Nomogram model to predict postoperative infection after mandibular osteoradionecrosis surgery Zhonglong Liu1, Tianguo Dai1,2, Zhonghe Wang3, Zhiyuan Zhang1, Weiliu Qiu1 & Yue He1 Osteoradionecrosis of the mandible (ORNM) is one of the most dreaded complications of radiotherapy. The poor healing capacity of soft tissue after radiation may lead to surgical failure. The current study was designed to identify prognostic factors for postoperative infection (PPI) and propose corresponding prophylaxis and intervention protocols. A retrospective study was conducted concerning ORNM patients from 2000 to 2015. A risk-stratification score and nomogram model were established to predict the risk of PPI. A total of 257 patients were analyzed, and the total incidence of PPI was 23.3% (60/257). In multiple logistic regression analysis, radiation dose ⩾80 Gy (versus
