To describe the clinical and radiological characteristics, and surgical findings of traumatic bone cysts.
A retrospective observational study was made of 21 traumatic bone cysts. The diagnosis was based on the anamnesis, clinical exploration, and complementary tests. Panoramic and periapical X-rays were obtained in all cases, together with computed tomography as decided by the surgeon. A descriptive statistical analysis was made of the study variables using the SPSS v12.0 for Windows.
There was a clear female predominance (14:7). The mean age was 26.5 years (range 8-45 years). The cysts in all cases constituted casual findings during routine radiological exploration. In those cases where computed tomographic images were available, preservation of the vestibular and lingual cortical layers was observed. Five of the 21 patients (23.8%) reported a clear antecedent of traumatism in the affected zone. All the lesions were subjected to surgery, and the cavities were found to be vacant in 90.5% of the cases. In only two patients were vascular contents seen within the cavity. Two of the patients presented postoperative paresthesia of the inferior dental nerve that subsided within two weeks. The 19 patients in whom adequate postoperative follow-up proved possible all showed complete bone healing.
Traumatic bone cysts were a casual finding. During the surgery, most cases showed to be vacant cavity without an ephitelial lining. Careful curettage of the lesion favors progressive bone regeneration, offering a good prognosis and an almost negligible relapse rate. Other treatment options only would be justified in cases of relapse.
描述创伤性骨囊肿的临床、影像学特征及手术所见。
对21例创伤性骨囊肿进行回顾性观察研究。诊断基于病史、临床检查及辅助检查。所有病例均拍摄全景片和根尖片，外科医生根据情况决定是否进行计算机断层扫描。使用Windows版SPSS v12.0对研究变量进行描述性统计分析。
女性明显居多（14例：7例）。平均年龄为26.5岁（范围8 - 45岁）。所有病例中的囊肿均在常规影像学检查时偶然发现。在有计算机断层扫描图像的病例中，可见前庭和舌侧皮质层保存完好。21例患者中有5例（23.8%）报告在患区有明确的创伤史。所有病变均接受了手术，90.5%的病例发现腔内为空的。仅2例患者腔内可见血管内容物。2例患者术后出现下牙槽神经感觉异常，两周内缓解。19例患者术后进行了充分随访，均显示骨完全愈合。
创伤性骨囊肿为偶然发现。手术中，多数病例显示为无上皮衬里的空腔。仔细刮除病变有利于骨的逐步再生，预后良好，复发率几乎可忽略不计。仅在复发病例中才有理由采用其他治疗方案。
