髁突骨软骨瘤的诊治及影像学分析
|
Abstract:
摘要 目的: 自2010~2017年回顾性研究6例下颌骨髁突骨软骨瘤病例,涉及患者年龄、性别、病理学表现、治疗方式和复发情况。方法: 研究选取X线、螺旋CT或核磁共振扫描符合下颌骨髁突骨软骨瘤病例。对收集的数据进行记录和分析。结果: 研究中包含1名男性患者和5名女性患者,病变累及左右侧比例为5∶1。年龄34~68岁(平均年龄54.6岁)。6例患者中有4例病变位于髁突上内侧。5名患者选择髁突高位切除术,1例选择髁突全切除术。所有病例采用耳前及耳颞联合入路。随访周期为1~7年,没有发现复发病例。结论: 渐进性面部不对称是髁突骨软骨瘤的显著特征。髁突高位切除术和髁突全切除术都可作为治疗选择。当肿瘤发生于髁突上方或上内侧,下颌骨偏斜不明显,仅需要髁突高位切除即可,患者面部不对称可在术后逐步恢复;如果下颌骨偏斜显著,导致面型偏斜或咬合错乱,则需要实施髁突全切除术及正颌手术
