OBJECTIVE
To investigate the electrosonography character of sounds emanating from anterior disc displacement with reduction of TMJ and the value of it in clinical diagnosis.
METHODS
The sounds from healthy TMJ, anterior disc displacement with or without reduction of TMJ, and osteoarthritis of TMJ were recorded and analyzed by K6-I system, then the data was used for diagnosis of anterior disc displacement with reduction in clinic.
RESULTS
A special kind of waveform was found in the electrosonography of sounds from anterior disc displacement with reduction repeatedly, and seldom or not in sounds from healthy joints, anterior disc displacement without reduction or osteoarthritis of TMJ. The diagnostic sensitivity of anterior disc displacement with reduction by using electrosonography analysis was 77.2% and specificity was 93.3% when compared with the clinical diagnosis based on clinical appearance and radiography evidence.
CONCLUSIONS
The special kind of waveform may be characteristic wave of sounds from anterior disc displacement with reduction of TMJ, which is useful for assistant diagnosis of anterior disc displacement with reduction in clinic.
目的
探讨颞下颌关节可复性盘前移位弹响的电声图特征及其在临床诊断中的价值。
方法
采用K6-I系统记录并分析正常颞下颌关节、颞下颌关节可复性和不可复性盘前移位以及颞下颌关节骨关节炎的弹响，将所得数据用于临床可复性盘前移位的诊断。
结果
可复性盘前移位弹响的电声图中反复出现一种特殊波形，正常关节、不可复性盘前移位及颞下颌关节骨关节炎弹响中少见或无此波形。与基于临床表现及影像学证据的临床诊断相比，电声图分析诊断可复性盘前移位的敏感度为77.2%，特异度为93.3%。
结论
这种特殊波形可能是颞下颌关节可复性盘前移位弹响的特征波形，有助于临床辅助诊断可复性盘前移位。
