目的：比较单侧髁突增生（UCH）患者与III类骨骼关系患者的髁突体积。材料与方法：对20例患者的锥束计算机体层图进行分析。图像分为两组：10张来自面部横向不对称患者，10张来自III类面部畸形患者。患者年龄从15岁到30岁不等。使用Dolphin 3D软件（Dolphin Imaging & Management Solutions, Chatsworth， CA）重建体积数据。该软件测量了乙状骨切迹最深点以上的髁突体积、下弓中线偏差和过流。结果：增生髁体积最大（1.97 +/- 0.52 cm(3)），与对侧髁比较差异有统计学意义(chi(2) = 14.30；P
Purpose: To compare the condylar volume of patients with unilateral condylar hyperplasia (UCH) with that of patients with a Class III skeletal relation.Materials and Methods: Twenty cone-beam computed tomograms of patients were analyzed. Images were divided into 2 groups: 10 from patients with transverse asymmetry of the face and 10 from patients with a Class III facial deformity. Patients' ages ranged from 15 to 30 years. Volumetric data were reconstructed using Dolphin 3D software (Dolphin Imaging & Management Solutions, Chatsworth, CA). This software measured the condylar volume above the deepest point of the sigmoid notch, the lower arch midline deviation, and the overjet.Results: The condyle with hyperplasia exhibited the largest volume (1.97 +/- 0.52 cm(3)) and a statistically significant difference compared with the contralateral condyle (chi(2) = 14.30; P
