Distraction osteogenesis is a new and reliable technique for lengthening of hard and soft tissue in cranio-maxillofacial surgery. Since its first applications, X-rays were often the preferred diagnostic method to monitor this treatment. Apart from adding an additional radiation dose, analysis cannot detect and follow the osteogenic process in the distraction gap on the one hand, nor can it evaluate the soft tissue around the distracted area. In this paper, the authors report their experience with B-scan imaging to control mandibular distraction and to overcome the shortcomings of X-rays analysis.
Comparison of B-scanning with the traditional X-ray methods was performed in 12 patients.
B-scan evaluation appeared to be a precise technique in monitoring the different phases of distraction. It is easy to repeat whenever necessary. Early and late complications of soft tissue healing, movements of the bone segment, as well as the osteogenesis were easily detectable.
In the authors' opinion B-scan evaluation can play an important role in monitoring distraction osteogenesis.
牵张成骨术是颅颌面外科中用于软硬组织延长的一种新型可靠技术。自首次应用以来，X射线常是监测该治疗的首选诊断方法。一方面，除了增加额外的辐射剂量外，X射线分析无法检测和追踪牵张间隙中的成骨过程，也无法评估牵张区域周围的软组织。在本文中，作者报告了他们使用B超成像控制下颌骨牵张并克服X射线分析缺点的经验。
对12例患者进行了B超检查与传统X射线方法的比较。
B超评估似乎是监测牵张不同阶段的一种精确技术。必要时可轻松重复检查。软组织愈合的早期和晚期并发症、骨段移动以及成骨情况都易于检测。
作者认为，B超评估在监测牵张成骨术中可发挥重要作用。
