Increasing nasal tip projection, rotation, and definition have classically been attempted through a variety of lobular cartilage incising or excising techniques. Resultant long-term complications, including bossing, alar notching, pinched tips, and alar collapse, have occasionally resulted from the use of these techniques. The majority of these complications have arisen secondary to a loss of structural support following the interruption of the lower lateral cartilages. This article describes the "lateral crural steal," a method of increasing nasal tip projection and nasal tip rotation while preserving the integrity of the lobular cartilage complex. The procedure uses the external rhinoplasty approach for exposure. By elevating both the dorsal and the vestibular skin from the domes of the lobular cartilages, the lateral crura may be advanced onto the medial crura to further project the nasal tip and to reorient the tip upward. This technique along with its philosophy and long-term follow-up results are presented.
传统上，人们尝试通过各种小叶软骨切割或切除技术来增加鼻尖突出度、旋转度和清晰度。使用这些技术偶尔会导致长期并发症，包括鼻背隆起、鼻翼切迹、鼻尖狭窄和鼻翼塌陷。这些并发症大多是由于下外侧软骨中断后结构支撑丧失所致。本文介绍了“外侧脚移位术”，这是一种在保留小叶软骨复合体完整性的同时增加鼻尖突出度和鼻尖旋转度的方法。该手术采用鼻外入路进行暴露。通过从小叶软骨穹窿处掀起鼻背和前庭皮肤，可将外侧脚推进到内侧脚之上，以进一步突出鼻尖并使鼻尖向上重新定位。本文介绍了该技术及其理念和长期随访结果。
