Scapula tip flaps have been introduced in the literature as an ideal surgical treatment option for large defects in the horizontal plane of the maxilla. This article aims to present a unique step by step protocol for a near total maxillectomy with a pterygoid bone resection and consecutive microvascular reconstruction with a harvested scapula tip flap. The protocol includes immediate placement of extra-short implants in donor bone with the aid of Virtual Surgical Planning (VSP), and an in-house 3D printing of medical 3D models and surgical guides. So far, there has been no presented surgical technique combining immediate implant placement in the scapula region with simultaneous microvascular repair. This technique allows: tumour resection; flap harvesting; extra-short implant placements and reconstruction to be performed in one simultaneous procedure. The technique is presented with illustrations, VSP (presented on videos), radiographs, and surgical findings. We discovered that this refinement of the scapula tip surgery has enabled reconstructive procedures to be performed at the same time as implant placements, providing expedited functional and aesthetic outcomes in selected cases. Moreover, modification of the surgical technique could enhance the competence of the oropharyngeal edge. In conclusion, this new surgical protocol utilizing VSP, 3D models and simultaneous extra-short implant placement provides indispensable advantages for such a complicated surgical procedures, while significantly shortening the duration of surgery.
肩胛尖皮瓣在文献中已被介绍为上颌骨水平面大缺损的理想手术治疗选择。本文旨在介绍一种独特的逐步方案,用于进行翼状骨切除的近全上颌骨切除术,并随后用切取的肩胛尖皮瓣进行微血管重建。该方案包括借助虚拟手术规划(VSP)在供骨中立即植入超短种植体,以及内部制作医学3D模型和手术导板的3D打印。到目前为止,尚未有将肩胛区立即植入种植体与同时进行微血管修复相结合的手术技术。该技术允许:在一个同步手术中进行肿瘤切除、皮瓣切取、超短种植体植入和重建。本文通过插图、VSP(视频展示)、X线片和手术结果展示了该技术。我们发现,这种肩胛尖手术的改进使得重建手术能够与种植体植入同时进行,在特定病例中提供了快速的功能和美学效果。此外,手术技术的改进可以提高口咽边缘的功能。总之,这种利用VSP、3D模型和同时植入超短种植体的新手术方案为如此复杂的手术提供了不可或缺的优势,同时显著缩短了手术时间。
