Summary
Adenoidectomy normalizes the nasopharyngeal microflora in children with infected adenoids. This surgery reduces key upper respiratory pathogens, with fewer detected during summer months.
Area of Science:
- Microbiology
- Otolaryngology
Background:
- Chronically hypertrophied and infected adenoids harbor significant upper respiratory tract infection (URTI) pathogens.
- Key pathogens include Streptococcus pneumoniae, Haemophilus influenzae, Moraxella catarrhalis, Streptococcus pyogenes, and Staphylococcus aureus.
Purpose of the Study:
- To investigate the microbiological changes in the nasopharyngeal flora following adenoidectomy in children.
- To assess the impact of adenoidectomy on common URTI pathogens.
Main Methods:
- Microbiological analysis of the posterior nasopharyngeal wall in 90 children undergoing adenoidectomy.
- Comparison of pre- and post-operative nasopharyngeal microflora.
Main Results:
- Adenoidectomy significantly altered the nasopharyngeal microflora, shifting it towards a more normal composition.
- A reduction in the prevalence of major URTI pathogens was observed post-adenoidectomy.
- Nasopharyngeal pathogen load demonstrated seasonal variation, decreasing in the summer.
Conclusions:
- Adenoidectomy is an effective intervention for normalizing nasopharyngeal microflora in children with chronic adenoid issues.
- The procedure leads to a reduction in key bacterial pathogens associated with URTIs.
- Seasonal patterns influence the presence of nasopharyngeal pathogens, with lower levels noted in summer.
