Abstract: Objective:To improve the effects of contour and the function of cleft lip using improve Millard method. Methods:The operation of the upper lip, prismatical line and vermilion lip were designed accordiing to the method of Millard, Onizuka and Noordhoff, and oris orbicularis of contralateral side and nasal spine and base of diseased side were sutured by multi-level and place overlap. The founction of cleft lip were recovered, philtrum ridge was emerged and the recurrence of nasal feet offshoring was prevented. C flap shrink back to the bottom of nose to expand the skin of nasal columellar and bottom. Results:The equal height of bilateral lip, smooth margin of vermilion lip, natural lips bow and philtrum ridge were found without dry, staggering and ectropion vermilion lip. The upper lip movement without normal sag and distortion,the symmetry base of nasal alar to form nostrils were confirmed. The effects were good. Conclusions:The imprved Millard method is a valuable way,which can recover the founction of unilateral cleft lip.
