The position of the nasal tip holds important aesthetic significance. Cephalic rotation of the nasal tip is a frequent motivating factor for patients seeking rhinoplasty. The position of the nasal tip is a complex interplay of the size, morphology, and position of several anatomical components of the lower one-third of the nose. Cephalic rotation can be achieved by means of six different methods. The indirect methods promote passive cephalic rotation and include cephalic trim of the lower lateral cartilages, caudal trim of the upper lateral cartilages, and caudal septal trim. Direct methods involve precise repositioning of the domes and include shortening the lateral crura, lateral domal relocation, and the tip rotation suture. Used alone or in combination, these techniques and their subtle variations represent comprehensive and effective methods to achieve cephalic rotation of the nasal tip.
鼻尖的位置具有重要的美学意义。鼻尖的头侧旋转是患者寻求鼻整形术的常见动机因素。鼻尖的位置是下三分之一鼻的几个解剖结构的大小、形态和位置的复杂相互作用。鼻尖的头侧旋转可以通过六种不同的方法来实现。间接方法促进被动的头侧旋转,包括下外侧软骨的头侧修剪、上外侧软骨的尾侧修剪和鼻中隔尾侧修剪。直接方法涉及穹窿的精确重定位,包括缩短外侧脚、外侧穹窿移位和鼻尖旋转缝合。这些技术及其细微变化单独或组合使用,代表了实现鼻尖头侧旋转的全面有效的方法。
