Abstract

Introduction: Maintaining nasal tip projection and rotation while preserving physiological mobility remains challenging in rhinoplasty.

Objectives and hypotheses: This study aimed to evaluate the clinical feasibility and biomechanical behavior of the columellolobular strut. We hypothesized that an angled configuration would demonstrate balanced mechanical behavior under load.

Study design: This was a retrospective observational case series (N = 115) supported by finite element modeling, conducted in accordance with STROBE guidelines.

Methods: Patients undergoing primary rhinoplasty between January 2021 and April 2024 were included. Finite element modeling assessed deformation and stress at 120, 150, and 180 degrees under standardized compressive loading. Clinical outcomes were evaluated descriptively.

Results: Stable nasal tip projection and columellar position were clinically observed during a mean follow-up of 32 months. Finite element analysis demonstrated reduced deformation and stress with decreasing angulation, with the 120 degrees configuration showing the most balanced response.

Conclusions: The columellolobular strut represents a biomechanically supported option for nasal tip stabilization while preserving controlled tip mobility.

小柱支撑：稳定鼻尖支撑的生物力学验证技术。

在鼻整形术中，保持鼻尖突出和旋转的同时保持生理活动能力仍然是一个挑战。目的与假设本研究旨在评估小叶小柱支架的临床可行性和生物力学行为。我们假设一个有角度的结构会在负载下表现出平衡的机械行为。研究设计：这是一个回顾性观察病例系列（N=115），由有限元建模支持，按照STROBE指南进行。方法选取于2021年1月至2024年4月接受鼻部整形手术的患者。在标准压缩载荷下，有限元模型评估了120°、150°和180°的变形和应力。对临床结果进行描述性评价。结果平均随访32个月，鼻尖和鼻小柱位置稳定。有限元分析表明，随着角度的减小，变形和应力减小，120°的配置显示出最平衡的响应。结论小叶小柱支撑是一种生物力学支持的鼻尖稳定选择，同时保持了鼻尖的可动性。

期刊介绍： Facial Plastic Surgery is a journal that publishes topic-specific issues covering areas of aesthetic and reconstructive plastic surgery as it relates to the head, neck, and face. The journal''s scope includes issues devoted to scar revision, periorbital and mid-face rejuvenation, facial trauma, facial implants, rhinoplasty, neck reconstruction, cleft palate, face lifts, as well as various other emerging minimally invasive procedures. Authors provide a global perspective on each topic, critically evaluate recent works in the field, and apply it to clinical practice.
