| Research Abstract |
To investigate using computational fluid dynamic the relationship between morphology and pressure drop in PAS caused by mandibular setback surgery, each three-dimensional airway model was constructed from the preoperative and the postoperative CT data of 10 patients with mandibular protrusion who underwent mandibular setback surgery. The pressure drop was calculated in PAS. Flow simulation of airway was performed at the inspired air flow rate (200ml/s). In all cases, the pressure drop in PAS increased after mandibular setback surgery and has the high correlational relationship with the minimum cross sectional area at soft palatal level. When the cross sectional area was less than 1 cm2, the pressure drop in PAS tends to increase greatly.
