鼻中隔尾段前徙术在鼻尖成形中的应用

Application of caudal septal advancement technique in nasal tip plasty

目的通过舜巾隔尾段前徙术．建立稳定的鼻尖支撑结构．以获得持久的鼻尖形态。方法应用弊中隔尾段前徙术重构鼻中隔，使鼻小隔前角及尾侧缘达到鼻尖预计的高度和长度；再将下外侧软骨窍窿、鼻噗内侧脚与鼻中隔尾侧缝合，从而形成稳定的鼻尖支撑结构。结果26例受术抒随访3～16个月．其中2例出现鼻背骨与软骨衔接处阶梯状改变，但鼻尖形态良好；3例原有鼻尖鼻小柱偏斜的患者．存3个月后出现再次偏斜，但较原先有一定改善；其余21例均鼻尖形态良好。结论利用鼻中隔尾段前徙术可形成稳定的鼻尖形态，是一种有效的疗法。

Objective To build the steady framework of the nasal tip by using caudal septal ad- vancement lechnique to obtain the permanent nasorostral configuration. Methods From Oct 2009 to Apr 2011, the caudal septal advancement technique was used to reconstruct the septum to make the septal anterior angel and the caudal septal margin reach the anticipated height and length of the tip, then medial crus and the vauh of the lower lateral cartilage were sutured to the caudal septum to form the steady supporting structure of the nasal tip. Results 3-16 months follow-up in 26 cases showed that 2 cases appeared the staircase deformity in the junction of the bone and the cartilage in the dor- sum. but the nasorostral configuration was good. 3 cases whose tip and columella were deviated before the operation appeared the deviation again after 3 months but the nasorostral configuration was better than before. The other 21 cases were good. Conclusions h is a available method of using caudal sep tal advancement technique to form the steady nasorostral configuratinn.
