Objective To explore the effect of functional reconstruction in the reconstruction of transverse facial cleft.Methods From 2003 to 2011,11 cases with transverse facial cleft were repaired by functional reconstruction.The skin of cheek was crossed by Z flap to prevent the scar from shrinking straightly and the thin tissues from depressed deformity.Functional muscle trimming was done to repair the ring structure of musculus orbicularis oris.Results All the patients were followed for 3 to 12 months and there were no angular chilitis and formation of ulceration.The natural appearance of the lips,coordinate movements and plump cheeks were achieved.Conclusion Functional reconstruction of transverse facial cleft could improve the coordinate lip movements greatly and achieve natural facial expression.
