Small plate osteosynthesis is becoming increasingly popular in reconstruction following ablative surgery for oral malignancies. In those cases where postoperative radiotherapy is to be included in the treatment it has been suggested that these plates may cause problems such as dose enhancement and tumour shielding and should therefore be removed prior to the radiotherapy. A physical method is described to assess the anticipated radiation dose changes at the tissue/plate interface both behind and in front of the plate. As a result of this assessment certain recommendations are made.
小型接骨板骨合成术在口腔恶性肿瘤切除术后的重建中越来越受欢迎。在那些治疗中包括术后放疗的病例中，有人提出这些接骨板可能会导致诸如剂量增强和肿瘤屏蔽等问题，因此应在放疗前取出。本文描述了一种物理方法，用于评估接骨板前后组织/接骨板界面处预期的辐射剂量变化。根据这一评估结果，提出了一些建议。
