UNASSIGNED: We present a case of a DGCT in a 12-year-old boy with wide infiltration of the mandible and the TMJ. A two-staged reconstructive approach was performed. Upon primary surgery, tumour-free margins were obtained and mandibular anatomy was restored using an iliac crest graft and an alloplastic condyle implant for temporary TMJ reconstruction. In a second step 5 months later, having received a customized TMJ prosthesis consisting of a fossa and a condyle component, the TMJ was completely replaced for definitive reconstruction.
UNASSIGNED: A customized TMJ prosthesis could be a solution for reconstruction of the TMJ in children. However, the further course with respect to growth disturbances must be evaluated upon short-term follow-ups and might require additional corrective interventions.
■我们介绍了一个12岁男孩的DGCT病例,下颌骨和TMJ广泛浸润。进行了两阶段的重建方法。在初次手术时,获得了无瘤边缘,并使用a骨移植物和同种异体髁植入物修复了下颌骨解剖结构,以进行临时TMJ重建。在5个月后的第二步中,收到了由窝和髁组件组成的定制TMJ假体,TMJ被完全替换为最终的重建。
■定制的TMJ假体可能是儿童TMJ重建的解决方案。然而,关于生长障碍的进一步过程必须在短期随访中进行评估,并且可能需要额外的纠正干预措施。
