Philtrum Reconstruction Using Autogenous Fat Injection Versus a Surgical Repair in Secondary Unilateral Cleft Lip Revision

Two groups of patients with repaired unilateral cleft lip deformity having mild to moderate grooving and/or scarring of the philtral column and requiring a secondary cleft lip repair. * The first group will receive upper lip fat injections into the philtral column (and other areas of volume insufficiency if needed) after manual fat liposuction from the abdomen. * The second group will receive surgical lip revision with reconstruction of the orbicularis oris muscle using inverted horizontal mattress sutures for enhancement of the philtral ridge.
