摘要： 目的　探讨采用锥形束CT（CBCT）髁状突体积分析进行髁状突骨折后患者颞下颌关节（TMJ）骨性形态测量的价值。方法　选择2017年1月至2019年5月髁状突骨折患者28例，获取CBCT图像，比较健、患侧手术前后TMJ骨性形态指标（两侧的髁状突体积）。结果　术后患侧髁状突体积大于健侧（P＜0.05），并明显小于术前（P＜0.05）。结论　单侧髁状突骨折前后的体积变化与健侧有显著差异，这可能是术后TMJ功能评定的新标准。

Abstract: Objective　To explore the value of condylar volume analysis based on cone beam CT(CBCT) in the measurement of the temporomandibular joint (TMJ) morphology of patients with condylar fractures. Methods　From January 2017 to May 2019, 28 patients with condylar fracture were enrolled. CBCT images were analyzed. Preoperative and postoperative TMJ bone morphology indexes (left condyle volume and right condyle volume) were compared between the fractured side and the non-fractured side. Results　The condylar volume on affected side after fracture operation was larger than that on non-affected side (P<0.05), and the condylar volume was reduced after surgery (P<0.05). Conclusion　The changes of condylar volume of patients with condylar fractures before and after surgery have significant difference between the fractured side and the non-fractured side. This may be a new standard for postoperative TMJ functional evaluation.
