Basal cell carcinomas commonly involve the medial canthal region and reconstruction of medial canthal defects is a challenging problem in reconstructive surgery. A new axial pattern flap raised from radix nasi region has been successfully used for the medial canthal defects in eight patients in figure-of-eight manner. One of the ellipses of the figure of eight is the defect, the other is the radix nasi flap. The radix nasi flap with a dimension up to 25 mm is transposed to the defect based either on ipsilateral anastomosis of the dorsal nasal artery with angular artery (AA) or with the connection of its source artery (i.e. ophthalmic artery) if the AA is damaged. All flaps survived and no tumour recurrence was observed. The donor sites were closed primarily and hidden at the radix nasi crease in all cases. The radix nasi flap in figure-of-eight fashion is good alternative for defects of the medial canthal area in terms of attaining a suitable colour and texture and minimal surgical scars.
基底细胞癌常累及内眦区域，而内眦缺损的重建是重建外科中的一个难题。一种从鼻根区域提起的新型轴形皮瓣已成功地以 8 字形方式用于 8 例内眦缺损患者。8 字形的一个椭圆是缺损，另一个是鼻根皮瓣。鼻根皮瓣的尺寸可达 25mm，可根据鼻背动脉与内眦动脉（AA）的同侧吻合（如果 AA 受损，则与供应动脉的连接）转移至缺损部位。所有皮瓣均存活，未观察到肿瘤复发。所有病例均将供区直接缝合，隐藏于鼻根皱褶处。从颜色和质地以及最小的手术疤痕方面来看，8 字形的鼻根皮瓣是内眦区域缺损的良好替代方法。
