Suture techniques are an indispensable means to biologically sculpt the cartilage of the nose. Here the authors review their use in tip-plasty and present a 4-suture algorithm that allows for simple, complete control in sculpting the shape of all nasal tips in primary rhinoplasty. After a standard cephalic trim of the lateral crus leaving it 6 mm wide, one or more of the four suture techniques are applied. One of the newest techniques that has yielded excellent results is the hemi-transdomal suture, a variation of the conventional transdomal suture. This technique narrows the dome but also everts the lateral crus slightly to avoid concavities of the nostril rim. The 4-suture algorithm is useful in both the open and closed approaches. A more general use of sutures is described and referred to as the "universal horizontal mattress suture," which can be applied to remove all unwanted convexities or concavities and can be used not only to straighten the cartilage but also strengthen it. This suture has applications for the crooked septum, the collapsed lateral crus (external valve), and the collapsed internal valve, as well as for converting ear cartilage grafts into straighter, stronger grafts than previously thought possible.
缝合技术是对鼻软骨进行生物塑形的不可或缺的手段。作者在此回顾了其在鼻尖整形术中的应用,并提出了一种 4 缝线算法,可在初次鼻整形术中简单、完全地控制所有鼻尖的形状。在对外侧脚进行标准的头侧修剪后,使其保持 6 毫米宽,然后应用以下 4 种缝线技术中的一种或多种。其中一种效果极佳的新技术是半跨穹窿缝线,这是传统跨穹窿缝线的一种变体。该技术可缩小穹窿,但也会使外侧脚稍微翻转,以避免鼻孔边缘出现凹陷。该 4 缝线算法在开放式和封闭式入路中都很有用。缝线的更广泛应用被描述为“通用水平褥式缝线”,可用于去除所有不需要的凸凹,并不仅可用于使软骨变直,还可增强其强度。这种缝线可用于矫正鼻中隔偏曲、外侧脚塌陷(外部瓣)和内部瓣塌陷,以及将耳软骨移植物转变成比以前认为的更直、更强的移植物。
