中文摘要
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-9·947 kPa±8·854 kPa,闭口位压力平均为-6·475 kPa±4·147 kPa。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。
英文摘要
Objective The study aims to find outthe 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 patientswere collected. ANo.8 syringe needlewas used to pierce intothe 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 patientswith sud- den-onset, persistent, severe closed lock had significantly low negative intra-articular pressure in their affected temporomandible joints. The average pressureswas (-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.
