Reconstruction of cupid's bow: a quadrilateral flap technique.

The cupid's bow is an important feature of the normal upper lip, and every effort should be made to reconstruct it during initial cleft lip surgery or trauma repair. However, a secondary surgical procedure is often necessary to improve the appearance and symmetry in the cupid's bow area. For this purpose, the authors present a quadrilateral type of interposition flap that can be used in both unilateral and bilateral cupid's bow reconstruction. This procedure is applicable only when adequate vermilion is available.
