This paper describes a case of vertical distraction osteogenesis of a free vascularized osteocutaneous scapular flap in the reconstructed mandible before implant therapy. The patient was a 67-year-old woman with squamous cell carcinoma of the right lower gingiva. She underwent segmental mandibulectomy for tumor ablation and reconstruction with an osteocutaneous scapular flap. The distraction protocol, clinical course and implant therapy are presented. Through this procedure, the bone height of the scapular graft increased by 10mm. Implants with adequate length could be placed in the distracted area. Two years after masticatory loading, the condition of these implants was stable. Vertical distraction osteogenesis of the scapular flap was considered effective when performed before implant therapy, to facilitate postoperative functional and esthetic restoration after tumor resection.
本文描述了1例在种植治疗前,对重建下颌骨中的游离血管化肩胛皮瓣进行垂直骨牵张成骨的病例。患者为一名67岁女性,患有右下牙龈鳞状细胞癌。她接受了节段性下颌骨切除术以切除肿瘤,并采用肩胛皮瓣进行重建。文中介绍了牵张方案、临床过程及种植治疗情况。通过该手术,肩胛移植骨的骨高度增加了10毫米。可以在牵张区域植入长度合适的种植体。咀嚼负荷两年后,这些种植体的状况稳定。肩胛皮瓣垂直骨牵张成骨在种植治疗前进行时,被认为对促进肿瘤切除术后的功能和美学恢复有效。
