The alar cartilages provide the contour and structural support of the nasal tip. Current rhinoplasty concepts support preservation of alar structure with suture techniques or judicious cephalic trim indicated for tip deformities. In many primary cases and some revisions, adequate alar structure exists to achieve the desired aesthetic and functional results with conservative surgical methods. In some primary and most revision cases, however, the existing tip structure is inadequate to create a structurally sound and aesthetically pleasing nasal tip without adding structure. In these cases, alar cartilage grafting techniques are indicated to recapitulate nasal tip contour and structure.
鼻翼软骨为鼻尖提供轮廓和结构支撑。当前的鼻整形术概念支持通过缝合技术或明智的额侧修剪来保留鼻翼结构，以矫正鼻尖畸形。在许多初次手术和一些修复手术中，通过保守的手术方法，鼻翼结构的存在足以实现理想的美学和功能效果。然而，在一些初次手术和大多数修复手术中，现有的鼻尖结构不足以在不增加结构的情况下创建一个结构合理且美观的鼻尖。在这些情况下，需要使用鼻翼软骨移植技术来重现鼻尖轮廓和结构。
