Abstract
The study of healthy sinus flora has been pursued with Caldwell-Luc, antral puncture, and anterior rhinoscopy. Increasingly, nasal endoscopy has been used to obtain cultures, yet the significance of findings using this technique remains uncertain. Our ability to interpret the growing number of these cultures will be greatly enhanced by determining the results of this technique in patients without sinusitis. The goal of this study is to identify the bacterial flora of the sinuses in 25 healthy volunteers.
Gram stain, aerobic, and anaerobic cultures were performed on swabs taken from the middle meatus and sphenoethmoid recesses. Eighteen cultures were sterile for aerobic organisms. Of the remaining 32 cultures, 41 isolates were retrieved. Predominant aerobes were S. aureus, Staphylococcus coagulase-negative, and diphtheroids; P. acnes was the predominant anaerobe.
