单侧颞下颌关节疼痛和功能失调双侧关节造影检查的重要性

Bilateral Arthrographic Evaluation of Unilateral TMJ Pain and Dysfunction

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。

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.
