  1. All data of parameters were shown in the form of “Mean ± Standard deviation”
  2. Paired samples t-test analysis or Mann–Whitney tests was used to analyse the cleft and/or non-cleft sides of maxilla before operation (T1) and/or after operation (T2); Two-factor, two-level analysis for repeated measurement (r-ANOVA) was used to analyse the interaction between the sides of maxilla and time points;
  3. *Significant at P-value < 0.05;
  4. Maxillary length (Lmax): Sagittal distance from Am to Mt;
  5. Maxillary anterior width (AntWmax): Transverse distance from Lap to the MS plane;
  6. Maxillary posterior width (PosWmax): Transverse distance from Lap to the MS plane;
  7. Maxillary anterior height (AntHmax): Vertical distance from Or to ANS;
  8. Maxillary posterior (PosHmax): Vertical distance from Or to J;
  9. Maxillary volume (Vmax): Volume of the segmented individual maxilla;
