Maxillary sinuses are among the largest paranasal sinuses with various shapes and volumes. The dimensions and volumes of maxillary sinuses play an important role in the surgical treatment plan. The higher levels of pneumatization of alveolar bone lead to the increase of odontogenic sinusitis which cause problems in dental implantation. Therefore, this study aimed to evaluate the relationship between maxillary sinus volume and pneumatization and anatomical factors.
In this cross-sectional study, computed tomography (CT) images of the healthy maxillary sinuses of 199 adult patients were reviewed. Amira software was used for the measurement of sinus volume. Sinus pneumatization of the alveolar bone in coronal CT scan images in the posterior teeth areas was measured. Moreover, anatomical variations of the sinonasal region, such as nasal septal deviation, and size of the ostium were measured and recorded. The Kolmogorov-Smirnov test, the t-test, and the Pearson's and Spearman's correlation coefficients were applied for data analysis.
According to the obtained results, the mean value of the maxillary sinus volume and the alveolar bone pneumatization were 15.54 mm and 3.54 mm, respectively. The mean value of the maxillary sinus volume was statistically higher among males than females (P<0.001). The prevalence of nasal septal deviation, concha bullosa, and maxillary sinus septa were 14.6%, 14.6% and 6% respectively. There were no association between anatomical factors, including the nasal septal deviation, the size of the ostium, concha bullosa, and maxillary sinus septa and maxillary sinus volume and pneumatization. P-value less than 0.05 was statistically significant.
No correlation was observed between the anatomical variations of the sinonasal region and maxillary sinus volume and pneumatization.
上颌窦是最大的鼻旁窦之一，形状和体积各异。上颌窦的尺寸和体积在手术治疗方案中起着重要作用。牙槽骨气化程度的提高会导致牙源性鼻窦炎增加，从而在牙种植中引发问题。因此，本研究旨在评估上颌窦体积、气化与解剖因素之间的关系。
在这项横断面研究中，回顾了199例成年患者健康上颌窦的计算机断层扫描（CT）图像。使用Amira软件测量窦体积。在冠状面CT扫描图像上测量后牙区牙槽骨的窦气化情况。此外，测量并记录鼻窦区域的解剖变异，如鼻中隔偏曲和窦口大小。采用Kolmogorov-Smirnov检验、t检验以及Pearson和Spearman相关系数进行数据分析。
根据所得结果，上颌窦体积和牙槽骨气化的平均值分别为15.54毫米和3.54毫米。男性上颌窦体积的平均值在统计学上高于女性（P<0.001）。鼻中隔偏曲、泡状鼻甲和上颌窦隔的患病率分别为14.6%、14.6%和6%。包括鼻中隔偏曲、窦口大小、泡状鼻甲和上颌窦隔在内的解剖因素与上颌窦体积和气化之间均无关联。P值小于0.05具有统计学意义。
未观察到鼻窦区域的解剖变异与上颌窦体积和气化之间存在相关性。
