口内、口外手法复位在颞下颌关节急性前脱位中的临床疗效观察

目的：：观察口内、口外手法复位在颞下颌关节急性前脱位中的临床疗效。方法：随机数字表法将98例颞下颌关节急性前脱位患者分为口外和口内手法复位组,每组49例,评价组间复位成功率、复位成功时间、疼痛程度、收缩压( SBP)、舒张压(DBP)、心率(HR)变化和患者满意度。结果：口外手法组复位成功率(95.92%)及患者总满意度(76%)均高于口内手法组(81.63%)、(66%)；口外手法组复位成功时间(3.91±0.55) s、疼痛程度(3.51±0.25)均低于口内手法组(5.57±0.51) s、(6.6±0.21),且口外手法组SBP、DBP、HR,变化程度小于口内手法组SBP、DBP、HR,差异均有统计学意义(P<0.05)。结论：颞下颌关节急性前脱位时采用口外手法复位比口内手法效果更好。

The study of extraoral manual reposition approach in the treatment of acute anterior dislocation of tem-poromandibular joint

Objective:To observe the clinical effects of extraoral manual reposition approach in the treatment of acute anterior disloca-tion of temporomandibular joint. Methods:98 patients with acute anterior dislocation of temporomandibular joint were divided into 2 groups(n=49) by random digit table and treated by manual reposition through intraoral and extraoral approach respectively. The suc-cess rate, success time, patient pain during treatment, SBP, DBP, HR and patient satisfaction were evaluated respectively. Results:The success rate(95. 92%) and the patient satisfaction rate(76%) of extraoral method group were higher than those of the intraoral method group (81. 63% and 66%);success time(3. 91 ± 0. 55)s and patient pain during treatment(3. 51 ± 0. 25) in extraoral method group were less than those in the intraoral method group(5. 57 ± 0. 51) s and (6. 6 ± 0. 21)]. The degree of changes of SBP, DBP and HR in extraoral method group were less than those in the intraoral method group(P<0. 05). Conclusion:Extraoral manual reposi-tion approach is more effective than intraoral approach in the treatment of acute anterior dislocation of temporomandibular joint.
