Little attention has been directed towards reconstruction of the mandibular condyles in adult patients with rheumatoid arthritis, other than with allogenic implants which are now known to cause serious complications. There is a relatively high incidence of condylar erosion and breakdown in rheumatoid arthritis, often leading to anterior open bite and retrognathia. Costochondral grafting does not appear to have been considered as a logical option for reconstruction, despite its high success rate in many other situations. A case is described of rapid bilateral condylar destruction occurring in a young woman with rheumatoid arthritis, leading to anterior open bite. Reconstruction was undertaken using bilateral costochondral grafts, giving an excellent clinical result which has been maintained over the follow-up period of two-and-a-half years. Radiologically complete healing of severe glenoid fossa erosion has taken place.
除了同种异体植入物（现已发现会引发严重并发症）外，针对成年类风湿性关节炎患者下颌髁突的重建关注甚少。类风湿性关节炎中髁突侵蚀和破坏的发生率相对较高，常导致前牙开合和下颌后缩。尽管肋软骨移植在许多其他情况下成功率很高，但似乎并未被视为重建的合理选择。本文描述了一名患有类风湿性关节炎的年轻女性双侧髁突迅速破坏，导致前牙开合的病例。采用双侧肋软骨移植进行重建，临床效果极佳，在两年半的随访期内得以维持。放射学检查显示严重的关节窝侵蚀已完全愈合。
