电子束CT三维重建技术与颅颌面外科

Three-dimensional Electron BeamCT Reconstruction Image and Cranio-Maxillo-Facial Surgery

目的探讨电子束 ＣＴ三维重建技术在颅颌面外科的适应症和应用价值。方法采用美国Ｉｍａｔｒｏｎ公司的电子束 ＣＴ（ｅｌｅｃｔｒｏｎ ｂｅａｍ ＣＴ，以下简称 ＥＢＣＴ） Ｃ－１５０，对 ７６例严重颅颌面病人实行薄层ＣＴ容积扫描。将所获 ＣＴ图象经数字接口传至加拿大 ＩＳＧ公司生产的 Ａｌｌｅｇｒｏ工作站进行三维重建。结果ＥＢＣＴ成像技术能立体的、详尽和精确的显示机体组织三维解剖结构极其相互关系。其再现畸形或病体模型的程度可以达到近乎解剖学的精度，为准确了解和掌握病情并制定合理的手术治疗计划提供了极为重要的依据，提高了手术治疗效果。结论 ＥＢＣＴ三维重建技术是现代颅颌面外科最主要的诊断方法之一并具有重要的临床应用价值。

Successful execution of a surgical treatment necessitates knowledge of the relevant anatomy, physiology, and pathology, as well as the technical specifics of the operation. At this time, the Cranio-maxillo-facial three-dimensional reconstruction can display bone change and relationship with adjacent smicthe, which is very useful for clinical assistance examination and more favorable and more accurate for establishing surgical operation planning. Since 1996, 76 patients have undergone this technique at the Service of Plastic and Cranio-maxillo-facial surgery in Beijing. We adapted our clinical results to four main indications : 1. Congeltitally cranio-maxillo-facial deformity; 2. Cranio-maxillo-facial trauma or post-traumatic reconstructive Surgery; 3. Cranio-maxillo-facial tumors surgery and 4. Cranio-maxillo-facial esthetic surgery. Tile indication of using the three-dimensional electron beam CT reconstruction technique in Cranio-maxillo-facial surgery with these managements is discussed and some cases of clinic are demonstrated.
