The marking of the medial lip segment of the Millard rotation advancement procedure for repair of the unilateral cleft lip has been altered in the uppermost portion by utilizing tissue from the columellar base. Once adequate length has been obtained, cutback is utilized at approximately 90 degrees. With adequate full-thickness release of this medial lip segment and subsequent rotation into the proper position, the C flap is advanced into the donor defect of the columellar base and is also used to lengthen the shortened columella on the cleft side. This results in placement of a scar that will closely simulate the "mirror image" of the noninvolved philtral column. Fifty-seven patients with unilateral cleft lip have been repaired utilizing this technique during the past 14 years. Several of these children have required secondary surgeries because of mucosal irregularities or residual nasal deformities, but none has required additional surgery because of inadequate rotation of the medial lip segment or for correction of any donor-site defect at the base of the columella.
