【摘要】 对仅有单侧颞下颌关节症状的42例患者作双侧关节造影检查,并对症状、体征和造影结果之间的关系进行对照分析。结果发现在无症状侧关节同样存在关节内紊乱,其种类和发生率几乎与症状侧相同。为了避免信息的损失,对仅有单侧症状的颞下颌关节患者作双侧关节造影是必要的。更多还原

【Abstract】 TMJ arthrography is playing an important role in diagnosing the temperomandibularjoint disorder syndrome.However,TMJ arthrography is relative difficult for researchers.to do,thus the procedure is uauslly limited to the symptomatic side alone.As a specialanatomic structure,it is impossible for one TMJ that may not affect the other in theirfunctional movement.Hence the implicit assumption that the asymptomatic joint will benormal and it may coexist with a deranged contralateral partner,but it will be doulted.Inthe present article,patients with unilateral symptom undergone bilateral arthrographyhave been made comparetive analysis among the symptom,sign and arthrographic resul-ts.This study shows only rely on the chief complain,and clinic sign can’t present thebilateral TMJ conditions,symptomatic side arthrographic exam which may lost some usefulinformation.The results show that nearly 95% of both symptomatic and nonsymptomaticTMJs examined have arthrographic evidence of internal derangement.By using of bilateralarthrography,it is helpful for us to diagnose the pathogenic changes of both TMJ.更多还原
