Modification Inferior Triangular Flap Method Following Geometric Principle in Unilateral Cleft Lip Operation

Objective To investigate the modification inferior triangular flap method following geometric principle in order to advance the effect of traditional operation in unilateral cleft lip repair.Methods The mark point systems of columella base and injured alar base were analysed with geometric principle,and compared the differences between normal people and unilateral cleft lip patients in the triangle consisting of midpoint of columella base and both peaks of Cupid's bow.Results 158 cases were repaired by this procedure,and 139 cases improved satisfactorily.The symmetry of bilateral lip in triangular upper lip recovered nice.Conclusion This technique is an available method to repair the cleft lip for its definite mark point and strict theory base.
