Osteomas are benign osteogenic tumors composed of mature compact or cancellous bone and are characterized by slow, painless growth. A peripheral osteoma located in the mandibular notch is extremely rare. Here, we describe the case of a 38-year-old woman with an active peripheral osteoma in the mandibular notch for long-term follow up. Surgical resection of the lesion was performed, which resulted in the improvement of the mandibular function and temporomandibular dysfunction. This is the first report of resection surgery after confirming the activity of peripheral osteoma by bone scintigraphy. Creating a three-dimensional model of the mandible promises an accurate surgical plan.
骨瘤是由成熟的密质骨或松质骨组成的良性成骨性肿瘤，其特点是生长缓慢、无痛。位于下颌切迹的外周性骨瘤极为罕见。在此，我们描述了一例38岁女性，其下颌切迹处有一活动性外周性骨瘤，并进行了长期随访。对该病变进行了手术切除，术后下颌功能及颞下颌关节功能障碍得到改善。这是首例通过骨闪烁显像确认外周性骨瘤的活动性后进行切除手术的报告。构建下颌骨三维模型有助于制定精确的手术方案。
