The Nasal Symmetry After Surgical Repairing Unilateral Complete Cleft Lip With Improved Millard’s Method

Objective: Objective To evaluate the symmetry rate of nasal floor width for the unilateral complete cleft lip(UCCL)after repairs with improved Millard’s method.Methods: 30 cases of patients with unilateral complete cleft lip treated in oral and maxillofacial surgery from Ningxia Medical University General Hospital between January 2013 to August 2014,these patients all treated with improved Millard’s method. They were photographed before repair, 1 week, 3 month and 6 month after surgery. The distance from columella point to facial midline, the nasal floor width and the fissure width were measured. The approach rate of the columella point, the symmetry rate and the change of the nasal floor width were calculated. The statistical analysis was completed by SPSS 19.0.Results: There was statistical difference of the approach rate for the columella point between 1 week,3 month and 6 month after the surgery(52.93%, 53.71%,62.49%;P<0.05), no statistical difference was found of the symmetry rate for the nasal floor between 1 week,3 month and 6 month after surgical surgery(77.29%, 76.84%,76.26%; P>0.05). There was statistical difference of the change for nasal floor width between the cleft side and the non-cleft side in a week(P=0.000), but no statistical difference was found between 6 month and 3 month after the surgery of the cleft side and the non-cleft side. The linear correlation was obtained between the distance from columella point to facial midline 1 week after surgery and the distance from columella point to facial midline((r=-0.408, P=0.025)before surgery. No linear correlation was obtained between other index 3 month and 6month after the surgery and before surgery(P>0.05).Conclusion: 1、The symmetry rate of nasal floor width is stable after surgery with improved Millard’s method, and the growth changes have not significant impact on the effect of the surgery in six month.2、Postoperative nasal columella points to the recovery of facial midline distance is related with the size of the crack width of preoperative patients.
