Diagnostic Accuracy of Nasopharyngeal Swabs in Detecting Biofilm‐Producing Bacteria in Chronic Adenoiditis

Abstract

In comparison with biopsy, nasopharyngeal swabs seem to be inaccurate in detecting BPB and should be cautiously used in clinical practice. As these preliminary findings may have been due to the well-known resistance of biofilm to mechanical injuries (such as swab rubbing) or the small study population, they need to be confirmed in larger patient series.
