摘要:
目的 探讨多层螺旋CT三维重建在下颌骨骨折治疗中内固定材料长度选择及塑型的应用价值。方法 对5例下颌骨扫描病人进行三维重建,重建后测量拟行内固定的下颌骨长度,然后在下颌骨曲线上选择一些等距的点,分别测量这些点与曲线两端的距离,利用自制的曲线描绘工具等比例描绘出下颌骨的曲线。结果 全部病人三维重建去除软组织及其他骨骼后能多方位观察下颌骨。软件中的曲线测量工具准确量出了下颌骨的长度。测量下颌骨曲线上选定的各点与曲线两端的距离后,利用曲线描绘工具等比例绘出了下颌骨的生理曲线,最后准确选择了下颌骨内固定材料的长度并塑型。结论 通过多层螺旋CT三维重建并测量后,骨骼曲线描绘工具完全能精确绘出骨骼的生理曲线,最后可准确地对内固定材料进行长度选择与塑型。本方法可显著提高内固定材料与骨骼表面的贴附率,增加选材准确性,节省材料,缩短手术时间,提高手术疗效,减少对病人的副损伤。
Abstract:
Objective To investigate the value of multislice spiral CT (MSCT) scanning and three-dimensional reconstruction in selecting optimal length and shape of mandible internal fixation material. Methods Three-dimensional reconstruction of the mandible was performed in 5 cases by MSCT scanning and the length of the mandible for operation was measured. Some isometric points were chosen on the mandibular curve and the distance from these points to the two ends of the curve was measured to depict the mandibular curve using a self-designed skeletal curve-depicting software. The optimal length and shape of the material for internal fixation was then determined. Results After removal of the soft tissues and other irrelevant bones from the reconstructed three-dimensional mandible with clear view from any directions, the length of the mandible was accurately measured with the software. The physiological curve of the mandible was generated after determination of the distances from the chosen points on the mandibular curve and to the two ends of the curve for precise determination of the length and shape of the material for internal fixation. Conclusion Three-dimensional mandible reconstruction with MSCT and measurement facilitates the determination of the optimal length and shape of the internal fixation material to enhance the attachment between the material and the bone surface and consequently the therapeutic effects.
