Abstract

The reconstruction in case of large nasal defects, especially affecting the cartilaginous portion, is a surgical and aesthetic challenge. The result has to fulfill functional and aesthetic aspects concerning shape, texture, and nasal breathing, which requires accurate reproduction of nasal lining, support, and coverage. Here, we describe nasal reconstruction in a 36-year-old woman after near-total nasal resection due to a malignant peripheral nerve sheath tumor in the glabellar and nasal regions. After tumor resection, the cartilaginous and bone structures were reconstructed using a dynamic titanium mesh, which was precontoured on a three-dimensional-print model of the preoperative situation. Soft tissue defects were covered as a 2-stage procedure using a Converse scalp flap. We achieved an adequate long-term functional and aesthetic and oncological result. Titanium mesh in combination with Converse flap proved to be an alternative in extensive composite midfacial defects.

摘要

对于大面积鼻缺损的重建,尤其是影响软骨部分的缺损,是一项外科手术和美学上的挑战。结果必须在形状、质地和鼻呼吸方面满足功能和美学要求,这需要精确再现鼻内衬、支撑结构和覆盖物。在此,我们描述了一名36岁女性因眉间和鼻区恶性周围神经鞘瘤行近全鼻切除术后的鼻重建情况。肿瘤切除后,使用动态钛网重建软骨和骨结构,该钛网在术前情况的三维打印模型上预先塑形。软组织缺损分两期使用康弗斯头皮瓣覆盖。我们取得了良好的长期功能、美学和肿瘤学效果。钛网联合康弗斯皮瓣被证明是广泛复合性面中部缺损的一种替代方法。
