The purpose of this study is to make a 3-dimensional (3-D) evaluation of the pharyngeal airway space (PAS) in patients with class I, II, and III malocclusion.
Sixty patients were evaluated. The patients were divided in 3 groups according to their occlusion classification. The volume and area of PAS were evaluated using the software Dolphin 3-D Imaging in the preoperative period for orthognathic surgery.
PAS volume and area were influenced by different patterns of malocclusion. The mean volume and area for class III patients were statistically bigger than for classes I and II patients (P < .001). There was also a significant difference for volume values between class I and II patients, being the bigger volume for the class I patients (P < .05).
It was possible to conclude that the class III patients presented a bigger PAS compared with classes I and II patients.
本研究的目的是对安氏I类、II类和III类错牙合患者的咽气道间隙（PAS）进行三维（3-D）评估。
对60例患者进行评估。根据咬合分类将患者分为3组。在正颌手术术前，使用Dolphin 3-D成像软件评估PAS的体积和面积。
PAS的体积和面积受不同错牙合模式的影响。III类患者的平均体积和面积在统计学上大于I类和II类患者（P <.001）。I类和II类患者之间的体积值也存在显著差异，I类患者的体积更大（P <.05）。
可以得出结论，与I类和II类患者相比，III类患者的PAS更大。
