The etiology and pathogenesis of traumatic bone cyst are still far from being conclusively established with multiple theories, names, and forms of management being proposed and used. The rarity of these lesions in the older age groups suggests that self-healing can occur. This article presents two well-documented cases of what clinically and radiographically were consistent with so-called "traumatic bone cyst" of the mandible, which have appeared to heal without surgical intervention, thus providing additional information to our understanding of the biologic nature of this entity. Case 1 involved a 14-year-old boy with a lesion of the anterior left mandible that was monitored for 7 years and 5 months. Case 2 involved a 19-year-old female patient with a lesion of the right mandible that was monitored for 2 years and 9 months. In both cases, intraosseous biopsy or other surgical procedures were not undertaken. By the time both patients approached age 22, their lesions had resolved and the trabecular bone pattern radiographically approached normal.
创伤性骨囊肿的病因和发病机制尚未完全明确，目前有多种理论、名称及治疗方式被提出和应用。这些病变在老年人群中较为罕见，提示其可能会自愈。本文介绍两例记录详实的病例，临床上和影像学表现均符合下颌骨所谓的“创伤性骨囊肿”，且未经手术干预似乎已自愈，从而为我们理解该疾病的生物学特性提供了更多信息。病例1为一名14岁男孩，左下颌前部有一病变，被监测了7年零5个月。病例2为一名19岁女性患者，右下颌有一病变，被监测了2年零9个月。两例均未进行骨内活检或其他外科手术。当两名患者接近22岁时，其病变均已消退，影像学上小梁骨形态接近正常。
