Fig. 4From: Postoperative long-term results for the comparison of the symmetry of the upper lip during lip closure according to Millard and PfeiferRelation of vermillion length. Symmetry quotient of the lip vermillion length over the entire follow-up period in the Millard group (n = 36) compared to the Pfeifer group (n = 44) (p = 0.003).
