A new systematization for onlay tip grafting is described, using a minigraft constructed from either irradiated, glutaraldehyde-processed bovine cartilage or soft-grade silicone blocks. The graft design consists of two pyramidal volumes amputated in the apex and carved with mild concave surfaces. The lateral profile of the graft is asymmetrical with an acute inclination in the front and a slight inclination in the back. The graft height ranges from 1.5 to 3.8 mm. With this type of implant, high tip projection with a natural appearance can be achieved easily. Since 1986, we have performed 39 tip implants (12 cartilage grafts and 27 silicone grafts). Silicone graft fate has been excellent with no complications, whereas cartilage grafts underwent a 25% resorption rate. Thus, the current technique is now solely undertaken with silicone minigrafts. Main indications are primary tip plasty in normal-size noses with poor tip projection, and secondary noses. This technique is not recommended for simultaneous use with primary rhinoplasty. For more than 4 years, this technique has provided consistent results, being highly effective in achieving the objective of increasing tip projection.
本文描述了一种新的鼻小柱端植入物系统化方法，使用由辐照、戊二醛处理的牛软骨或软质硅胶块构建的微型移植物。移植物设计由两个在顶端截断并雕刻有轻度凹面的锥体组成。移植物的侧面轮廓不对称，前部倾斜度大，后部倾斜度小。移植物高度在1.5至3.8毫米之间。使用这种类型的植入物，可以轻松实现高鼻尖突出度且外观自然。自1986年以来，我们共进行了39例鼻尖植入手术（12例软骨移植和27例硅胶移植）。硅胶移植物效果极佳，无并发症，而软骨移植物的吸收率为25%。因此，目前该技术仅使用硅胶微型移植物。主要适应症为鼻尖突出度差的正常大小鼻子的初次鼻尖整形以及二次鼻整形。不建议将该技术与初次鼻整形同时使用。四年多来，该技术效果一致，在实现增加鼻尖突出度的目标方面非常有效。
