背景：为了减少鼻尖球茎而切除旧的头侧小腿可能会加重和/或导致鼻翼后缩。对于那些表现出边缘性鼻翼后缩的患者来说，这是一个更严重的问题。方法：本研究由 14 名具有边缘性鼻翼/鼻小柱关系的鼻翼后缩的初次鼻整形术患者组成。他们不需要对鼻翼后缩进行坦率的治疗，但确实表现出鼻尖球状。头部外侧脚的“岛”是通过颈间切口形成的，另一个头部距外侧脚尾部边缘 6 毫米。在侧鸸鹋的主体上放置一根或多根褥式缝合线，使其阴沉并拉直。然后将头小腿的“岛”滑到侧小腿主体下方。结果：在 11 个月至 21/2 岁期间，14 名患者中的 13 名患者术前鼻翼/小柱关系没有表现出显着变化。所有患者的球茎均得到矫正。然而，一名患者需要使用鼻翼轮廓边缘移植物进行修正。术前鼻翼鼻孔轴的平均测量值为 1.48 毫米（范围为 1.3 至 1.9 毫米），而术后平均测量值为 1.71 毫米（范围为 1.5 至 2.2 毫米）。单尾配对 I 检验表明术前和术后值之间没有统计学上的显着差异。结论：外侧小腿的头侧部分可以作为外侧脚支柱将翼保持在更靠近尾部的位置。该技术对于边缘鼻翼后缩以及延长短鼻（需要保留侧壁长度）非常有用。 （马斯特重建外科 126：581，2010。）
Background: Resecting the cephalic component oldie lateral crus in an attempt to reduce tip bulbosity has the potential to aggravate and/or cause alar retraction. It is a more serious problem for those patients who exhibit borderline alar retraction.Method: Fourteen primary rhinoplasty patients with borderline alar/columellar relationships for alar retraction formed the study. They did not warrant frank treatment of alar retraction but did exhibit tip bulbosity. An "island" of cephalic lateral crus was developed by an intercarulaginous incision and another 6 mm cephalic to the caudal border of the lateral crus. One or more mattress sutures were placed in the main body of the lateral emus to sullen and straighten it. The "island" of cephalic crus was then slipped under the main body of the lateral crus.Results: At 11 months to 21/2 years, 13 of the 14 'patients demonstrated no significant change in their preoperative alar/columellar relationships. Bulbosity was corrected in all patients. One patient, however, required a revision using an alar contour rim graft The mean preoperative alar-nostril axis measurement was 1.48 mm (range, 1.3 to 1.9 mm) in contrast to a mean postoperative measurement of 1.71 mm (range, 1.5 to 2.2 mm) A one-tailed paired I test indicated no statistically significant difference between preoperative and postoperative values.Conclusions: The cephalic part of the lateral crus can act as a lateral crural strut to maintain the ala in a more caudal position. The technique is useful for borderline alar retraction and when lengthening the short nose for which there is a need to preserve side wall length. (Mast. Reconstr. Surg. 126: 581, 2010.)
