Non-melanoma skin cancers are the most frequent skin tumours; in 25.5% of cases, they are reported to affect the nasal area. For an excellent surgical outcome, first of all the radical excision of the lesion is important, with appropriate margins of healthy skin in order to avoid recurrences. Moreover is important to achieve a good aesthetical result, avoiding distortion of the aesthetic units and preserving their functions.
We have applied the modified crescentic flap, described by Smadja in 2007, to 24 nasal skin defects left by oncologic surgery. It consists of the crescent-shaped resection of Burow's triangle all around the alar groove that allows the advancement of the flap to the tip of the nose, hiding the scar in the alar groove.
The outcome and the long-term follow-up were completely satisfactory both for patients and for surgeons.
For skin defects localized in the midline or paramedian line of the dorsum of the nose, the crescentic flap seems to be a good solution to obtain the better aesthetic result with respect to both anatomy and function of the nasal area, sparing the patient a second intervention or an overly invasive procedure.
非黑色素瘤皮肤癌是最常见的皮肤肿瘤；据报道，25.5%的病例会累及鼻区。为了获得出色的手术效果，首先，病变的根治性切除很重要，要有适当的健康皮肤切缘以避免复发。此外，实现良好的美学效果也很重要，要避免美学单元的变形并保留其功能。
我们将Smadja于2007年描述的改良新月形皮瓣应用于24例肿瘤手术后遗留的鼻皮肤缺损。它包括在鼻翼沟周围对布罗三角进行新月形切除，使皮瓣向鼻尖推进，将瘢痕隐藏在鼻翼沟内。
患者和外科医生对结果及长期随访都完全满意。
对于位于鼻背中线或旁中线的皮肤缺损，新月形皮瓣似乎是一个很好的解决方案，就鼻区的解剖结构和功能而言，能获得更好的美学效果，使患者避免二次干预或过度侵入性手术。
