Morphometric and volumetric evaluation of maxillary sinus in patients with chronic obstructive pulmonary disease using cone-beam CT.

Abstract

The purpose of present study is to assess the maxillary sinuses patients with COPD morphometrically and volumetrically using cone-beam computed tomography (CBCT) images and compared these findings according to in age and gender of control groups. CBCT images of 80 individuals that exist from 40 patients with COPD and 40 healthy individuals (6 females, 34 males) in the tomography archive were retrospectively analyzed. The volume and surface area of maxillary sinuses in COPD and control group were measured by semi-automatic segmentation method and obtained findings were statistically examinated according to age, gender. The study was observed that there was no statistically significant difference between the right maxillary sinus area and the groups, but left maxillary sinus and total sinus area of COPD group were observed to be significantly lower than the control group (p < 0.05). Maxillary sinus volume was found to be statistically significantly lower in patients with COPD than in healthy controls (p < 0.05). CBCT is a practical and effective imaging method for the evaluation of maxillary sinuses. It is thought that inflammatory diseases that cause sinonasal changes such as COPD may affect maxillary sinus sizes.
