog scale,Lund-Kennedy endoscopic score and Lund-Mackay CT were used to evaluate the nasal function of the patients before and 6 months after surgery,respectively.After surgery,nasal endoscopy was used to evaluate the degree of nasal mucosal injury and the thickness of the basement membrane of the nasal mucosal tissue was measured.RESULTS There were 64 pathogens who were detected in nasal secretions of 88 patients with chronic sinusitis and nasal polyps,accounting for 47.73%of bacteria and 25.00%of fungi.After operation,the nasal function score of the three groups was significantly lower than that before operation,and the pair-to-pair comparison between the three groups had statistical significance(P<0.05).The damage degree and basement membrane thickness of nasal mucosal epithelium in bacteria positive group and fungi positive group were higher than those in microbial negative group(P<0.05),but there was no difference between groups(P>0.05).CONCLUSION Bacteria and fungi in nasal secretions can affect the recovery of nasal function after endoscopic surgery in patients with chronic sinusitis and nasal polyps,and affect the effect of endoscopic surgery.
