The repair of nasal defects is a frequent challenge to facial plastic surgeons, mainly due to the high frequency of basal cell carcinomas. In general, small defects of up to 1 cm in diameter may be closed directly, whereas larger defects of up to 2.5 cm require the use of local flaps. For more extended defects, regional flaps such as the paramedian forehead flap are the method of choice. These rules have to be modified for the nasal tip, the alar region, the columella and the vestibulum where free skin grafts and auricular composite grafts have to be considered. In order to achieve pleasing aesthetic results, the aesthetic subunits of the nose have to be respected in each situation.
修复鼻缺损对面部整形外科医生来说是一项常见的挑战，主要是因为基底细胞癌的发病率很高。一般来说，直径达1厘米的小缺损可直接缝合，而直径达2.5厘米的较大缺损则需要使用局部皮瓣。对于更广泛的缺损，如正中旁前额皮瓣等区域皮瓣是首选方法。对于鼻尖、鼻翼区域、鼻小柱和鼻前庭，这些规则必须修改，在这些部位必须考虑使用游离皮片和耳廓复合移植物。为了获得令人满意的美学效果，在每种情况下都必须尊重鼻子的美学亚单位。
