“…This nding corroborates with previous studies [10,13,17]. On the other hand, other studies [2,17,18,23] found a signi cantly higher maxillary sinus volume in males, which was explained by the greater proportions of the male face.…”

“…This result was also seen in the work by Okşayan et al, where the hypodivergent vertical growth pattern group showed signi cantly better results than the hyperdivergent group in the right maxillary sinus length parameter (p < 0.05) [11]. Based on the sagittal skeletal pattern, Shrestha et al [23] found that the maxillary sinus volume in Class II individuals was signi cantly larger than that in Class III individuals. In our study, we found the opposite result, with Class III individuals having a signi cantly larger maxillary sinus volume than Class II individuals.…”

Purpose: To investigate whether there is a relationship between the volume of the maxillary sinus and individual parameters such as sex, side, posterior tooth absence, sinus membrane thickening, bony septa, and vertical and sagittal skeletal patterns.Methods: The tomographic volume of the maxillary sinus from 211 individuals (422 sides) was evaluated using Horos DICOM Viewer software. Bone septa and sinus membrane thickening were classi ed as absent or present, while maxillary posterior dental absence was de ned as the absence of one or more teeth in the posterior region of the maxilla (except for the third molars). The test-test was applied to analyze maxillary sinus volume according to sex, age, side, posterior tooth absence, sinus membrane thickening, and bony septa. For comparison of sagittal and vertical patterns, a one-way analysis of variance (ANOVA) with Tukey's post-hoc test was applied.Results: No statistically signi cant differences were observed between the maxillary sinus volume according to gender (p=0.06), side (p=0.37), posterior tooth absence (p=0.92), sinus membrane thickening (p=0.47), bony septa (0.89) and vertical skeletal pattern (p=0.67). In relation to the sagittal skeletal pattern, a statistically signi cant difference was observed between Classes II and III (p=0.05).Conclusion: Maxillary sinus volume was in uenced only by the sagittal skeletal pattern and was higher in Class III individuals.

“…25 In another study evaluating the maxillary sinus volume in different craniofacial patterns, it was reported that maxillary sinus volume is significantly larger in skeletal class II than in skeletal class III group and also the volume of the maxillary sinus was higher in men. 26 In a study evaluating maxillary sinus changes after Le Fort I osteotomy, a decrease in maxillary sinus volume and an increase in sinus membrane thickness were observed. They concluded that Le Fort I osteotomy affected the volume and thickness of the maxillary sinuses.…”

Aim:The purpose of this study was to investigate the factors influencing the volume of healthy maxillary sinuses by cone beam computed tomography (CBCT). Material and Methods:The maxillary sinus volumes of healthy and entirely visible on the CBCT scan of patients over 18 years of age were evaluated bilaterally using NNT Viewer volumetric software (CeflaGroup, Verona, Italy). The images with pathologic changes in one or both maxillary sinuses were excluded. The study included 200 healthy maxillary sinuses of 100 patients (65 female and 35 male) aged between 19 to 85 years with a mean age of 44.13±16.36 years. The status of the dentition in the posterior maxilla in regards to the maxillary sinus was classified as dentate, partially dentate and edentulous. Differences in volume based on gender, age, sinus side, and dental status were analyzed statistically. Results: There were 104 (52%) dentate sinuses and 76 (38%) partially dentate and 20 (10%) edentulous sinuses. Males had significantly larger maxillary sinus volumes compared to females (p<0.05). There was an inverse and rather weak (15%) but statistically significant relationship between age and sinus volume (p<0.05). There was no difference in volume between the right and left sinuses and dental status showed no differences in sinus volume (p<0.05). Conclusion:Gender and age influence healthy maxillary sinus volume, while sinus side and dental status do not. Although it has been reported that the maxillary sinus volume increases throughout life after removal of the posterior teeth in the upper jaw, we found in our study that tooth loss was not associated with the ongoing pneumatization of the maxillary sinus. To validate this finding, there is a need for prospective studies comparing sinus volumes using standard time intervals before and after tooth extraction in the posterior maxilla.

“…This cross-sectional study included the same sample as the authors’ previous study. 13 No subjects received CBCT scans purely for the purposes of this study. The Institutional Review Board of the Third Affiliated Hospital of Sun Yatsen University reviewed and approved the protocol for this study, and the study was conducted in accordance with the Helsinki Declaration, as amended in 2013.…”

Purpose This study evaluated the distance from the posterior root apices to the maxillary sinus floor (MSF) and the frequency of roots touching or protruding through the MSF using cone-beam computed tomography (CBCT). Materials and Methods This study included 100 subjects divided into different vertical and anteroposterior skeletal growth patterns. On CBCT images, the distance from the posterior root apices to MSF was measured and the frequency of roots touching or protruding through the MSF was evaluated using NNT software (version 5.3.0.0; ImageWorks, Elmsford, NY, USA). Results No statistically significant differences were found in the distance from the posterior root apices to the MSF among vertical skeletal groups ( P >0.05). The palatal roots of the first molar and the palatal, mesio-buccal and disto-buccal roots of the second molars had significantly less distance from MSF in skeletal class II than in class III ( P <0.05). The high-angle group had the highest frequencies of roots touching or protruding into the maxillary sinus (49.8%); the lowest proportion of these roots was found in skeletal class III (28.3%) and the highest proportion in class II (50.3%). Males had shorter distances from the posterior root apices to the MSF and higher frequencies of roots protruding through or touching the MSF than females. Conclusion Anteroposterior skeletal growth patterns and sex affected the distances from the maxillary posterior roots to the MSF. The frequency of roots protruding into or touching the sinus was affected by both vertical and anteroposterior skeletal groups and sex. These findings have implications for dental practice.
