目的:通过CBCT观测上颌窦内壁间隔的解剖特点及分布规律。方法:调取苏州口腔医院放射科接受CBCT扫描的汉族患者的CT图像资料360例。Mimics 17.0软件对上颌窦进行三维重建。对上颌窦间隔的发生率、数目、形态、位置及双侧分布状况进行观测。结果:360例中,上颌窦间隔的人群总发生率为37.8%,双侧发生占34.6%,双侧相关系数tau值为0.357(P<0.01)。分布位置常位于磨牙区。不同性别组、年龄组、牙列缺失缺损及牙列完整组间发生率的差异无统计学意义(P>0.05)。结论:上颌窦间隔在汉族人具有较高的发生率,了解其解剖特点及分布规律具有重要的临床意义。
OBJECTIVE: To observe the anatomic features and distribution of maxillary sinus wall space by CBCT. Methods: 360 cases of CT images of Han patients undergoing CBCT scans were collected from Department of Radiology, Suzhou Stomatological Hospital. Mimics 17.0 software 3D reconstruction of the maxillary sinus. The incidence, number, shape, location and bilateral distribution of maxillary sinus space were observed. Results: In 360 cases, the total incidence of maxillary sinus space was 37.8%, bilateral occurred in 34.6%, bilateral correlation coefficient tau was 0.357 (P <0.01). Often located in the molar area. There was no significant difference in the incidence of different gender groups, age group, missing dentition and intact dentition group (P> 0.05). Conclusion: Maxillary sinus space in Han people have a high incidence, understanding of its anatomical characteristics and distribution has important clinical significance.
