BACKGROUND: Nasal endoscopy allows the collection of middle meatus secretion samples
and is an alternative method for determining microorganisms in rhinosinusitis. This
study assessed endoscopically collected middle meatus secretions in patients with
chronic rhinosinusitis (CRS) and compared those findings with ipsilateral maxillary
sinus aspirates and microbiological data of healthy individuals. METHODS: Middle
meatus samples were collected from 114 CRS patients for aerobic, anaerobic, and
fungal cultures; maxillary sinus secretions were collected from 13 of these patients.
Twenty-three healthy volunteers served as controls. RESULTS: Aerobes were isolated
in 86% of CRS patients, anaerobes were isolated in 8% of CRS patients, and fungi
were isolated in 11% of CRS patients; the most frequent microorganisms were Staphylococcus
aureus (36%), coagulase-negative Staphylococcus (20%), and Streptococcus pneumoniae
(17%). Middle meatus and maxillary sinus cultures presented the same pathogens in
80% of cases. In healthy individuals, coagulase-negative Staphylococcus (56%), S.
aureus (39%), and S. pneumoniae (9%) were the most frequent isolates. CONCLUSION:
The culture of endoscopically collected middle meatus secretions is effective in
identifying microorganisms in CRS patients.
