The creation of both a functionally and aesthetically pleasing nasal tip contour is demanding and depends on a variety of parameters. Typically, procedures are performed with emphasis on narrowing the nasal tip structure. Excisional techniques alone inevitably lead to reduction in skeletal support and are often prone to unpredictable deformities. But long-term results of classical suture techniques have also shown unfavorable outcomes. Particularly pinching of the alae and displacement of the caudal margin of the lateral crus below the cephalic margin belong in this category. A characteristic loss of structural continuity between the domes and the alar lobule and an undesirable shadowing occur. These effects lead to an unnatural appearance of the nasal tip and frequently to impaired nasal breathing. Stability and configuration of the alar cartilages alone do not allow for an adequate evaluation of the nasal tip contour. Rather a three-dimensional approach is required in order to describe all nasal tip structures. Especially the rotational angle of the alar surface as well as the position of the lateral crus in relation to the cranial septum should be considered in the three-dimensional analysis. Taking the various parameters into account the authors present new aspects in nasal tip surgery which contribute to the creation of a functionally and aesthetically pleasing as well as durable nasal tip contour.
塑造一个功能和美学上都令人满意的鼻尖轮廓具有挑战性,并且取决于多种参数。通常,手术重点在于缩小鼻尖结构。仅靠切除技术不可避免地会导致骨骼支撑减少,并且常常容易出现不可预测的畸形。但是传统缝合技术的长期效果也显示出不理想的结果。特别是鼻翼的挤压以及外侧脚尾缘移位到鼻小柱缘下方就属于这一类情况。穹窿和鼻翼小叶之间会出现典型的结构连续性丧失以及不理想的阴影。这些影响导致鼻尖外观不自然,并常常导致鼻腔呼吸受损。仅鼻翼软骨的稳定性和形态并不能充分评估鼻尖轮廓。相反,需要一种三维方法来描述所有鼻尖结构。在三维分析中尤其应考虑鼻翼表面的旋转角度以及外侧脚相对于鼻中隔的位置。考虑到各种参数,作者提出了鼻尖手术的新观点,这些观点有助于塑造一个功能和美学上都令人满意且持久的鼻尖轮廓。
