OBJECTIVE
To explore the relationship between the size of temporomandibular joint (TMJ) condyle and the sagittal disc-condyle position and the relationship between the condylar size and craniofacial structure.
METHODS
Seventy-four subjects (23.82 ± 3.77 years) underwent cone beam computed tomography (CBCT) and lateral cephalograms for orthodontics and volunteered to undergo magnetic resonance imaging (MRI). Mimics was used to calculate the volume and surface area of the condyle. MRI was used to evaluate the sagittal disc-condyle position. The lateral cephalograms were analyzed by Jarabak analysis.
RESULTS
The condylar volume and surface area were negatively correlated with the sagittal disc-condyle position. The condylar volume and surface area were positively correlated with Ar-Go, S-Go, and S-Go/N-Me*100% ( < 0.05) and negatively correlated with ∠Ar-Go-Me and ∠N-Go-Me ( < 0.05).
CONCLUSION
Condylar size was negatively correlated with the sagittal disc-condyle position. The condylar size was correlated with the vertical skeletal pattern.
目的
探讨颞下颌关节（TMJ）髁突大小与矢状盘髁突位置的关系，以及髁突大小与颅面结构的关系。
方法
74 名受试者（23.82±3.77 岁）接受了锥形束 CT（CBCT）和正畸侧位头颅侧位片，并自愿接受磁共振成像（MRI）检查。Mimics 用于计算髁突的体积和表面积。MRI 用于评估矢状盘髁突位置。侧位头颅侧位片通过 Jarabak 分析进行分析。
结果
髁突体积和表面积与矢状盘髁突位置呈负相关。髁突体积和表面积与 Ar-Go、S-Go 和 S-Go/N-Me*100%（<0.05）呈正相关，与∠Ar-Go-Me 和∠N-Go-Me（<0.05）呈负相关。
结论
髁突大小与矢状盘髁突位置呈负相关。髁突大小与垂直骨骼形态有关。
