目的探讨东方人鼻部美容分区与鼻翼缺损修复手术方法选择的关系。方法如鼻翼缺损局限于鼻翼内2/3区域内,首选耳廓复合组织游离移植修复,在鼻翼创缘向内翻转局部皮瓣作为部分衬里;如缺损向内超过鼻翼区达鼻端区,向外超过鼻翼中外1/3交界,则首选同侧鼻唇沟真皮下血管网皮瓣修复。结果本组17例,其中11例选用耳廓复合组织游离移植,6例选择鼻唇沟真皮下血管网薄皮瓣行鼻翼修复。移植组织全部成活,鼻翼外形和色泽满意。结论依据鼻部美容分区选择手术,可使术后外形更加逼真,瘢痕更隐蔽。翻转局部皮瓣作为部分衬里可扩大移植物与受区的接触面积,提高成活率,并克服了直线瘢痕收缩形成鼻翼缘小缺口的不足。鼻唇沟真皮下血管网皮瓣血液循环可靠,再造鼻翼的臃肿程度大大减轻。
Objective To explore the relationship between oriental nasal cosmetic division and the selection of surgical methods for the repair of nasal alar defect. Methods such as the limitations of nasal alar is limited to 2/3 of the area within the nose, the first choice of auricle compound tissue graft free flap in the nose turned inward partial flap flap as part of the lining; such as the defect inward beyond the nasal wing up to the nose area, to Outside the nose beyond 1/3 junction, the preferred ipsilateral nasolabial fold subdermal vascular net flap repair. Results The group of 17 cases, of which 11 cases of auricular compound tissue graft free choice, 6 cases of nasolabial fold subdermal vascular net flap flap nasal repair. Transplant tissue all survived, nose shape and color satisfaction. Conclusion Based on the selection of nasal cosmetic surgery, the postoperative shape can be more realistic, the scar more hidden. Flip the local flap as part of the liner can expand the contact area of the graft and the affected area to improve the survival rate and overcome the lack of linear scar contraction to form a small gap of the nose flange. Nasolabial fold subdermal vascular network flap blood circulation reliable, greatly reduce the extent of reconstruction of the nose wing.
