简介:AbstractMandibular condylar fractures are among the most common facial fractures and some of the most difficult to manage. Opinions about the management of mandibular condylar fractures differ among surgeons. With the implementation of new technology, an increased understanding of fracture management, and better functional and morphological outcomes reported in the literature, open reduction and internal fixation is becoming many surgeons’ preferred choice for the treatment of condylar fractures. Because surgical treatment of such fractures is complex, certain factors must be considered to achieve satisfactory outcomes. In this article, we summarise six key points in the management of mandibular condylar fractures: virtual evaluation of condylar fracture, a suitable surgical approach, good reduction, stable internal fixation, repair of the articular disc, and restoration of the mandibular arch width. We believe that these points will help to improve the prognosis of mandibular condyle fractures.

简介:从1998年起,福建日报社建立并逐步完善了采编网络系统,采编出版已实现了网络数字化,采写、编辑、传稿、审改、排印全由电脑网络数字传送。2001年建立了信息存储系统及网络备份系统(用大容量磁带库作为备份设备),实现了福建日报版面等电子资料的保存备份、检索查询。2002年8月25日,福建日报成立了报业集团,形成了以《福建日报》为龙头的六报一刊的格局。根据报业改革及信息技术的发展,报社的网络设备将进行技术改造,针对数码相机的广泛应用,计划建立新闻图片库。继财务、广告管理系统运用之后,2002年行政经营部门已全面纳入集团信息网,准备建设自动化办公系统,档案信息载体随之也将发生革命性的变化。这些变化要求档案工作者必须紧紧跟随报业的发展加快档案信息化进程。
