Periodontoid hypertrophic cicatrix resulting from trauma, as demonstrated by magnetic resonance (MR) imaging, is essentially the same as that seen in rheumatoid arthritis. Recent reports suggest that, in rheumatoid arthritis, occipitocervical fusion without transoral decompression of the pannus is adequate for resolution of this anterior lesion. A case of traumatic periodontoid cicatrix is presented in which posterior fusion resulted in reduction of the anterior mass lesion, clearly demonstrated by MR imaging. The etiology of periodontoid hypertrophic scarring, both traumatic and rheumatoid, is discussed in light of MR findings, and treatment implications are considered.
磁共振成像（MR）显示，创伤导致的齿突肥大性瘢痕与类风湿关节炎所见的瘢痕本质上相同。近期报告表明，在类风湿关节炎中，不进行经口减压清除血管翳的枕颈融合术足以解决这种前部病变。本文报告了一例创伤性齿突瘢痕病例，其中后路融合术使前部肿块病变缩小，MR成像清晰显示了这一点。结合MR表现讨论了创伤性和类风湿性齿突肥大性瘢痕形成的病因，并考虑了治疗意义。
