The septal extension graft is one of the most commonly used grafts in Asian tip plasty techniques. However, the septal extension graft usually induces a hard and immobile nasal tip. The purpose of this study was to evaluate the esthetic outcomes of the modified septal extension graft with M-shaped auricular cartilage by three-dimensional anthropometric analysis.
A total of 36 patients received augmentation rhinoplasty with M-shaped auricular cartilage as septal extension graft combined with silicone implant. Thirteen measurement items were evaluated using three-dimensional anthropometric techniques, and the preoperative and postoperative results were compared.
The majority of patients (91.7%) were satisfied with the postoperative nasal shape. No infection, gross absorption, graft exposure, implant exposure, or implant migration was observed. Compared with the preoperative value, the nasal length, nasal height, nasal depth, nasion height, columella width, nasolabial angle, nasofrontal angle, and nasal depth-nasal width index significantly increased. The nasal width, nasal tip width, and nasal index significantly decreased.
We performed tip plasty with the M-shaped auricular cartilage as modified septal extension graft, achieving a soft and mobile tip with satisfying tip projection in most patients.

鼻中隔延长移植物是亚洲鼻尖整形技术中最常用的移植物之一。然而，鼻中隔延长移植物通常会导致鼻尖坚硬且不活动。本研究旨在通过三维人体测量分析评估 M 形耳软骨改良鼻中隔延长移植物的美学效果。
共 36 例患者接受了 M 形耳软骨作为鼻中隔延长移植物联合硅胶植入物的隆鼻术。使用三维人体测量技术评估了 13 项测量项目，并比较了术前和术后的结果。
大多数患者（91.7%）对术后鼻形满意。未观察到感染、明显吸收、移植物暴露、植入物暴露或植入物迁移。与术前值相比，鼻长、鼻高、鼻深、鼻根高度、鼻中隔宽度、鼻唇角、鼻额角和鼻深-鼻宽指数显著增加。鼻宽、鼻尖宽度和鼻指数显著减小。
我们采用 M 形耳软骨作为改良鼻中隔延长移植物进行鼻尖整形，大多数患者的鼻尖表现为柔软、活动，鼻尖突出度满意。
