The modified Z-plasty for unilateral cleft lip repair

In 1965 Davies described a Z-plasty technique for the repair of a unilateral cleft lip. The technique has been modified so that the scars are more aesthetically placed and the orbicularis muscle correctly aligned. A prospective study was performed comparing the results of this modified Z-plasty with the rotation advancement repair. Twelve patients had a modified Z-plasty and 10 a rotation advancement repair. The modified Z-plasty compares favourably with the rotation advancement technique for the repair of a unilateral cleft lip. In particular, the incidence of asymmetry of lip height was greater in the rotation advancement group.
