Reconstruction of a columellar defect with a nasolabial island flap.

Columellar skin defects may be caused by excision of cutaneous malignancy, trauma, or tissue necrosis associated with surgery. Although columellar skin necrosis rarely occurs following rhinoplasty, this condition might be more common when using an external approach than a closed approach. Columellar skin incision performed with exaggerated tip augmentation may cause columellar necrosis. The nasolabial island flap, used unilaterally to cover columellar skin defects, is used for a single-stage reconstruction procedure and is generally not associated with the need for secondary surgeries. This technique is well suited for repairing columellar skin defects. We experienced a patient with columellar skin necrosis occurring after rhinoplasty which was reconstructed using a unilateral single-stage nasolabial island flap.
