ABSTRACT
<p><b>OBJECTIVE</b>To explore a new surgical method and its effect in repairing secondary nasal deformity of unilateral cleft lip.</p><p><b>METHODS</b>Sixty-two patients with secondary unilateral lip and nasal deformity were treated with asymmetric butterfly incision combined with vestibular V-Y advance flap, and the subjective and objective indicators after operation were observed.</p><p><b>RESULTS</b>All incisions healed with primary healing and all cases were followed up for 3-12 months. Fifty-eight cases got symmetric nostril and alar, the sum of absolute value of the nostril differences between both sides < 3 mm. Two cases got symmetric nostril and alar, but the sum of absolute value of the nostril differences between both sides was 3.5 mm and 4.2 mm respectively. The alar relapsed again in 2 cases and the results were not satisfied, the sum of absolute value of the nostril differences between both sides > 5 mm.</p><p><b>CONCLUSIONS</b>The method of using the asymmetric butterfly incision combined with vestibular V-Y mucosa flap can reset the skin,cartilages and mucosa to the anatomic position effectively.</p>
