目的 采用醋酸强的松龙作关节上腔或关节下腔注射1～3次,针对治疗观察疼痛、弹响或杂音和开口障碍三大症状的疗效.方法 86例颞颌关节紊乱综合征患者(TMJDS)中,关节上腔注射治疗Ⅰ类翼外肌亢进型的弹响开口过大症状22例,Ⅱ类关节囊松弛、盘突失调的可复性盘前移者40例,Ⅲ类关节窝、关节结节骨质改变者8例,关节下腔注射治疗Ⅲ类髁突骨质改变者16例.结果 关节腔注射醋酸强的松龙对治疗TMJDS的Ⅰ、Ⅱ、Ⅲ类的弹响杂音有效治疗率分别为90%、87.5%、70.8%.对Ⅱ、Ⅲ类的疼痛不适的有效治疗率分别为72.2%、75%;对Ⅰ、Ⅱ、Ⅲ类的开口障碍治疗有效率分别为44.4%、50%、46%.结论 该疗法对TMJDS三类之弹响杂音症状的疗效较为满意,对三类之疼痛症状的疗效一般,对三类之开口障碍症状的疗效欠佳,提示对TMJDS患者以弹响杂音为主要症状的治疗首选此法较好.“,”Objective To investigate the clinical effect of aticulare injection with prednisolone acetate to treat TMJDS.Methods Eighty-six patients were adopted in this study in which 22 cases with wing-tpye I muscle hyper-snapping or open excessive symptoms,40 cases Ⅱ-type with flabby joint capsule and dysfunction of articular dise.8 cases type Ⅱ with fossa and joint improvement of bone nodules were received injection in superior articular cavity.16 cases of type Ⅲ condyle bone changes treated with inferior vena joint injection.Results Intra-articular injection of prednisolone acetate in treatment of TMJDSI,Ⅱ,Ⅲ class snapping noise efficiency were 90%,87.5%,70.8% respectively.For type Ⅱ,Ⅲ types of difficulty to open showed efficiency of 44.4%,50%,46%.Conclusions zintra-articular injection of prednisolone acetate in treatment of TMJDS,snapping noise of the three types were more satisfied;the pain symptoms had general effect;Obstacle in opening showed poor effects suggested that the methods to treat patients with TMJDS of snapping noise as the main symptoms is efficient.
