Fig. 3From: Postoperative long-term results for the comparison of the symmetry of the upper lip during lip closure according to Millard and PfeiferRelation of Philtrum length. Symmetry quotient for the Philtrum length over the entire follow-up period in the Millard group (n = 36) compared to the Pfeifer group (n = 44) (p < 0.001).
