“斗拱”技术：基于鼻韧带解剖的注射鼻整形新型生物力学方法

文献信息

中文摘要

背景： 传统注射鼻整形常优先考虑浅层容积填充，这可能导致鼻部轮廓不自然、美学效果短暂以及各种并发症。
目的： 本研究介绍“斗拱”技术，这是一种受中国古代建筑启发的新型注射鼻整形生物力学方法，并评估其通过鼻韧带支撑改善鼻部轮廓的临床疗效。
方法： 对2025年1月至12月期间接受“斗拱”注射操作的100例患者进行回顾性分析。该技术针对五个精确解剖区域：鼻尖、鼻尖上区、鼻背、鼻根和鼻小柱基底。使用27-G锐针将透明质酸注射至骨膜或软骨膜上方，以增强鼻韧带的结构支撑。临床结局采用鼻整形结局评估（ROE）问卷以及疼痛、肿胀和总体满意度的视觉模拟量表（VAS）进行评估。客观结局通过4项鼻部标志点参数的照片测量分析呈现。
结果： 全部100例患者的鼻部美学均有所改善。VAS评分显示患者满意度高，同时操作相关疼痛和术后肿胀轻微。随访期间未观察到血管闭塞或材料移位等严重并发症。
结论： “斗拱”技术通过将临床重点从单纯的容积堆积转向生物力学韧带增强，为非手术鼻整形提供了一种初步可行的替代方案。未来需要前瞻性、随机对照研究来评估疗效，并与传统注射方式进行基准比较。

英文摘要

BACKGROUND: Traditional injection rhinoplasty often prioritizes superficial volume augmentation, which can lead to unnatural nasal contours, transient aesthetic effects, and various complications.
OBJECTIVE: This study introduces the "Dou-gong" technique, a novel biomechanical approach to injection rhinoplasty inspired by ancient Chinese architecture, and evaluates its clinical efficacy in enhancing nasal contour through nasal ligament support.
METHODS: A retrospective analysis was performed on 100 patients who underwent the "Dou-gong" injection procedure between January and December 2025. The technique targets five precise anatomical zones: the tip, supratip, dorsum, radix, and columella base. Hyaluronic acid was delivered above the periosteum or perichondrium using a 27-G sharp needle to reinforce the structural support of the nasal ligaments. Clinical outcomes were assessed using the Rhinoplasty Outcome Evaluation (ROE) questionnaire and visual analogue scale (VAS) for pain, swelling, and overall satisfaction. Objective outcomes were presented by photogrammetric analysis through 4 nasal landmark parameters.
RESULTS: All 100 patients demonstrated improvements in nasal aesthetics. VAS scores indicated high levels of patient satisfaction, accompanied by minimal procedural pain and postoperative swelling. No severe complications, such as vascular occlusion or material displacement, were observed during the follow-up period.
CONCLUSION: The "Dou-gong" technique provides a preliminary, feasible alternative in non-surgical rhinoplasty by shifting the clinical focus from mere volume accumulation to biomechanical ligament reinforcement. Future prospective, randomized controlled investigations are required to evaluate efficacy and benchmark performance against conventional injection modalities.
