Popis: | The skeletal stability of Le Fort I osteotomy was evaluated retrospectively in 14 patients with isolated cleft palate (CP, mean age 27.2 years) and 11 patients with bilateral cleft lip and palate (BCLP, mean age 23.7 years). The osteotomy was fixed with titanium plates and the osteotomy gap was grafted with autologous bone. Neither intermaxillary fixation nor occlusal splints were used postoperatively. Skeletal stability was analysed both horizontally and vertically by cephalograms taken shortly before operation, immediately afterwards, and at six months and at one year postoperatively. In the CP group the mean maxillary horizontal advancement (point A) was 4.7 mm (range 0.3-7.8) and the mean vertical lengthening 3.6 mm (range 0.7-6.1). One year postoperatively the mean relapse was 8.5% (0.4 mm) horizontally and 16.7% (0.6 mm) vertically. In the BCLP group the mean horizontal advancement was 5.3 mm (range 0.2-10.7) and the mean vertical lengthening 7.3 mm (range 0.6-11.8). The mean postoperative relapse was 9.4% (0.5 mm) horizontally and 17.8% (1.3 mm) vertically. The skeletal stability and relapse were similar in both cleft types although BCLP patients had more residual cleft problems and their mean surgical advancement was greater. There was great individual variation. |
