目的:探讨鼻唇沟带蒂皮瓣在修复鼻翼恶性肿瘤术后缺损的临床实用性和可行性。方法:对11例鼻翼恶性肿瘤患者行手术切除肿瘤,并根据鼻唇沟面部血供特点及缺损区大小设计出需要修复区域的长度、角度和体积,设计鼻唇沟面部带蒂皮瓣。经鼻侧移至缺损区修复鼻翼缺损区。结果:所有患者术后伤口均Ⅰ期愈合,皮瓣全部成活,血液循环良好,色泽良好,供区无明显瘢痕。术后随访1～5年,肿瘤无复发,外鼻美容修复效果满意。结论:鼻唇沟带蒂皮瓣血运丰富,易成活,可提供足够的组织量用以修复较大面积鼻翼缺损,且血管蒂长,转移灵活,操作简便,供区无明显瘢痕。鼻唇沟带蒂皮瓣是修复鼻翼恶性肿瘤切除术后较大面积缺损的最佳皮瓣。
Objective: To investigate the clinical feasibility and feasibility of nasolabial cleft pedicle flap in the repair of postoperative defect of nasal malignant tumor. Methods: 11 cases of nasal malignant tumors were surgically resected. The length, angle and volume of the repaired area were designed according to the characteristics of blood supply to the nasolabial fold and the size of the defect area. Transnasal to the defect area repair nasal defect area. Results: All the patients had primary wound healing, the flaps all survived, the blood circulation was good, the color was good and there was no obvious scar in the donor area. Follow-up 1 to 5 years after surgery, no recurrence of tumor, external nasal cosmetic repair satisfactory results. CONCLUSION: The nasolabial fissure pedicle flap is rich in blood flow and easy to survive. It can provide sufficient amount of tissue to repair large area of nasal defect, and has long vascular pedicle, flexible transfer, easy operation and no scar for donor area. Nasolabial fissure flap is the best flap to repair large area defects after resection of nasal malignant tumors.
