Abstract:
OBJECTIVE To analyze the distribution of the nasopharyngeal microbiota in children with refractory chronic sinusitis and adenoid hypertrophy using 16S rRNA next-generation high-throughput sequencing technology,and to compare the effects of adenoidectomy on the nasopharyngeal microbiota in such patients,with the aim of providing microbiological evidence for the clinical treatment of refractory chronic sinusitis with adenoid hypertrophy.METHODS Children diagnosed with chronic sinusitis with adenoid hypertrophy who visited Chengdu Women and Children's Central Hospital from January 2024 to March 2025 and whose symptoms were not controlled after drug treatment were selected.They were divided into a non-surgical group and a surgical group based on whether they underwent adenoidectomy.The VAS scores,Lund-Kennedy scores,and microbial community detection rates between the two groups were compared.RESULTS The final VAS scores and Lund-Kennedy scores for surgical group were both lower than those for non-surgical group,with statistically significant differences(tVAS score=3.491,P<0.001;tLund-Kennedy score=4.166,P<0.001).Comparisons of microbial α diversity analysis and β diversity at the phylum and genus levels between the two groups showed no statistically significant differences(tα diversity analysis=0.524,P=0.604;Rβ diversity at the phylum level=0.075,P=0.454;Rthe genus level=0.117,P=0.538).The dominant bacterial groups at the phylum level were the same in both groups,including Proteobacteria,Bacillales,Actinobacteria,Bacteroidetes,and Firmicutes,but the average relative abundance differed between the two groups.Species comparison analysis showed that at the phylum level,the abundance of Proteobacteria and Thermodesulfovibrio in surgical group was higher than that in non-surgical group;At the genus level,the abundance of the genus Moraxella was higher in non-surgical group than in surgical group,while the abundance of the genera Acidovorax,Stenotrophomonas,Delftia,Burkholderia,Caballeronia,Paraburkholderia,Lactobacillus,Devosia,norank_f_Muribaculaceae,Paracoccus,and Kocuria was lower in non-surgical group than in surgical group.CONCLUSION Children with refractory sinusitis and adenoid hypertrophy all have rich microbial communities in the nasopharynx.Adenoid surgery has no significant effect on the diversity of the nasopharyngeal microbial community.However,the composition of the microbial community has changed,and there are significant species differences,which may be related to the resolution of local obstruction after adenoidectomy and changes in the survival environment of the nasopharyngeal microbial community.
