摘要:
目的：探讨青少年骨性Ⅱ类高角患者和Ⅰ类均角颞下颌关节窝位置及形态的区别。方法：选取12～18岁青少年骨性Ⅱ类高角患者为试验组，骨性Ⅰ类均角患者为对照组，每组30例。利用Invivo5三维重建软件对颞下颌关节窝及其相关解剖结构进行三维指标的测量分析。结果：两组颞下颌关节窝最后点ar至前鼻嵴点Ans及蝶鞍点S的距离，颞下颌关节窝最低点ae至其在SN平面投影点的距离差异有统计学意义（均P＜0.05）。颞下颌关节窝最高点cf至后鼻嵴点Pns及蝶鞍点S的距离，颞下颌关节窝最高点cf在SN平面的投影点至蝶鞍点S的水平距离，颞下颌关节窝最高点cf至其在SN平面投影点的距离，颞下颌关节窝最后点ar至其在SN平面投影点的距离，颞下颌关节窝最高点cf与蝶鞍点S连线和SN平面所成角度具有显著差异（均P＜0.01）。结论：骨性Ⅱ类高角患者颞下颌关节窝的位置及形态与矢状面型有关联；骨性Ⅱ类高角患者的颞下颌关节窝更靠近颅底。
Abstract:
Objective: To explore the difference of position and shape of TMJ fossa between type Ⅱ high angle patients and type Ⅰ high angle malocclusion patients. Methods:12-18-year-old patients with high angle of bone type Ⅱ were selected as the experimental group and patients with average angle of bone type I as the control group, 30 cases in each group. Three dimensional indexes of TMJ fossa and its related anatomical structures were measured and analyzed by Invivo5. Results: The distance from the last point of TMJ fossa to the anterior nasal ridge and S point, and the distance from the lowest point of TMJ fossa to its projection point on SN plane were statistically significant (P<0.05). The distance from the highest point of TMJ fossa to the posterior nasal ridge and S point, the horizontal distance from the projection point of TMJ fossa in SN plane to the S point, the distance from the highest point of TMJ fossa to its projection point in SN plane, the distance from the last point of TMJ fossa to its projection point in SN plane, the angle between the highest point of TMJ fossa and the line of S point and SN plane had significant differences(P< 0.01). Conclusion: The position and shape of TMJ fossa in patients with high angle of bone type Ⅱ are related to sagittal type; TMJ fossa in patients with high angle of bone type Ⅱ is closer to skull base.
