Liposarcoma is considered one of the most frequently occurring tumors of the soft tissues, representing 17% to 30% of all mesenchymal cell tumors. It is less common in the head and neck representing <10% of tumors in this region. The reconstruction of defects derived from resection of these tumors presents a surgical challenge. New three-dimensional digital technologies allow more exact surgery, cause less morbidity, and achieve adequate aesthetic outcomes.
The aim of this article was to describe the complex reconstruction of a defect caused by the resection of a liposarcoma in the temporal region.
Three-dimensional technology allowed patient planning and a reconstruction that was as exact as possible. A made-to-measure polymethyl methacrylate prosthesis was used to correct the defect in the zygomatic arch. The temporal fossa was covered with a standard porous polyethylene prosthesis.
Satisfactory esthetic and functional results were achieved using three-dimensional digital technology for treatment planning and to fabricate a made-to-measure polyethylene prosthesis and surgical guide.
脂肪肉瘤被认为是最常见的软组织肿瘤之一，占所有间充质细胞瘤的17%至30%。它在头颈部较少见，占该区域肿瘤的比例不到10%。这些肿瘤切除后缺损的重建是一项手术挑战。新的三维数字技术能实现更精确的手术，降低发病率，并取得良好的美学效果。
本文旨在描述颞区脂肪肉瘤切除术后缺损的复杂重建。
三维技术有助于患者规划和尽可能精确的重建。使用定制的聚甲基丙烯酸甲酯假体修复颧弓缺损。颞窝用标准的多孔聚乙烯假体覆盖。
使用三维数字技术进行治疗规划并制作定制的聚乙烯假体和手术导板，取得了满意的美学和功能效果。
