目的：儿童下颌骨病变往往是良性的，这允许一个保守的手术方法来管理。两种最常见的方法来重建后天下颌骨缺损的青少年是血管化和非血管化骨瓣或移植。第三种，不太常用的治疗选择，经常在世界上的发展中地区使用，一些西方中心正在考虑作为他们的治疗算法的一部分是自发性骨再生。本研究报告作者的经验，自发性骨形成的年轻下颌骨切除。它还试图量化自发性骨再生和老化的osteocentric periosteum.Patients和方法之间的任何关系：这是一项回顾性研究的基础上，从记录整理的口腔颌面外科部门从2个大专院校的连续数据。符合条件的患者年龄不超过18岁，患有良性下颌骨肿瘤。手术方法为下颌骨切除、骨膜下分离和颌间固定。再生骨评估是通过临床检查和定期的曲面断层片。结果：16例下颌骨病变被认为是在2个机构，其中8个符合纳入标准。平均年龄为10.75岁。主要病理为单囊型成釉细胞瘤。所有病例均表现出自发性骨再生，2例表现出“不完全”的骨regeneration.Conclusion：立即重建可以延迟，让自发性骨再生的缺陷，在年轻患者。在没有再生的情况下，可以考虑进行二次重建。虽然文献报道年轻患者的骨再生比成年人多，但儿童和青少年时期年龄的增加可能不一定表明骨膜骨再生潜力的降低。(C)2016年美国口腔颌面外科医师协会
Purpose: Childhood mandibular lesions are frequently benign; this allows for a conservative surgical approach to their management. Two of the most common approaches for reconstruction of acquired mandibular defects in adolescents are vascularized and nonvascularized osseous flaps or grafts. A third, less commonly used treatment option often used in developing parts of the world that some Western centers are considering as part of their treatment algorithm is spontaneous bone regeneration. This study reports on the authors' experiences with spontaneous bone formation of the resected young mandible. It also attempts to quantify any relation between spontaneous bone regeneration and an aging osteocompetent periosteum.Patients and Methods: This was a retrospective study based on consecutive data collated from records of the oral and maxillofacial surgery departments from 2 tertiary institutions. Eligible patients were no older than 18 years and had benign mandibular neoplasms. The surgical procedure was mandibulectomy with subperiosteal dissection and intermaxillary fixation. Regenerated bone evaluation was by clinical examination and periodic panoramic radiographs.Results: Sixteen consecutive cases with mandibular lesions were seen at the 2 institutions, 8 of which met the inclusion criteria. The average age was 10.75 years. The predominant pathology was unicystic ameloblastoma. All cases exhibited spontaneous bone regeneration, with 2 cases exhibiting "incomplete" bone regeneration.Conclusion: Immediate reconstruction can be delayed to allow for spontaneous bone regeneration of defects in young patients. In the absence of regeneration, secondary reconstruction can be considered. Although the literature reports more young patients with bone regeneration than adults, increasing age during childhood and adolescence might not necessarily indicate a decrease in periosteal bone-regenerating potential.
