| 目的 应用锥形束计算机断层扫描（CBCT）观察上颌窦底间隔的形态，并分析其与性别、年龄及上颌窦体积的关系。方法 回顾性选择在海军军医大学（第二军医大学）第一附属医院口腔科就诊并拍摄CBCT的375例患者（750个上颌窦）为研究对象。将CBCT图像的DICOM文件数据导入Mimics 22.0软件中重建上颌窦三维图像，对上颌窦体积及上颌窦底间隔的发生情况、位置、高度进行测量，并分析上颌窦底间隔发生率与性别、年龄和上颌窦体积的关系。结果 在750个上颌窦中，130个出现窦底间隔，发生率为17.3%。男性和女性上颌窦底间隔的发生率分别为18.5%（63/340）、16.3%（67/410），差异无统计学意义（P=0.431）；年龄18～30岁、31～45岁、46～60岁、＞60岁组上颌窦底间隔的发生率分别为12.7%（29/228）、16.5%（32/194）、23.1%（36/156）、19.2%（33/172），差异无统计学意义（P=0.058）；上颌窦体积0～10 cm3、11～20 cm3、＞20 cm3组上颌窦底间隔的发生率分别为7.1%（14/196）、19.9%（54/271）、21.9%（62/283），差异有统计学意义（P=0.001）。共检出168个上颌窦底间隔，其中24个（14.3%）位于上颌窦前部、84个（50.0%）位于上颌窦中部、60个（35.7%）位于上颌窦后部，上颌窦前部、中部、后部的窦底间隔高度分别为（5.75±1.84）、（9.08±3.77）、（6.41±1.76）mm，差异有统计学意义（P＜0.001）。结论 上颌窦底间隔的发生率随着上颌窦体积的扩大而增高。CBCT可以提供较准确的上颌窦底间隔的位置和大小等信息，为临床实施上颌窦底提升术提供依据。 |

| Abstract: |
| Objective To observe the morphology of maxillary sinus floor septa using cone beam computed tomography (CBCT), and to analyze its relationships with gender, age, and maxillary sinus volume. Methods Totally 375 patients (750 maxillary sinuses) who underwent CBCT were retrospectively selected from Department of Stomatology of The First Affiliated Hospital of Naval Medical University (Second Military Medical University).The DICOM file data of CBCT images were fed into Mimics 22.0 software to reconstruct 3-dimensional images of maxillary sinuses, and the occurrence, position, and height of maxillary sinus floor septa were observed and the volume of maxillary sinus was measured.The relationships of the maxillary sinus floor septum incidence with gender, age, and maxillary sinus volume were analyzed. Results Of the 750 maxillary sinuses 130 showed sinus floor septa, with incidence of 17.3%.The incidence rates of maxillary sinus floor septa in males and females were 18.5% (63/340) and 16.3% (67/410), respectively, with no significant difference (P=0.431).The incidence rates of maxillary sinus floor septa in the age groups of 18-30 years, 31-45 years, 46-60 years, and ＞60 years were 12.7% (29/228), 16.5% (32/194), 23.1% (36/156), and 19.2% (33/172), respectively, with no significant difference (P=0.058).The incidence rates of maxillary sinus floor septa in the groups with maxillary sinus volumes of 0-10 cm3, 11-20 cm3, and ＞20 cm3 were 7.1% (14/196), 19.9% (54/271), and 21.9% (62/283), respectively, with a significant difference (P=0.001).A total of 168 maxillary sinus floor septa were detected, of which 24 (14.3%) were located in the anterior part of the maxillary sinus, 84 (50.0%) in the middle part, and 60 (35.7%) in the posterior part.The heights of the maxillary sinus floor septa in the anterior, middle, and posterior parts of the maxillary sinus were (5.75±1.84), (9.08±3.77), and (6.41±1.76) mm, respectively, with a significant difference (P＜0.001). Conclusion The detection rate of maxillary sinus floor septa increases with the expansion of the maxillary sinus volume.CBCT can provide accurate information about the position and size of the maxillary sinus floor septa, providing a basis for clinical maxillary sinus floor elevation surgery. |
