Int J Oral Max Surg:逆时针方向双颌前移和关节盘复位术后的髁突变化

2018-04-18 MedSci MedSci原创

本研究调查了逆时针双颌前移(CCW-MMA)和关节盘复位术后髁突重塑变化的预测危险因素。

本研究调查了逆时针双颌前移(CCW-MMA)和关节盘复位术后髁突重塑变化的预测危险因素。

四十一名女性患者(75例髁状突)采用CCW-MMA和椎体重新定位,术前,术后即刻和术后平均16个月进行锥形束计算机断层扫描(CBCT)扫描。术前术后三维模型叠加使用颅底基于体素的自动匹配,以评估术后髁突位移。在随访期间进行区域标记以评估髁突重塑。应用三维头颅测量,形状对应(SPHARM-PDM)和体积测量来量化变化。 Pearson乘积矩相关和多元回归分析被执行。

高度统计学显着相关性显示,老年患者更容易受CCW-MMA和关节盘复位后整体髁突体积减少的影响(P≤0.001)。随访期间髁突重塑变化与手术前面部特征,外科手术程度和髁突位移变化之间存在较弱但统计学显着的相关性。在CCW-MMA和关节盘重新定位后,髁突大部分向下和向内移动,并且向内侧和逆时针旋转;相反方向的位移与髁吸收的风险更高相关。此外,手术的位置变化与后续阶段的重塑只有微弱的关联,这表明其他风险因素可能在髁突吸收中起作用。
