The analysis of the maxillary sinus volumes and the nasal septal deviation in patients with antrochoanal polyps

摘要

The aim of this study was to evaluate the relationship between the maxillary sinus volumes and the nasal septal deviation angles in patients with antrochoanal polyps (ACP). 76 patients who underwent ACP surgery were included in the study. Of those 36 patients who had multislice computed tomography (MSCT) were evaluated to calculate maxillary sinus volume. The records of paranasal MSCT of 36 healthy people without any paranasal sinus diseases or surgery constituted age- and gender-matched healthy controls. Maxillary sinus volumes and septal deviation angles were calculated using the paranasal MSCT volume-rendering technique. Thirty-six patients in the ACP group were compared with 36 polyp side-matched healthy people. The mean age was 16.6 +/- A 6.7 years in both groups. Statistically, the mean value of the maxillary sinus volume was significantly higher in the ACP group compared with the ACP side-matched control group (15.1 +/- A 4.6 versus 12.0 +/- A 3.5 mm(3)) (p = 0.002). Furthermore, the mean value of the maxillary sinus volume in the non-polyp side (14.2 +/- A 4.7 mm(3)) was statistically higher in the ACP group compared with the side-matched control group volume (11.9 +/- A 3.8 mm(3)) (p = 0.024). In addition, Fifty-three of 76 ACP patients had septal deviation. While the septal deviation was on the same side with the ACP in 17 patients, it was on the opposite side in 36 patients. In conclusion, the maxillary sinus volumes increased in ACP patients compared with the healthy control group. Many patients had nasal septal deviation on the opposite side of the ACP.
