ABSTRACT
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.
