Abstract
Objective: To evaluate the relationship between the changes in condylar volume and maxillofacial skeletal morphology according to sex as well as the relationship between condylar volume reduction and skeletal relapse in patients who underwent orthognathic surgery.
Methods: Ninety-five patients were categorized into skeletal Class III, Class II, and facial asymmetry groups. Computed tomography scans taken preoperatively and at 1 year postoperatively were used for quantitative measurement.
Results: Postoperative condylar volume was reduced in both the Class II group and the deviated side of the asymmetry group. Both female and Class II deformity were significant predictors of postoperative reduction in the condylar volume. There was a significant correlation between skeletal relapse and postoperative change in condylar volume in the Class II group.
Conclusion: Postoperative condylar resorption may be associated with preoperative maxillofacial skeletal morphology and sex and also with skeletal relapse in the Class II group.
目的评估接受正颌手术的患者髁突体积变化与颌面部骨骼形态之间的性别关系,以及髁突体积缩小与骨骼复发之间的关系:将 95 名患者分为骨骼 III 级、II 级和面部不对称组。采用术前和术后一年的计算机断层扫描进行定量测量:结果:Ⅱ类组和不对称组偏斜侧的术后髁突体积均有所减少。女性和 II 类畸形都是术后髁突体积缩小的重要预测因素。在II度畸形组中,骨骼复发与术后髁突体积变化之间存在明显的相关性:结论:术后髁突吸收可能与术前颌面部骨骼形态和性别有关,也与II类组的骨骼复发有关。
