BACKGROUND Reconstruction of defects of the lateral nasal ala might be challenging. Reconstruction with a bi- or trilobed flap is common. The laterally based bi- or trilobed flap for defects of the distal ala or lateral tip of the nose produces mostly tissue protrusion in the nasal groove which is aesthetically unpleasant. Why not use more the medially based bi- or trilobed flap? OBJECTIVE To describe the utility of bilobed and trilobed flaps for alar defects insisting on the design of medially based flaps. METHODS To show the technique and practical application for this kind of reconstruction. RESULTS The bi- and trilobed flaps are useful for defect repair between the lateral nasal tip and the distal ala. We observed that in most cases the flap based medially respects anatomical subunits better than the laterally based flap for medium-sized defects of the distal ala of the nose. CONCLUSION I suggest that the bi- and trilobed flaps for repair of the lateral tip/distal ala should more often be medially based. This flap has a specific indication and precise advantage compared to other reconstructions, especially to the laterally based multilobed flaps in this specific indication.
