Table 6 The average skeletal movements of subjects after bimaxillary surgery

From: The structural changes of pharyngeal airway contributing to snoring after orthognathic surgery in skeletal class III patients

Skeletal movement Snoring group Non-snoring group p value
U1 set back (mm) 3.9 ± 1.53 1.8 ± 1.87 0.0121**
U1 up (mm) 2.6 ± 1.93 2.2 ± 1.45 0.665
PDI (mm) 3.8 ± 1.57 3.2 ± 1.05 0.412
B set back (mm) 9.7 ± 3.59 10.3 ± 4.33 0.772
B up (mm) 6.2 ± 2.64 7.6 ± 3.54 0.296
  1. Landmark measurements for surgical skeletal movements. The distances of maxillary and mandibular movements between prior to and after bimaxillary surgery were measured at PNS, U1, and B point.
  2. U1 maxillary first incisor insical edge, B points innermost curvature from chin to alveolar bone junction, PNS posterior nasal spine, PDI posterior differential impaction
