摘要
目的 了解突发性严重绞锁患者颞下颌关节上腔中的压力特点及其变化规律,初步探讨该类型颞下颌关 节紊乱病的治疗机理。方法 用关节内压测量仪通过穿刺针进入突发性严重绞锁患者颞下颌关节上腔,分别测量 张闭口位的关节上腔内压,记录其平均值和变化规律。结果 突发性严重绞锁患侧关节上腔开口位压力平均 为_9.947kPa±8.854kPa,闭口位压力平均为_6.475kPa±4.147kPa。结论 突发性严重绞锁颞下颌关节上腔开闭 口位压力明显降低,并有独特的变化规律。
Objective The study aims to find out the fluctuating curve of the intra-articular pressure in temporomandibular joint with sudden-onset, persistent, severe closed lock and discuss the mechanism of its formation. We also investigate the effects of the arthrocentesis.Methods 20 affected sides in 16 patients were collected. A No.8 syringe needle was used to pierce into the upper compartment of TMJ. The pre-arthrocentesis intra-articular pressure was measured by the pressure transducer via the flexural rigid tubing at open and close bite. The curve and mean value were documented during the operation.Results The patients with sudden-onset, persistent, severe closed lock had significantly low negative intra-articular pressure in their affected temporomandible joints. The average pressures was (-9.947±8.854) kPa at open bite and (-6.475±4.147) kPa at close bite.Conclusion The TMJs with sudden-onset, persistene, severe closed lock has particular characters on etiology and clinical behavior. Arthrocentesis is one of the effective treatments to the diseases.
