The researchers proposed a patient-specific mandible reconstruction planning method. This method uses the predicted bone union propensity as a core basis, aiming to improve the accuracy and applicability of surgical plans. The relevant research results were published in the arXiv cs.CV preprint on September 7, 2026.

Towards patient-specific optimization for mandibular reconstruction planning based on predicted bone-union propensity

OsteoOpt++ 系统通过贝叶斯优化方法,针对血管化骨移植中的供体 - 宿主非愈合问题,实现了基于预测骨愈合倾向的个性化下颌重建规划。该系统将术前 CT 转换为数字孪生,在六个临床可控变量下搜索最优方案。在通用病例中,相对于外科医生的几何计划,循环平均供体 - 下颌贴合度提升了多达 29 个百分点;在患者特定病例中,相对于术后第 5 天实施配置,提升幅度达 26 个百分点。敏感性分析显示,模型参数变化对贴合度目标的影响被限制在约 3% 至 4% 以内,且预测贴合度与第一年骨形成之间的 Dice 重叠率介于 70.1% 至 84.9%。这些结果支持 OsteoOpt++ 用于比较候选重建方案,其优化代码已开源。
