The aim of this study was to evaluate the sagittal and vertical relapses after Le Fort 1 osteotomy in bilateral cleft lip and palate (BCLP) patients. Lateral cephalograms before surgery, immediately after the procedure, at one year, and at least two years (when available) after surgery were superimposed. The positions of five landmarks were studied in a coordinate system. Uni- and multivariate analyses investigated the effect of various factors on the relapse. Of the 71 patients included for a BCLP, 54 presented complete data at one year, and 30 patients were included for the long follow-up study (mean of 55 months). The mean maxillary advancement was 6.2 mm on the sub-spinal point (A). Sagittal relapse occurred at one year (mean of 1.1 mm on point A, 0.7 mm on point prosthion (P); p < 0.0001) and progressed by 0.5 mm and 1.0 mm, respectively, on the same points at the last follow-up. The mean vertical relapse was 0.5 mm on point A (p = 0.044), 0.6 mm on point P (p = 0.16) and 0.5 mm on incisor (I) (p = 0.056). The vertical relapse was correlated to the degree of vertical movement. Three factors were associated to the recurrence including a prior pharyngeal flap, an associated mandibular osteotomy and smoking habits.
