Evaluation of septas in maxillary sinus with conebeam computed tomography.

Aim: The aim of the study was to examine the prevalence of maxillary sinus septa (MSS) in a Turkish population, using cone-beam computed tomography (CBCT). Methodology: The CBCT images of 350 untreated patients (178 male, 172 female ranging in age between 18 and 65) were included in this study. The presence or absence of MSS was determined in axial, sagittal, and coronal planes by considering gender and side. For statistical evaluation, a chi-square test was used to determine any differences in the prevalence of MSS with significance set at 5%. Results: MSSs were observed in 201 out of 700 sides (28.71%) and 141 out of 350 patients (40.28%), of which, 70 were in males and 71 in females. MSS were also observed in a higher prevalence on the bilateral side. (17.14%). Female patients showed higher prevalence (41.27%) than the male patients (39.32%). Conclusions: MSS was observed in 40.28% of examined Turkish subjects and detected more frequently in females and on the bilateral side. [ABSTRACT FROM AUTHOR]
