Abstract
PURPOSE
This clinical study aimed to design and utilize a modified rotation-advancement technique (MRAT) with a resembling rectangular flap on the lateral lip for primary unilateral cheiloplasty and evaluated its postoperative outcomes.
MATERIALS AND METHODS
A retrospective study was conducted on patients with a unilateral cleft lip who had undergone initial cheiloplasty with MRAT. The postoperative outcomes were assessed for nasolabial symmetry by photogrammetry. Repeated measures of ANOVA and two independent samples t tests were applied for statistical analysis.
RESULTS
Twenty patients with unilateral cleft lip met the inclusion criteria. Postoperatively, the patients had well-shaped nasal sill and centered nasal columella. In addition to, the bilateral symmetrical ratios noticeably improved ( P <0.001). Simultaneously, the postoperative outcomes were independent of the cleft type and height differences of the two peaks ( P >0.05).
CONCLUSIONS
Unilateral cheiloplasty using the present MRAT can better preserve the nasolabial structure and symmetry. The postoperative scar is concealed and simulates a normal philtral ridge.
