Whereas rhinoplasty with a reduction of the dorsum and modification of the tip is a common procedure among Caucasians, augmentation of the dorsum remains a challenge in Asians. Choice of the ideal grafting material for dorsal augmentation is a matter of preference and remains under discussion. Autologous and alloplastic materials have their advantages and disadvantages. We report our experiences of the extrusion of alloplastic materials and their management. We report of 18 patients, who had rhinoplasty in the past for dorsal augmentation with alloplastic material. Augmentation rhinoplasty was performed in Asia ( = 15) and Germany ( = 3). All cases showed recurrent signs of foreign body infection and/or partial extrusion and therefore underwent revision surgery in our centers. Once all patients had been successfully treated with antibiotics, we performed a one-stage revision rhinoplasty with explantation of the alloplastic material and subsequent reconstruction with autologous rib cartilage. The nasal dorsum was augmented with either solid rib cartilage grafts, diced cartilage in fascia, or free diced cartilage in platelet-rich fibrin. All patients received pre-, peri-, and postoperative antibiotics. The outcome was screened via clinical examination, ultrasound examination pre- and postoperatively, two-dimensional/three-dimensional (3D) imaging, and magnetic resonance imaging scans.Alloplastic augmentation of the nasal dorsum runs the risk of foreign body reaction, recurrent infections, uncontrolled scarring, and unsatisfying long-term results. We have obtained a series of aesthetically and functionally satisfying results after single-stage revision surgery with autologous cartilage and demonstrate a variety of novel postoperative screening tools including 3D imaging and high-frequency ultrasound.

虽然白人中常见的鼻部整形术是通过减少背部和修改鼻尖来实现的,但亚洲人增加背部的难度仍然很大。选择理想的用于增加背部的移植物材料是一个偏好问题,仍在讨论中。自体和异体材料都有其优缺点。我们报告了我们对异体材料挤出及其管理的经验。我们报告了 18 例过去因使用异体材料进行背部增加而接受过鼻整形术的患者。在亚洲( = 15)和德国( = 3)进行了增强型鼻整形术。所有病例均显示出复发性异物感染和/或部分挤出的迹象,因此在我们的中心接受了修复手术。一旦所有患者都成功接受了抗生素治疗,我们就会进行一期修复性鼻整形术,取出异体材料,并随后使用自体肋软骨进行重建。用固体肋软骨移植物、筋膜内切碎软骨或富含血小板的纤维蛋白中的游离切碎软骨来增加鼻背。所有患者均接受术前、术中和术后抗生素治疗。通过临床检查、术前和术后超声检查、二维/三维(3D)成像和磁共振成像扫描来筛选结果。异体鼻部增加存在异物反应、复发性感染、不受控制的瘢痕和不满意的长期结果的风险。我们通过自体软骨的单阶段修复手术获得了一系列美学和功能上令人满意的结果,并展示了多种新的术后筛查工具,包括 3D 成像和高频超声。证据水平:无。
