Head and neck malignancies constitute a major cause of morbidity and mortality all over the world. Radiotherapy plays a pivotal role in the management of these tumours; however, it has associated complications, with mandibular osteoradionecrosis (ORN) being one of the gravest orofacial complications. Early diagnosis, extent evaluation, and detection of complications of ORN are imperative for instituting an appropriate management protocol. ORN can closely mimic tumour recurrence, the differentiation of which has obvious clinical implications. The purpose of the present review is to acquaint the radiologist with the imaging features of mandibular ORN and the ways to differentiate ORN from tumour recurrence.
头颈部恶性肿瘤是全世界发病率和死亡率的主要原因。放射治疗在这些肿瘤的治疗中起着关键作用;然而，它也有相关的并发症，其中下颌放射性骨坏死（ORN）是最严重的口腔颌面部并发症之一。早期诊断、充分评估和检测 ORN 的并发症对于制定适当的治疗方案至关重要。ORN 可能与肿瘤复发密切相似，这两者的鉴别具有明显的临床意义。本综述的目的是使放射科医生了解下颌 ORN 的影像学特征及其与肿瘤复发的鉴别方法。
