“…Maxillomandibular advancement surgery has been shown to be very efficacious in the elimination of OSA because it enlarges the pharyngeal airway space and tightens the upper airway muscles and tendons, mainly the velopharyngeal and suprahyoid muscles, by advancement their bony origin 7,23,24 .…”

“…In contrast, mandibular setback surgery is known to cause a narrowing of pharyngeal airway 2,[7][8][9][10][11][12]17,19 . Previous studies have shown changes in the positions of the tongue and the hyoid bone and consequent narrowing of the PAS after orthognathic surgical procedures in a pattern closely resembling that seen in sleep apnea subjects [9][10][11][12]17,19 .…”

“…Elastics were placed maintain the ideal occlusion after IMF The preoperative CT evaluation of individual patients was performed within a week before the surgery. The postoperative CT evaluation was performed at least 3 months after surgery for all patients as referred by many authors 2,[7][8][9]24 . Informed consents were obtained from all patients and the study was approved by Kanazawa University Hospital Committee on Human Research.…”

“…Recently, several studies attemped to investigate the effect of orthognathic surgery on the PAS in patients with Class III deformities 2,[6][7][8][9][10][11]17 . Most of these either investigated only the effects of mandibular setback surgery for the correction of the mandibular prognathism or the only resources used to investigate the structures of the pharyngeal airway was lateral cephalometric radiographs (LCR).…”

Purpose: The purpose of this study was to compare the morphologic changes of the upper airway space in Class III patients underwent mandibuler set back or bimaxillary surgery (maxillary advancement and mandibular setback) by computed tomography at 2 levels: soft palate and base of tongue Materials and Methods:The sample is consisted of 47 patients in 2 groups who had been diagnosed with Class III skeletal deformities and had been treated by mandibular setback or bimaxillary surgery (maxillary advancement and mandibular setback).Anteroposterior, lateral, cross sectional area dimensions of the airway at the level of soft palate and base of tongue was measured pre-and postoperatively on computed tomography images.Results: However, anteroposterior dimensions of the airway decreased in both groups (p<.0001), the reduction was significantly less in cases treated with bimaxillary surgery (p<.05). In mandibular setback surgery group, the cross sectional area of the airway decreased significantly (p<.001) Although, the cross sectional area of the airway decrease in bimaxillary surgery group, the reduction was not statistically significant (p>.05).Conclusions: This study suggested that bimaxillary surgery could prevent narrowing of the upper airway in the correction of Class III deformities rather than mandibular setback surgery .
