A new twist to the nasolabial flap for reconstruction of lateral alar defects.
The nasolabial flap remains the favored technique for alar and lateral nasal reconstruction. Results with currently popular techniques tend to be inartistic and aesthetically disappointing. Improved results can be achieved, however, by a technique using a medially based nasolabial turnover flap for lining with a distal extension providing the cover. Reconstruction of the ala begins by designing a nasolabial flap with its base as close as possible to the site of the proposed ala. The flap is incised to the required margins, carrying 2 to 3 mm of underlying fat; then, hinged on its base, the flap is flipped over medially like the page of a book. As the proximal flap is sutured to the lining side of the defect, the distal flap gracefully twists 90 degrees and is then folded on itself to form the external surface of the ala. The donor site is closed primarily. With this procedure, a natural-appearing and appropriately positioned ala may be reconstructed in one step, although a second procedure may be helpful to sculpture the margin or precisely position the alar base.
