“…Such new soft tissue relationships contribute to significant changes in the facial aesthetics and in the airway dimensions. (18)(19)(20)(21)(22)(23)(24) Accordingly, this retrospective study was designed to evaluate the volumetric, cross sectional surface area, and linear changes of the airway by using 3D cone beam computer tomography (CBCT) imaging after two different orthognathic surgeries in the Egyptian population.…”

“…(23)(24)(25) Abramson et al (23) found significant increases in lateral and anteroposterior airway diameters, volume, surface area, and cross-sectional areas at multiple sites following maxillary mandibular advancement with genial tubercle advancement. Parsi et al (24) and Hernández-Alfaro et al (25) found significantly increase in Oropharyngeal volume with an average percentage change (66.39%), (69.8%) respectively after bimaxillary advancement surgery. Chang et al (17) also found increase in Oropharyngeal airway volume after single mandibular advancement by (23.5%) after 6 months post operatively.…”

Objectives:The purpose of this study was to assess and compare the volumetric, cross sectional surface area, and linear changes of the oropharyngeal airway in patients following bimaxillary orthognathic surgery using 3-D cone beam computer tomography (CBCT) imaging. Material and Methods:A total thirty patients have been included in the study. Fifteen patients underwent maxillary and mandibular advancements (Group A), while the other fifteen patients underwent maxillary advancement and mandibular setback (Group B). Volume changes in airways, surface area, and linear values from specified hard and soft tissue parameters have been reported.Results: Statistical analysis comparing the results of the two groups showed that Group A was statistically significantly higher mean % increase than Group B in volumetric, surface area and linear measurements. Both groups failed to show a statistically significant change in surface area post-operatively. Group B showed no statistically significant change in linear measurements at any levels. Conclusion:Significant changes in the measured parameters was observed in patients performing maxillary and mandibular advancement thus increasing the airway volume; which can provide surgeons with a greater confidence that this combination movement is not altering the airway in a negative way.

“…3,9,12,13 Although there is clear evidence that bimaxillary advancement surgery can effectively increase the upper airway, 14,15 most studies have a limited number of patients. [16][17][18][19][20] Besides, they have not individually quantified the amount and percentages of upper air volume and minimum axial area increase. Therefore, the purpose of this study is to evaluate, in 3D images, the changes in the pharyngeal airway space (PAS) in skeletal Class I or Class II malocclusion patients, submitted to bimaxillary advancement surgery using bilateral sagittal split osteotomy for mandibular advancement, associated with maxillary advancement with Le Fort I maxillary osteotomy.…”

Introduction: The probability of improvement in the upper airway space (UAS) with orthognathic surgery should be considered during the surgical-orthodontic treatment decision, providing not only an esthetic, but also a functional benefit for the patient. Objective: The purpose of this study was to evaluate the 3D changes in the upper airway space after maxillomandibular advancement surgery (MMA). Methods: A retrospective analysis of 56 patients, 21 male and 35 female, with a mean age of 35.8 ± 10.7 years, who underwent MMA was performed. Pre- and postoperative cone-beam computed tomography scans (CBCT) were obtained for each patient, and the changes in the UAS were compared using Dolphin Imaging 11.7 software. Two parameters of the pharyngeal airway space (PAS) were measured: airway volume (AV) and minimum axial area (MAA). Paired t-test was used to compare the data between T0 and T1, at 5% significance level. Results: There was a statistically significant increase in the UAS. Bimaxillary advancement surgery increased the AV and the MAA, on average, by 73.6 ± 74.75% and 113.5 ± 123.87%, respectively. Conclusion: MMA surgery tends to cause significant increase in the UAS; however, this increase is largely variable.
