Capsular contracture is a rare but serious complication of silicone implant-based augmentation rhinoplasty. When severe, the contracture can affect all layers of the nose, causing significant scarring and disfigurement. There is currently no standardized method of evaluating contracted noses and a paucity of literature on the treatment of severe contracture. Therefore, this study aimed to establish a comprehensive grading system and treatment approach for patients with nasal contracture secondary to silicone implant-based rhinoplasty.
We conducted a retrospective analysis on patients who presented with nasal contracture from 2012 to 2021. All preoperative photographs were evaluated by two plastic surgeons, twice at 1-month intervals. The proposed grading system comprised: normal (grade I), mild contracture with detectable implant (grade II), moderate contracture with skin thinning (grade III), severe contracture with short nose deformity (grade IV), and destructive contracture with scarring of the dorsal skin (grade Va), or columella deficiency (grade Vb). Inter- and intraobserver agreement was assessed using the kappa value to determine the reliability of the system.
Based on 87 patients, interobserver agreement was substantial for both evaluation time points (k = 0.701 and 0.723). Intraobserver agreement was excellent for evaluator 1 (k = 0.822) and substantial for evaluator 2 (k = 0.699).
Using this grading system, we propose a graduated treatment algorithm for contracted noses. Most notable is our use of radial forearm free or forehead flaps to reconstruct the columella in grade Vb patients. By combining reconstructive and aesthetic principles, this treatment approach provides an effective and elegant solution for the management of the severely contracted nose.

包膜挛缩是硅胶假体隆颏术后罕见但严重的并发症。严重时,挛缩可累及鼻部所有层次,导致显著的瘢痕和畸形。目前尚无评估挛缩鼻的标准化方法,且严重挛缩的治疗方法文献也较少。因此,本研究旨在建立一个全面的分级系统和针对硅胶假体隆颏术后发生鼻部挛缩的患者的治疗方法。
我们对 2012 年至 2021 年期间因硅胶假体隆颏术后出现鼻部挛缩的患者进行了回顾性分析。所有术前照片均由两名整形外科医生评估,两次评估间隔 1 个月。所提出的分级系统包括:正常(I 级)、可检测到假体的轻度挛缩(II 级)、皮肤变薄的中度挛缩(III 级)、短鼻畸形的严重挛缩(IV 级)、以及伴有背侧皮肤瘢痕(Va 级)或鼻中隔缺损(Vb 级)的破坏性挛缩。采用 Kappa 值评估系统的可靠性,评估组内和组间的一致性。
基于 87 例患者,两次评估时组间一致性均为中等(k 值分别为 0.701 和 0.723)。评估员 1 的组内一致性为极好(k 值为 0.822),评估员 2 的组内一致性为显著(k 值为 0.699)。
使用该分级系统,我们提出了一种针对挛缩鼻的分级治疗算法。值得注意的是,我们在 Vb 级患者中使用游离或额部皮瓣重建鼻中隔。通过结合重建和美学原则,这种治疗方法为严重挛缩鼻的处理提供了有效而优雅的解决方案。
