Application of modified vermillion flap and orbicularoris oris bundle anastomosis in repair of transverse facial cleft

To improve the method of vermillion flap and orbicularis oris bundle anastomosis in repair of transverse facial cleft. Based on the precise fixed point, the modified vermillion flap was designed slender at the new corner of the upper lip, and was inserted into the lower lip after removing part tissue. The orbicularis oris was divided into two bands and cross-stitched. Fifteen patients with unilateral transverse facial cleft form the Children's Hospital of Zhejiang University during September 2016 and December 2018 were operated, and the position and shape of the commissure were almost normal. The cosmetic effect and oral function are satisfactory when the modified vermillion flap and bundle anastomosis of orbicularis oris is used to repair transverse facial cleft.
