自体鼻中隔软骨移植在鼻尖成形术中的应用

Autologous septal cartilage grafting in nasal tip augmentation

目的探讨自体鼻中隔软骨移植在鼻尖成形术中的应用。方法在双侧眶下神经阻滞麻醉下，采用“飞鸟形”切口显露鼻尖部。充分游离鼻翼软骨，切取2cm×1cm的鼻中隔软骨备用。将鼻中隔软骨切取1条移植于鼻翼软骨内侧脚之间，相互缝合后延长鼻小柱并抬高鼻尖。将剩余的鼻中隔软骨修剪塑形后，移植于鼻尖和鼻翼软骨表面。结果15例患者中，13例经3个月至1年半的初步随访，鼻尖形态均有不同程度的改善，效果满意。结论自体鼻中隔软骨是鼻尖成形术中较好的充填材料，没有排斥反应，值得进一步推广。

Objective To evaluate the role of autologous septal cartilage in nasal tip augmentation. Methods Under local anesthesia, nasal tip was exposed using a ＂bird-wing＂ incision. The hypertrophic tissue at the nasal tip was removed. Nasal septal cartilage （2 cm × 1 cm） was harvested. The cartilage was used to augment the nasal tip and nasal alar cartilage. Meanwhile, the cartilage was inserted between the nasal alar cartilages to elevate the nasal tip. Results Among 15 cases, 13 were followed after operation. The shape of nasal tip improved at different level. The results were satisfying. Conclusion Compared with other materials, the autologous septal cartilage is an ideal material for nasal tip augmentation without rejection effect.
