Diced-cartilage grafts have been used for dorsal nasal augmentation for several years with good results. However, compounds such as Surgicel and temporalis fascia used as a wrap have inherent problems associated with them, predominantly inflammation and graft resorption. An autologous carrier could provide stabilization of cartilage grafts while avoiding the complications seen with earlier techniques.
In our patients, a malleable construct was used for dorsal nasal augmentation in which autologous diced-cartilage grafts were stabilized with autologous tissue glue (ATG) created from platelet-rich plasma (platelet gel) and platelet-poor plasma (fibrin glue).
A prospective analysis of 68 patients, who underwent dorsal nasal augmentation utilizing ATG and diced-cartilage grafts between 2005 and 2008, were included in the study. Although there was notable maintenance of the dorsal height, no complications occurred that required explantation over a mean follow-up of 15 months.
The use of ATG to stabilize diced-cartilage grafts is a safe, reliable technique for dorsal nasal augmentation. The platelet gel provides growth factors while the fibrin glue creates a scaffold that allows stabilization and diffusion of nutrients to the cartilage graft.
切丁软骨移植已被用于鼻背增高多年，效果良好。然而，像 Surgicel 和颞筋膜这样作为包裹物的化合物会引起一些固有问题，主要是炎症和移植物吸收。自体载体可以为软骨移植物提供稳定性，同时避免早期技术中出现的并发症。
在我们的患者中，使用一种可塑的构建物进行鼻背增高，其中自体切丁软骨移植用富含血小板的血浆（血小板凝胶）和血小板贫血浆（纤维蛋白胶）制成的自体组织胶（ATG）稳定。
对 2005 年至 2008 年间接受 ATG 和切丁软骨移植进行鼻背增高的 68 例患者进行了前瞻性分析。虽然在平均 15 个月的随访中，显著维持了鼻背的高度，但没有发生需要取出的并发症。
使用 ATG 稳定切丁软骨移植是一种安全、可靠的鼻背增高技术。血小板凝胶提供生长因子，而纤维蛋白胶形成支架，允许软骨移植物的稳定和营养扩散。
