Abstract

BACKGROUND AND OBJECTIVES: This study was designed to investigate the relationship between the sinus mucosal hypertrophy and ciliary beat frequency (CBF) in patients with chronic sinusitis in vitro.
MATERIALS AND METHODS
In 14 patients with chronic sinusitis, mucosal samples were obtained from the superior, inferior, and lateral walls of the maxillary sinus. Using a video-computerized analysis technique, we measured two parameters for ciliary activity at five different sites selected randomly from each sample=the ciliated area (%) showing CBF equal to or higher than 10 Hz (A10) and the weighted frequency (Fw). Mucosal hypertrophy of the maxillary sinus was calculated using a computer program on CT scans.
RESULTS
A(>or=10) and Fw were 91% and 11.3 Hz in control group, respectively, whereas they were 47% and 9.1 Hz in chronic sinusitis group, respectively (p=0.03). There was a significant inverse correlation between A(>or=10) or Fw and mucosal hypertrophy of the maxillary sinus (p=0.001).
CONCLUSION
The results of this study suggest that the severity of mucosal hypertrophy on CT scan may correlate with the ciliary activity.
