Bisphosphonates are a class of agents used to treat osteoporosis and malignant bone metastases. Despite these benefits, osteonecrosis of the jaws has recently emerged as a significant complication in a subset of patients receiving these drugs. Based on a growing number of case reports and institutional reviews, bisphosphonate therapy may cause exposed and necrotic bone that is isolated to the jaw. This complication usually presents following simple dentoalveolar surgery and can cause a significant adverse effect on the quality of life for most patients. The pathogenesis for this complication appears to be related to the profound inhibition of osteoclast function and bone remodeling. This report will review the clinical signs and symptoms and risks associated with this new complication and provide a guideline for establishing a stage-specific diagnosis of BRONJ.
双膦酸盐是一类用于治疗骨质疏松症和恶性骨转移的药物。尽管有这些益处,但颌骨坏死最近已成为接受这些药物治疗的一部分患者的严重并发症。基于越来越多的病例报告和机构综述,双膦酸盐治疗可能导致局限于颌骨的暴露和坏死骨。这种并发症通常在简单的牙槽外科手术后出现,并且会对大多数患者的生活质量造成重大不利影响。这种并发症的发病机制似乎与破骨细胞功能和骨重塑的深度抑制有关。本报告将回顾与这种新并发症相关的临床体征、症状和风险,并提供建立颌骨坏死分期特异性诊断的指南。
