应用颌面专用CT显示上颌窦与上颌后牙区关系

Clinical application of special maxillofacial CT in the estimation of relation between maxillary sinus and molar region

目的:探讨应用颌面专用CT(QR-DVT9000NEWTOM)成像技术,显示上颌窦与上颌后牙区关系的意义。方法:对上颌牙齿拔除、种植牙、肿瘤等需要显示上颌窦与上颌后牙区关系的患者,进行颌面专用CT扫描和重建成像。结果:颌面专用CT成像技术能够分别以水平位、矢状位、冠状位、曲面以及3D影像,清楚地显示出上颌窦与上颌后牙区的解剖关系等信息。结论:应用颌面专用CT显示上颌窦与上颌后牙区的关系具有重要的临床意义,更能有效地指导临床手术。

Objective： To discuss the clinical application of special maxillofacial CT （QR-DVT 9000 NEWTOM） in the estimation of relation between maxillary sinus and molar. Methods： Maxillofacial CT scan and secondary reconstruction were performed in the diagnosis of patients who needed to estimate the relation between maxillary sinus and molar. Results： Maxillofacial CT scan and secondary reconstruction could provide maxillary sinus image information on position, morphology and approximate relation. Conclusion： Maxillofacial CT scan and secondary reconstruction could be of important diagnostic value in the estimation of relation between the maxillary sinus and molar and guide maxillofacial surgery effectively.
