Reconstruction of mandibular substance loss by a free flap is a widely used technique. This technique suffers from several disadvantages, including the presence of a second intervention site and a substantial frequency of complications. We have undertaken a custom-made 3-dimensional reconstruction (using computer-aided design and manufacturing) with prosthetic dental rehabilitation and esthetic improvement by lipomodeling of the face. A 50-year-old woman presented with a massive recurrence of an ameloblastoma of the right hemimandible. A cervical approach was used to resect the mandible well away from the tumor site. In light of her refusal to undergo reconstruction by a fibula free flap, reconstruction was performed using a custom-made porous titanium device with dental prosthetic rehabilitation, followed by lipomodeling of the face. The reconstruction was achieved without the occurrence of any complications. The implant-supported prosthetic dental implantation and the lipofilling resulted in functionally and esthetically satisfactory outcomes. Three-dimensional mandibular reconstruction with a custom-made porous titanium device and lipofilling yielded satisfactory results. Fitting of the dental prosthesis was undertaken at an early stage as it did not require osseointegration, although there was a need to overcome difficulties linked with the seal and the stability of the dental prosthesis and titanium support. The duration of patient follow-up was 18 months.
采用游离皮瓣修复下颌骨组织缺损是一种广泛应用的技术。该技术存在若干缺点,包括存在第二个手术部位以及并发症发生率较高。我们采用了定制的三维重建技术(利用计算机辅助设计和制造),并通过面部脂肪建模进行义齿修复和美学改善。一名50岁女性因右半侧下颌骨成釉细胞瘤大量复发前来就诊。采用颈部入路在远离肿瘤部位的地方切除下颌骨。鉴于她拒绝接受游离腓骨皮瓣重建,遂使用定制的多孔钛装置进行重建并进行义齿修复,随后对面部进行脂肪建模。重建过程未出现任何并发症。种植体支持的义齿植入和脂肪填充在功能和美学方面均取得了令人满意的效果。采用定制的多孔钛装置和脂肪填充进行三维下颌骨重建取得了满意的结果。由于义齿修复不需要骨整合,因此在早期就进行了义齿安装,不过需要克服与义齿及钛支架的密封和稳定性相关的困难。患者的随访期为18个月。
