SUMMARY: Improving the philtrum morphology of patients with a secondary cleft lip deformity has been a challenge in cleft care. Combining fat grafting with percutaneous rigottomy has been advocated for treatment of volumetric deficiency associated with a scarred recipient site. This study assessed the outcome of synchronous fat grafting and rigottomy for improvement of cleft philtrum morphology. Consecutive young adult patients (n=13) with a repaired unilateral cleft lip who underwent fat grafting combined with rigottomy expansion technique for enhancement of philtrum morphology were included. Preoperative and postoperative three-dimensional facial models were used for 3D morphometric analyses including philtrum height, projection, and volume parameters. Lip scar was qualitatively judged by a panel composed by two blinded external plastic surgeons using a 10-point visual analogue scale. 3D morphometric analysis revealed a significant (all p<0.05) postoperative increase of the lip height-related measurements for cleft philtrum height, noncleft philtrum height, and central lip length parameters, with no difference (p>0.05) between cleft and noncleft sides. The postoperative 3D projection of the philtral ridges was significantly (p<0.001) larger in cleft (1.01±0.43 mm) than noncleft sides (0.51±0.42 mm). The average philtrum volume change was 1.01±0.68 cm3, with an average percentage fat graft retention of 43.36±11.35 percent. The panel assessment revealed significant (p<0.001) postoperative scar enhancement for qualitative rating scale, with mean preoperative and postoperative scores of 6.69±0.93 and 7.88±1.14, respectively. Synchronous fat grafting and rigottomy improved philtrum length, projection, and volume and lip scar in patients with repaired unilateral cleft lip. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.
