摘要/Abstract

摘要： 目的基于磁共振测量,研究青少年单侧颞下颌关节盘不可复性前移位对髁突高度的影响。方法选择2010年1月—2013年6月就诊并行随访观察的单侧颞下颌关节盘不可复性前移位青少年患者124例,平均年龄16岁,平均随访时间13.6个月。在磁共振片上测量髁突高度、盘长度及盘移位距离,比较健、患侧以及随访前、后的差异。采用SAS 9.13软件包对所得数据进行统计学分析。结果患侧关节盘移位距离从5.44 mm增大至6.83 mm（P<0.05）;患侧关节盘长度从9.06 mm缩短为8.12 mm（P<0.05）;健侧髁突高度从26.07 mm增加至26.82 mm（P<0.05）;患侧髁突高度从24.22 mm降低为23.81 mm（P<0.05）;健、患侧髁突高度差异从1.85 mm扩大为3.00 mm（P<0.05）。结论在青少年单侧颞下颌关节盘不可复性前移位患者病程中,患侧器质性病变继续进展,可能是单侧关节盘移位患者发生下颌偏斜的主要原因。

Abstract: PURPOSE：To evaluate the influence of unilateral temporomandibular joint anterior disc displacement without reduction on condylar height in juvenile patients during its natural course with quantitative measurement based on MRI. METHODS: The study collected 124 juvenile patients diagnosed with unilateral disc displacement without reduction and followed-up with MRI from January 2010 to June 2013,including 101 females and 23 males, with the mean age of 16.4 years and mean follow-up interval of 13.6 months. The disc length, displacement distance and condylar height were measured quantitatively on MRI. The difference was statistically analyzed with SAS 9.13 software package. RESULTS: The results showed that the mean displacement distance increased from 5.44 mm to 6.83 mm (P<0.05); The mean disc length of the affected sides reduced from 9.06 mm to 8.12 mm (P<0.05); The mean condylar height of the healthy sides increased from 26.07 mm to 26.82 mm (P<0.05); The mean condylar height of the affected sides reduced from 24.22 mm to 23.81 mm (P<0.05); The difference of condylar height between healthy and affected sides increased from 1.85 mm to 3.00 mm (P<0.05). CONCLUSIONS: During the natural course of temporomandibular joint unilateral disc displacement without reduction in juvenile, the organic disease tended to progress, which might finally contribute to maxillofacial abnormalities.
