摘要
目的：观察用硬化剂注入翼外肌下头治疗颞颌关节复发性脱位（ＲＴＭＪＤ）效果。方法：以标有长度的７号注射针头于髁突颈稍前方平行髁突横轴进行深达２．０ｃｍ～２．２ｃｍ，缓慢后退１．０ｃｍ～１．２ｃｍ，并同时注入０．６ｍｌ～０．８ｍｌ硬化剂后拔针。结果：经治疗的２５例３２例ＲＴＭＪＤ平均随访３年，治愈率达９４％；ＴＭＪ许勒位片显示治疗后的髁状突前伸范围明显小于治疗前（Ｐ＜０．０１），平均缩短４ｍｍ左右。结论：该方法治疗ＲＴＭＪＤ简单方便，疗效可靠。其机制可能是硬化剂破坏了部分肌纤维，削弱了大开口时髁突所受的前拉力，缩小了髁突的前伸运动范围而达到治疗目的。
Objective: To study the effects of sclerosing agent in the treatment of recurrent TMJ dislocntion. Methods:The neck of mandibular condyle was outlined. The puncture point was just in front of the condyle neck. A needle with scale distance is directed inwards, parallel to the horizontal axis of the condyle, reaching the depth of 2.0 to 2.2 cm and then 0.6 to 0.8 ml of the sclerosing agent was injected slowly while the needle was been withdrawing up to the depth of 1.0 to 1.2 cm. Results:Twentyfive cases with 32 sides of TMJ dislocation treated with the sclerosing agent were followed up for mean 3 years. A high success rate(94%) was obtained. Xray films of TMJ in Schuller position demonstrated that forward movement extent of the condyle after treatment was about 4 mm less than that before treatment(P<0.01). Conclusion: This technique is effective and simple in the treatment of TMJ dislocation since the muscular fibres of the lower pterygoid may be destroyed by the sclerosing agent, the excessive pull of the muscle at the condyle can be decreased and the forward movement of the condyle can be limitted.
