Abstract

Congenital anomalies of the nose are distinctly unusual and appear at an incidence of 1 in 20,000 to 40,000 live births. Embrio-logically, developmental defects in the lateral nasal processes result in anomalies of the alar region. The defects of the lower lateral cartilage on one side and the different sizes of lower lateral cartilages cause problems in nasal tip support, contour, and symmetry. We present a case of congenital defect of the lateral crus of the right lower lateral cartilage of a 43-year-old male. The defect of the right lateral crus was reconstructed with the cartilage graft and the upper portion and the lateral crus of the left lower lateral cartilage were partially resected for symmetry of the nasal tip.

Figures and Tables

Fig. 1

Frontal (A) and basal (B) views of the nose shows profound nasal tip and nostril asymmetry.

A schematic picture of congenital total defect of the lateral crus of the right lower lateral cartilage.

Fig. 3

At surgery, the total defect of the right lateral crus was found. The replacement graft (16×9×3.5 mm) on the defect area was done with septal cartilage. The upper portion and lateral crus of the left lower lateral cartilage were resected 3 mm, 4 mm, respectively.

Fig. 4

Ten months after the rhinoplasty frontal (A) and basal (B) views of the nose show the aesthetic good results, despite of the persistence of nostril asymmetry.
