Abstract

Introduction

Dorsal augmentation enhances nasal dorsum height and contour. Existing techniques face challenges like resorption, infection, and migration. This study introduces Stratified Dorsal Augmentation, a multi-layered cartilage grafting approach to improve stability and aesthetics.

Methods

A total of 68 patients (19 males, 49 females) underwent open structural rhinoplasty (2020–2023). Autologous costal cartilage was harvested (7th rib in females, 8th in males) using U-shape technique. Grafting involved: (1) diced cartilage for surface smoothing, (2) a solid 2 mm obliquely split costal cartilage graft for structure, (3) an additional diced cartilage layer for contouring, and (4) a perichondrium overlay for stability. The average follow-up was 29 months.

Results

All patients achieved the desired dorsum height. No cases of graft rejection, migration, or warping occurred. Two vestibular infections resolved with antibiotics, and two minor bleeding cases were managed conservatively. Three patients required minor secondary revisions.

Conclusion

The Stratified Dorsal Augmentation technique minimizes warping, migration, and resorption, while ensuring both long-term stability and a natural appearance, making it a safe and effective alternative for dorsal augmentation.

分层背部增强术-一种新的背部重建技术

背侧隆胸增强鼻背高度和轮廓。现有技术面临着吸收、感染和迁移等挑战。本研究介绍了分层背侧增强术，一种多层软骨移植方法，以提高稳定性和美观性。方法2020-2023年，68例患者（男19例，女49例）行开放性结构鼻成形术。采用u形技术摘取自体肋软骨（女性第7肋，男性第8肋）。移植涉及：(1)切成小块的软骨用于表面平滑，(2)一个实心的2毫米斜裂肋软骨移植物用于结构，(3)一个额外的切成小块的软骨层用于轮廓，(4)一个软骨膜覆盖层用于稳定性。平均随访时间为29个月。结果所有患者均达到预期的背高。无移植物排斥、移位或翘曲发生。2例前庭感染用抗生素治疗，2例轻微出血保守处理。3例患者需要轻微的二次翻修。结论分层背隆术在保证长期稳定性和外观自然的同时，最大限度地减少了弯曲、迁移和吸收，是一种安全有效的背隆术替代方法。证据水平
