Nonsurgical prosthetic interventions are often proposed after repeated grafts have failed to restore irradiated facial defects. This report describes a facial prosthetic reconstruction following ablative surgery for a sizable facial tumor by using a novel custom-made magnet-bearing substructure, which connected with an exposed part of the mandibular reconstruction plate. The defect involved the entire left lower part of the face and angle of the mentum. This reconstructive technique, together with an added surface texture with hair-like silicone strands, effectively addressed the cosmetic needs of the patient. Magnetic anchorage to an exposed reconstruction plate could be considered an option for retaining facial prostheses. The biomechanical aspects of loading and retention should be addressed before considering this prosthetic option.
非手术性假体干预措施通常在多次移植未能修复放射性面部缺陷后提出。本报告描述了一例大的面部肿瘤切除术后,采用新型定制带磁体的子结构,连接下颌骨重建板的暴露部分,对面部假体进行重建。该缺损累及整个左下面部和下颌角。这种重建技术,加上添加具有毛发状硅酮线的表面纹理,有效地满足了患者的美容需求。磁体固定于暴露的重建板可被视为保留面部假体的一种选择。在考虑这种修复体选择之前,应解决加载和保留的生物力学方面问题。
