Abstract

The widely prevailing Millard's rotation-advancement flap method is characterizes with the upper lip scar on a philtral column and that it is less conspicuous than LeMesurier's or Tennison's metheds. Nowadays, straight line closure methods are employed together with the Millard's. However there are still some problems which are a straight line closure that goes against the principle of plastic surgery, a noticeable scar, tenting of the peak of Cupid's bow, a short lip tendency, and depression of the lip when the muscle contracts. In this respect, we designed two or three small trapezoid skin flaps on the cleft side and the same number of releasing incision lines on the non-cleft side and then let them interdigitate one another. We called it dovetail cheiloplasty. The muscle work was done by suturing one third of the cleft side muscle to the dissected dermis of the non-cleft side skin flap just under the philtral dimple. Our patients had a primary incomplete, a microform type cleft lip or a secondary cleft lip deformity. The result of employing this method showed an inconspicuous scar, a shorter lip, and a natural formation of the philtrum. We believe this method induces the improvement of straight line closure with respect to the quality of scars and the morphology of an upper lip.
