Congenital isolated alar defect (CIAD) is an extremely rare anomaly causing a remarkable aesthetic deformity. Up to today, only 6 previous cases have been reported, and there has been no technique approved as a criterion standard for the reconstruction of this anomaly yet. Here, we present a patient with a wide unilateral CIAD reconstructed with a new procedure, namely Mutaf's triangular closure technique. A 16-year-old adolescent boy was admitted to our clinic with a CIAD of 1.4 cm x 1.8 cm located on the left side. The reconstruction of the defect was done in a 3-layered fashion. The skin defect was covered by using the Mutaf's triangular closure technique in which 2 cutaneous local flaps designed in an unequal Z-plasty manner were used. The mucosal closure was achieved with a single mucosal transposition flap elevated from the superolateral alar region. A septal cartilage graft was placed between the skin and mucosal closure to replace the missing part of the lower lateral cartilage. Flaps healed with no complication. At 1 year after surgery, there was a cosmetically and functionally excellent result with almost symmetrical nostrils and minimal scar formation. Providing an aesthetic and anatomic reconstruction with alike local tissues, Mutaf's triangular closure procedure seems to be a useful option for reconstruction of the CIADs.
