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.
