Sažetak
The aim of this cross-sectional study was to determine the signs of biofilm in the
maxillary sinus of patients with antrochoanal polyps (ACP), and status of the mucosa on which the
biofilm occurred. Mucosal samples from maxillary sinus in 40 ACP patients who underwent endoscopic
sinus surgery were analyzed histopathologically and by scanning electron microscopy. Results
were compared with maxillary mucosa samples of 40 patients without endoscopic and radiological
signs of sinus disease. The existence of biofilm and its relation to the degree of histopathological
changes according to Terrier classification of chronic mucosal inflammation of maxillary sinus were
statistically analyzed. Biofilm was detected in 23 of 40 (57.5%) ACP patients; the incidence was significantly
lower in the control group (2/40, 5%). Biofilm was not found in type 1 mucosa according
to Terrier classification. In conclusion, biofilm showed a significant incidence in the maxillary sinus
mucosa of ACP patients (57.5%). Occasionally, biofilm can be found in patients with no signs of
sinus disease, but not on histologically normal mucosa. Results of this study support the theory that
biofilm formation does not represent the initial stage of the inflammatory process.
