M形软骨支架用于鼻尖成形术的临床效果

Clinical efficacy of M-shaped cartilage used in nasal tip cosmetic plasty

目的探讨M形软骨在鼻尖成形术中的应用。方法自2010年6月至2016年3月，共行33例鼻尖成形术。男6例，女27例。年龄22～46岁。用耳软骨裁剪并缝合成M形支架后移植于原大翼软骨位置，用于鼻尖支架构建。并使其部分固定于原有鼻中隔软骨上或鼻中隔延长后的软骨，进行鼻尖延长的美容术。结果平均随访1．2年，满意29例（87．9％），一般2例（6．1％）。感染2例（6．1％）。结论M形耳软骨支架也可用于鼻中隔延长后的鼻尖支架，其延长效果保持时间更长，且鼻尖形态和质感较盖帽和盾牌移植物更接近自然状态。

Objective To explore a new method of nasal tip plasty and its clinical effect, which is much accorded with biomechanical properties of the human body. Methods From June 2010 to March 2016, a total of 33 cases of nasal tip surgery, 6 males and 27 females, were performed. Ages ranged from 22 to 46 years in this group. Ear cartilage was trimmed into two strips and sutured them together in a ＂M＂ shape. When located to the original position of the nasal alar cartilage, the ＂M＂ shaped cartilage could be used in nasal tip; when fixing part of it on the nasal septum or lengthened nasal septal cartilage, the ＂M＂ shaped cartilage could be used in cosmetic surgery of nasal tip lengthening. Results The follow-up period was from one month to 60 months, with average 14 months. 29 patients （87.9%） were satisfied with the efficacy and 2 patients were suffered from infection （6.1%）. Conclusions When the M-shaped cartilage is fixed with lengthened nasal septum, it can lengthen the nasal tip much more and the contouring and texture of nasal tip are better than that of using a shield or a cap cartilage graft.
