计算机合成颞下颌关节镜全景图像临床应用研究

Clinical Application of Computed Arthroscope of the Temporomandibular Joint

目的 :评价计算机合成颞下颌关节镜全景图像的临床应用价值。方法 :32例关节镜手术经计算机辅助系统合成关节镜全景图像 ;其中 ,10例进行术后即刻关节全景图像的合成 ,以评价术后的手术效果。结果 :所有全景关节镜图像均全面显示了关节腔整体形态、多种病理表现和关节各面之间的关系。结论 :该系统能提高关节镜综合诊断的能力 ,有利于促进颞下颌关节镜外科的发展、交流和推广。

Objective: The effect of clinical application on the computed arthroscope of the temporomandibular joint (TMJ) is evaluated. Methods: The single arthroscopic images were input into computer and memorized into magneto optical disk. With the help of Photoshop 5.0 in WINDOWS 95, the images were combined by technique of virtual process, adjusted by rotation of images, marginal blur, and chromatism correction to compound sagittal and/or coronal panoramic images of articular surfaces. According to different needs, the composite images can be printed with different printers. During the period from May 1998 to May 1999, the TMJ preoperative panoramic images were composed with computed arthroscope (CA) in the 32 joints. Of them, there were 12 joints with internal derangement (ID), 8 osteoarthrosis (OA), 8 adhesion, 2 disk perforation, and 2 synovial chondromatosis. The postoperative panoramic images were also made up to evaluate the surgical effects in 10 joints. Results: In all of 32 joints, the 32 panoramic arthroscopic images of upper cavities were composed. In addition, the images of lower cavities were composed in 2 OA and 1 perforation. The postoperative panoramic images were also made up in 4 OA, 4 adhesion, and 2 synovial chondromatosis. All of the above-mentioned images showed integrally the entire structure of articular cavity, intracapsular pathologic/surgical apperances, and the relationships among the different tissues or articular surfaces. Conclusion: The CA can enhance the comprehensive ability of diagnostic arthroscope, and help to exchange and spread the experiences of the TMJ arthroscopic surgery.
