自体软骨与膨体聚四氟乙烯在鼻整形手术中的应用

目的：通过应用自体鼻中隔软骨和耳软骨及膨体聚四氟乙烯解决鼻部美容整形的问题,以形成较理想的鼻形。方法：以鼻小柱飞鸟形切口加鼻翼软骨缘切口,切开分离鼻背皮肤,显露两侧鼻翼软骨及侧鼻软骨,中线分离弓形取出深部鼻中隔软骨,鼻中隔软骨雕刻塑形后插入两鼻翼软骨之间,并贯穿缝合形成中隔软骨＋鼻翼软骨为新的鼻小柱。将取下的耳软骨雕刻成杏仁状固定缝合于鼻小柱前端,雕刻好的膨体聚四氟乙烯插入鼻背固定,缝合切口。结果：20例美容就医者鼻部整形术后效果良好,自然美观,手感良好,无不良并发症发生,术后恢复时间略长。结论：应用自体鼻中隔软骨和耳软骨及膨体聚四氟乙烯行鼻部美容整形,能从根本上改变外鼻形态,是较理想的手术方法。

Application of autogenous cartilage combined with ePTFE in rhinoplasty

Objective To introduce a new method in rhinoplasty in order to shape the ideal nose with the combined application of septal cartilage of nose, ear cartilage, and expanded polytetrafluoroethylene （ePTFE） graft. Methods With combined incisions of midcolumellar gullwing and those inside the nostrils, the columellar flap is elevated with blunt scissor dissection to the superior aspect of the medial crura. The nasal tip skin is then elevated off the alar cartilages with gentle retraction and scissor dissection. The nasal dorsum is further exposed to harvest the septal cartilage. Sculped septal cartilage is inserted between the nasal alar cartilages, which is the new nasal columella. The harvested ear cartilage is sculped as shieidlike, and sutured in front of the nasal columella. The shaped ePTFE is inserted into the nasal dorsum and fixed before the closure of the incision. Results Satisfactory results are obtained in all 20 cases with natural and beautiful looking. No complications happen only with a longer recovery time. Conclusins This method with combined application of septal cartilage of nose,ear cartilage,and expanded polytetrafluoroethylene （ePTFE） graft in rhinoplasty is one of the good options to get the ideal shape of nose.
