鼻唇沟区岛状皮瓣在鼻部皮肤缺损美学修复中的应用

Application of the Nasolabial Island Flaps in Repairing Nasal Skin Defect

目的:探讨应用鼻唇沟区岛状皮瓣在鼻部缺损修复中的效果。方法:回顾性分析32例因外伤或肿瘤切除后鼻部皮肤缺损患者应用鼻唇沟岛状皮瓣行鼻重建修复术后的功能恢复和美学效果。鼻重建方法采用同侧或对侧鼻唇沟区切取皮瓣,皮瓣长宽比例不超过4:1,蒂部去除皮下组织及表皮,保留真皮下血管网,穿过皮下隧道修复鼻部缺损,供瓣区两侧皮下游离后直接缝合。结果:本组共32例患者,随访6~12个月,其转移皮瓣均成活良好,无坏死,鼻部外观良好。供瓣区直接缝合后无继发畸形,切口瘢痕不明显,双侧面部对称,外观满意。结论:应用鼻唇沟区岛状皮瓣修复鼻部缺损虽是一种简单易行的手术方法,但可达到良好的功能修复和美学效果。

Objective To investigate the outcomes of the nasal reconstruction with nasolabial island flaps.Methods Postoperative functional and aesthetic outcomes of 32 patients with nasal defects caused by trauma or excision of skin malignancies,who underwent a nasal reconstruction with nasolabial island flaps,were retrospectively analyzed and summarized.Nasolabial island flaps with subcutaneous pedicle with the length-width ratio less than 4:1 were removed from ipsilateral or contralateral nasolabial sulcus.Then the subcutaneous tissue and epidermis in the pedicle were removed,but the subdermal vascular network was preserved.After that,the processed nasolabial island flaps through subcutaneous tunnels was used to repair the defects of the nose.Results In the 32 patients included in this study,the skin flaps in all cases were survived well without necrosis.This method promised a satisfactory cosmetic appearance without secondary deformities and visible scars.Conclusion The application of nasolabial island flaps in the nasal reconstruction is a simple and visible methods,it could promise a good functional and aesthetic outcomes.
