| Abstract: | Surgeons face difficulties achieving simultaneous lip height and width symmetry while repairing unilateral complete cleft lip, so one is often sacrificed at the expense of the other. The aim of this study was to evaluate the effect of growth on lip height and width symmetry, to guide the surgeon to the best decision. The study patients (N = 105) were divided into two groups based on the treatment method: 42 were treated with the modified rotational advancement technique (MRA group) and 63 with the Millard rotation-advancement technique (RA group). Furthermore, based on lip height and width symmetry at 6 months postoperative, the patients were divided into three groups: 38 with symmetrical lip height and width (SL), 41 with horizontal lip width more symmetrical than lip height (RAW), and 26 with vertical lip height more symmetrical than lip width (RAH). Measurements were taken preoperatively (T0), 6 months (T1) and 5 years (T2) postoperatively. The MRA group had significantly more symmetrical lip height than the RA group at T1 (P = 0.003) and T2 (P = 0.002); however no statistically significant difference in lip width symmetry was observed between the two groups. In relation to the effects of growth, only lip width symmetry in the RAH group improved significantly between T1 and T2 (P = 0.023). In conclusion the improvement in lip width symmetry following 5 years of postoperative growth did not achieve the same symmetry as when lip width symmetry was achieved intraoperatively. Thus, the MRA technique could be used to obtain intraoperative symmetry of lip height and width. |
