Repair of unilateral cleft lip: a comparison of five techniques.

ABSTRACT

Repair of unilateral cleft lip is a challenging procedure with no single technique satisfactory for all types of unilateral cleft deformity. This study compares retrospectively five techniques of unilateral cleft lip repair in 72 children (45 boys, 27 girls). Twenty-two children had a Millard rotation-advancement repair, 5 children had a Davies Z-plasty, 22 had a modified Z-plasty, 10 had a Tennison-Randall triangular flap repair, and 13 had a Nakajima-Yoshimura straight-line repair. Assessment was performed clinically by a plastic surgeon not involved in the original surgery. Repairs were assessed objectively by measurement of the vertical length of both the repaired and normal sides of the lip with calipers. Subjective criteria used to evaluate the repair were the symmetry of Cupid's bow, the quality of scar, the alignment of white roll, the evenness of the vermilion, and the lip pout. The mean follow-up period was 5.4 years (range, 9 months-29 years). Sixty-five of the 72 repairs measured (90%) were within two standard deviations (SDs) of normal and thus were considered to be of "acceptable" length. Seven repairs were unacceptably short (>2 SDs) on measurement, six of which included a rotation-advancement repair for a complete cleft lip. Subjective results paralleled the objective results. The outcome following repair of unilateral cleft lip was similar for all five surgical methods assessed except for complete cleft lips repaired by the rotation-advancement technique, which tended to result in an unacceptably short lip as measured on the repaired side.
