The lack of nasal tip support resulting in poor protection and projection of the nose is a common cause of nasal obstruction and cosmetic impairment. Although septal cartilage is preferred for restoration of nasal tip support, there is often not enough septal cartilage available. We describe an intercrural columellar strut graft in a circumferential soft tissue pocket: the I-Beam technique.
In this cohort study over an 8-year period the clinical and biometrical long-term results after restoration of nasal tip support with an autologous auricular cartilage graft, the I-Beam technique, is evaluated.
Out of the 72 consecutive septorhinoplasties with the I-Beam technique, we studied 66 patients in the median long-term follow-up of 89 months. In all patients a significant improvement in nasal tip projection was found. A functional improvement in nasal breathing was achieved in 86%. The overall satisfaction with the I-Beam graft was of 83%. No deterioration in smell perception was found after surgery.
The I-Beam technique using back-to-back sutured autologous auricular cartilage is a safe and effective technique and gives long-term structural support and enhances tip projection.
导致鼻子保护和突出度差的鼻尖支撑缺乏是引起鼻阻塞和美容损害的常见原因。尽管鼻中隔软骨是重建鼻尖支撑的首选材料,但通常鼻中隔软骨的量不足。我们描述了一种在环形软组织袋中使用鼻中隔-鼻翼软骨支柱移植物的方法:I 型梁技术。
在这项 8 年的队列研究中,我们评估了使用自体耳软骨移植物(I 型梁技术)重建鼻尖支撑的临床和长期生物测量结果。
在 72 例连续的鼻中隔成形术中,我们在中位数为 89 个月的长期随访中研究了 66 例患者。在所有患者中,均发现鼻尖突出度显著改善。86%的患者实现了鼻腔通气功能的改善。对 I 型梁移植物的总体满意度为 83%。手术后嗅觉感知没有恶化。
使用背靠背缝合的自体耳软骨的 I 型梁技术是一种安全有效的技术,可提供长期的结构支撑,并增强鼻尖突出度。
