title: [A prospective study evaluating effectiveness of TMJ arthroscopy for particular stages of internal derangement]
abstract: The purpose of this prospective study is to evaluate effect on particular stages of internal derangement by TMJ arthroscopy.According to Wilkes-Bronstein classification,the distributions between 81 joints and particular stages of ID were:25 joints in II stage,18 in III,24 in IV,and 14 in V.The total 81 joints were undergone by arthroscopic surgery,the total success rates of different stages of ID were:24/25 joints in II stage,16/18 in III,13/24 in IV,and 7/14 in V particularly.The success rates were no statically significance (P>0.05) between II stage and III stage or between IV and V or V stages.The conclusion is that these cases in II or III stages of ID choose arthroscopic surgery than those cases in IV or V stages.
