A new principle for unilateral complete cleft lip repair, the lateral columellar flap method.

Abstract

This article presents a different method for unilateral complete cleft lip repair. The tissue deficiency of the medial lip segment is filled with a flap from the lateral surface of the columella, which is in continuity with the lip segment. The lateral columellar flap and the medial lip segment are lowered in one piece vertically downward to such a position that the height of the arch of the Cupid's bow is equal on both sides. No lateral advancement is done. The suture line of the medial and lateral lip segments is an uninterrupted straight line, which imitates the natural line of the philtral column. The repaired lip has more fullness than the lips repaired with the conventional methods. The procedure is described in detail.
