[A retrospective study evaluating effectiveness of different TMJ arthroscopic techniques for discal displacement with or without reducing]
The three arthroscopic techniques were particularly method I(lysis and lavage),method II(disc repositioning and sclerotherapy plus method I),method III(traction,fixation plus method II) in order to make comparative study.The distributions between the 76 joints and three techniques were:14 joints in method I,31 in II,and,31 in III.The total follow-up was 30m(6-84m),and the total success rate was 73.7%(53/76).The mean follow-ups were particularly:28.6m in method I,38.4m in II.and,74.2%(23/31) in III,particularly.There were no statically significance between I and II.In disc displacement with reducing,there were no statically significance between method II(18/20) or III(14/15) and I(1/40),and no statically significance between II and III.In disc displacement without reducing,there were no statically significance between method I(6/10)and II(8/11) or III(9/16),or between II and III.Conclusions were that II or method III was effective on disc displacement with reducing,and that it don't make clear for any one of three methods to be more effective on disc displacement without reducing.
