To describe vertical distraction osteogenesis of a scapular flap and removable lip support for oral rehabilitation after surgical creation of an ablative defect of the mandible.
A 70-year-old man who was diagnosed with squamous cell carcinoma of the left lower gingiva underwent segmental mandibulectomy for tumor ablation and reconstruction with a scapular bone flap. To augment bone height of this flap, vertical distraction osteogenesis was performed. After denture fabrication, a removable lip support was placed between the implant-supported denture and the lower lip.
The bone height of the scapular bone flap increased by 9 mm. Implants with adequate length could be placed in the distracted bone. The lip support was effective. Two years after masticatory loading, the implants remained stable.
Vertical distraction osteogenesis of the scapular bone flap was suitable to facilitate postoperative functional and esthetic restoration after tumor resection. A removable lip support was also useful as a supplementary tool for oral rehabilitation.
描述肩胛骨瓣垂直牵张成骨及可摘唇支撑物在手术造成下颌骨缺损后口腔修复中的应用。
一名70岁男性被诊断为左下牙龈鳞状细胞癌,接受了节段性下颌骨切除术以切除肿瘤并用肩胛骨骨瓣进行重建。为增加该骨瓣的骨高度,进行了垂直牵张成骨。制作义齿后,在种植体支持的义齿和下唇之间放置了一个可摘唇支撑物。
肩胛骨骨瓣的骨高度增加了9毫米。可以在牵张后的骨中植入足够长度的种植体。唇支撑物效果良好。咀嚼负荷两年后,种植体保持稳定。
肩胛骨瓣垂直牵张成骨适用于促进术后功能和美学恢复。可摘唇支撑物作为口腔修复的辅助工具也很有用。
