Due to the small and weak septal cartilage of Asians, it is a challenge to obtain ideal tip projection and nose lengthening in this population by performing septal extension grafts with only septal cartilage.
The aim of this study was to introduce a septal extension graft complex incorporating nasal septal cartilage, the perpendicular plate of the ethmoid bone, and bilateral auricular cartilage, and to examine its effectiveness in terms of morphological and mechanical support.
Septal cartilage was harvested under an endoscope according to standard techniques. Two pieces of the perpendicular plate of the ethmoid bone, placed on either side of the "L" strut, served as 2 spreader grafts. A double layer of auricular cartilage was fixed as columellar strut grafts. Three-dimensional facial scanning was used to examine the change of 3 parameters. Nasal tip resistance was evaluated by a digital Newton meter.
In total, 25 patients were followed up postoperatively for a mean of 25.9 months. The analysis showed significant differences in both contour parameters and nasal resistance: nasal length (mean [standard deviation], 41.4 [4.0] vs 46.2 [3.4] mm, P < 0.05) and nasal tip projection (21.3 [3.2] vs 24.4 [2.7] mm, P < 0.05) appeared to increase postoperatively, whereas nasolabial angle (117.6° [5.9°] vs 109.5° [5.3°], P < 0.05) showed a significant decrease after surgery. The resistance of the nasal tip also increased significantly (P < 0.05) at displacements of 1, 2, and 3 mm. All patients were satisfied with the aesthetic results, and no serious complications occurred.
This kind of modified septal extension graft technique can effectively adjust nasal morphology for short-nose East Asians.
由于亚洲人的鼻中隔软骨小而薄弱，因此仅使用鼻中隔软骨进行鼻中隔延伸移植对于获得理想的鼻尖突出度和鼻延长效果是一项挑战。
本研究旨在介绍一种包含鼻中隔软骨、筛骨垂直板和双侧耳软骨的鼻中隔延伸移植复合体，并评估其在形态和机械支撑方面的有效性。
根据标准技术在内窥镜下采集鼻中隔软骨。将两块筛骨垂直板放置在“L”支柱的两侧，作为 2 个撑开移植物。将双层耳软骨固定为鼻中隔支柱移植物。使用三维面部扫描检查 3 个参数的变化。使用数字牛顿米评估鼻尖阻力。
共有 25 例患者接受了平均 25.9 个月的术后随访。分析显示，在轮廓参数和鼻阻力方面均有显著差异：鼻长度（平均值[标准差]，41.4[4.0] 对 46.2[3.4]mm，P<0.05）和鼻尖突出度（21.3[3.2] 对 24.4[2.7]mm，P<0.05）术后似乎增加，而鼻唇角（117.6°[5.9°]对 109.5°[5.3°]，P<0.05）术后显著减小。鼻尖阻力在 1、2 和 3mm 位移时也显著增加（P<0.05）。所有患者对美学效果均满意，且无严重并发症发生。
这种改良的鼻中隔延伸移植技术可有效调整短鼻东亚人的鼻形态。
