Three-dimensional volumetric analysis of the maxillary sinus: a cone-beam computed tomography study

Background: This study aimed to determine the volumetric size of the maxillary sinus and investigate the effect of gender and age on maxillary sinus volume (MSV) using cone-beam computed tomography (CBCT) images in a Turkish subpopulation. Materials and methods: This retrospective volumetric CBCT study was carried out on 133 individuals (84 females, 49 males) between 8 and 51 years old. MSV was measured using the MIMICS 21.0 software (Materialise HQ Technologielaan, Leuven, Belgium). All statistical analyses were performed using the SPSS 21.0 (SPSS, Chicago, IL, USA) software. Mean and standard deviation of both maxillary sinuses measurements were calculated and compared to gender and age. P values <0.05 were considered to indicate statistical significance. Results: Mean volume of the right maxillary sinus was 13.173 cm 3 , while for the left was 13.194 cm 3 . There was no significant difference between right and left maxillary sinus volumes (p>0.05). There was no significant correlation between MSV and age (p>0.05). It was found that MSV did not change according to gender (p>0.05). Conclusions: Right and left maxillary sinus volumes were not different from each other. Gender and age were not found to be related to maxillary sinus volume.
