From October 1996 to January 2001, 20 patients (14 men and six women) ranging from 36 to 75 years old have been treated for their small skin defects of the nose by using the bilobed flap. These skin defects were located in 15 cases at the alar region and in five cases at the tip region. They were secondary to the resection of basal cell carcinoma in 17 cases and benign tumors in three cases. Their diameter ranged from 8 to 17 mm and in all these cases there was no involvement of the lining or cartilage. The design used for this bilobed flap was the Zitelli one, based on some mathematical principles; its base was medial or lateral depending on the site of the defect. With this method, the skin defects were reconstructed esthetically without any distortion of local anatomy of the nose with skin having the same color, texture and thickness. With an average of 28 month follow-up, all these reconstructions were stable with discreet scars and without the trapdoor phenomenon. No complications were reported. Esthetic reconstruction of such subunit nasal skin defects is easily done by this technique and is better than that obtained by the majority of others methods.
1996年10月至2001年1月，采用双叶皮瓣对20例年龄在36至75岁之间的患者（14名男性和6名女性）的鼻部小面积皮肤缺损进行了治疗。这些皮肤缺损位于鼻翼区域15例，鼻尖区域5例。其中17例继发于基底细胞癌切除术后，3例继发于良性肿瘤切除术后。缺损直径为8至17毫米，所有这些病例中，内衬或软骨均未受累。该双叶皮瓣采用基于一些数学原理的齐泰利设计；其基部根据缺损部位位于内侧或外侧。通过这种方法，皮肤缺损得到了美观的修复，鼻部局部解剖结构未出现任何扭曲，皮肤的颜色、质地和厚度均相同。平均随访28个月，所有这些修复均稳定，瘢痕不明显，且无活板门现象。未报告并发症。通过这种技术可以轻松地对鼻亚单位的此类皮肤缺损进行美观修复，且效果优于大多数其他方法。
