Reconstruction of longitudinal defects of the lateral nasal alar might be challenging. Reconstruction with a bilobed flap is common for round defects normally the bilobed flap is less suited for longitudinal defects.
We describe a birhombic flap for longitudinal defect.
Demonstration of the technique and practical application for this kind of reconstruction.
The bilobed flap is a very useful flap for lateral nasal tip or distal alar reconstruction. We show that a small modification of the flap allows to cover also longitudinal defects on the lateral tip of the nose. As the first lobe movement corresponds more to the rhomboid transposition flap, we prefer to call it birhombic flap.
The birhombic flap has its place in reconstructive surgery. This flap has a specific indication and precise advantages to other repairs in particular to the bilobed flap.
横向鼻翼侧方的纵向缺损的重建可能具有挑战性。通常使用双叶皮瓣进行圆形缺损的重建，但双叶皮瓣不太适合用于纵向缺损。
我们描述了一种用于纵向缺损的双菱形皮瓣。
演示这种重建技术的实际应用。
双叶皮瓣对于鼻翼外侧或鼻翼远端的重建是非常有用的皮瓣。我们展示了对皮瓣的一个小的修改，使其能够覆盖鼻子外侧尖端的纵向缺损。由于第一叶瓣的运动更类似于菱形皮瓣的转位，因此我们更倾向于将其称为双菱形皮瓣。
双菱形皮瓣在重建外科中有其特定的应用。与其他修复方法（特别是双叶皮瓣）相比，这种皮瓣具有特定的适应证和显著的优势。
