  1. Mean results are shown in bold and the most representative results of the changes between T0 and T1 in some children were also highlighted
  2. T&A = adenotonsillectomy, T0 = surgical indication, T1 = 18 months later, Palatal angle (°), Mento-Condyle length (mm), Palatal point displacement (mm), Condylion point displacement (mm), ANS-PNS (anterior nasal spine-posterior nasal spine) (mm)
