Surgical refinement of the wide nasal tip is challenging. Achieving an attractive, slender, and functional tip complex without destabilizing the lower nasal sidewall or deforming the contracture-prone alar rim is a formidable task. Excisional refinement techniques that rely upon incremental weakening of wide lower lateral cartilages (LLC) often destabilize the tip complex and distort tip contour. Initial destabilization of the LLC is usually further exacerbated by "shrink-wrap" contracture, which often leads to progressive cephalic retraction of the alar margin. The result is a misshapen tip complex accentuated by a conspicuous and highly objectionable nostril deformity that is often very difficult to treat. The "articulated" alar rim graft (AARG) is a modification of the conventional rim graft that improves treatment of secondary alar rim deformities, including postsurgical alar retraction (PSAR). Unlike the conventional alar rim graft, the AARG is sutured to the underlying tip complex to provide direct stationary support to the alar margin, thereby enhancing graft efficacy. When used in conjunction with a well-designed septal extension graft (SEG) to stabilize the central tip complex, lateral crural tensioning (LCT) to tighten the lower nasal sidewalls and minimize soft-tissue laxity, and lysis of scar adhesions to unfurl the retracted and scarred nasal lining, the AARG can eliminate PSAR in a majority of patients. The AARG is also highly effective for prophylaxis against alar retraction and in the treatment of most other contour abnormalities involving the alar margin. Moreover, the AARG requires comparatively little graft material, and complications are rare. We present a retrospective series of 47 consecutive patients treated with the triad of AARG, SEG, and LCT for prophylaxis and/or treatment of alar rim deformities. Outcomes were favorable in nearly all patients, and no complications were observed. We conclude the AARG is a simple and effective method for avoiding and correcting most alar rim deformities.
宽鼻尖的手术精细化具有挑战性。在不破坏鼻下侧壁稳定性或不使易挛缩的鼻翼缘变形的情况下,实现一个美观、纤细且功能良好的鼻尖复合体是一项艰巨的任务。依靠逐步削弱宽的下外侧软骨(LLC)的切除精细化技术常常会破坏鼻尖复合体的稳定性并扭曲鼻尖轮廓。LLC的初始不稳定通常会因“收缩包裹”挛缩而进一步加剧,这往往会导致鼻翼缘逐渐向头侧回缩。结果是鼻尖复合体畸形,伴有明显且非常令人反感的鼻孔畸形,这种畸形通常很难治疗。“铰接式”鼻翼缘移植片(AARG)是对传统鼻翼缘移植片的一种改良,可改善对继发性鼻翼缘畸形的治疗,包括术后鼻翼回缩(PSAR)。与传统鼻翼缘移植片不同,AARG缝合至下方的鼻尖复合体,为鼻翼缘提供直接的固定支撑,从而提高移植片的效果。当与精心设计的鼻中隔延伸移植片(SEG)联合使用以稳定中央鼻尖复合体、进行外侧脚张紧(LCT)以收紧鼻下侧壁并使软组织松弛最小化,以及松解瘢痕粘连以使回缩和瘢痕化的鼻内衬里展开时,AARG可在大多数患者中消除PSAR。AARG在预防鼻翼回缩以及治疗大多数其他涉及鼻翼缘的轮廓异常方面也非常有效。此外,AARG所需的移植材料相对较少,且并发症罕见。我们回顾性分析了连续47例接受AARG、SEG和LCT三联疗法预防和/或治疗鼻翼缘畸形的患者。几乎所有患者的结果都很理想,且未观察到并发症。我们得出结论,AARG是一种避免和纠正大多数鼻翼缘畸形的简单有效的方法。
