背景：第3磨牙拔除过程可能引起周围软组织不同程度的损伤。由于超声波和超短波均属于热疗的范围，可以使组织温度升高，有助于提高软组织牵伸的治疗效果。目的：比较软组织牵伸配合超声波、超短波改善第3磨牙拔除后张口受限及疼痛的效果。方法：选取确诊为第3磨牙拔除术后致颌面部疼痛和张口受限的患者16例，采用随机数字表法分为牵伸组与对照组，每组各8例。牵伸组患者接受超声波和超短波治疗后联合软组织牵伸；对照组仅进行超短波和超声波治疗。治疗1次/d，5次/周，连续治疗2周。结果与结论：经治疗后两组患者最大主动张口度均增大，疼痛明显减轻，颞下颌关节的功能显著提高；牵伸组张口度的改善显著优于对照组，颞下颌关节功能的提高显著优于对照组。结果说明超声和超短波治疗均能改善拔牙术后患者张口受限及疼痛症状，提高下颌功能状态；配合软组织牵伸治疗效果更好。

BACKGROUND:The third molar extraction may lead to different degrees of soft tissue damage. Ultrasound and ultrashort waves belong to hyperthermia, which can increase tissue temperature and improve the therapeutic efficacy of soft tissue stretch. OBJECTIVE:To observe the effects of soft tissue stretch combined with ultrasound and ultrashort wave therapy for patients who were recently diagnosed with trismus and pain folowing third molar removal. METHODS:Sixteen patients with trismus and pain after third molar removal were randomly divided into two groups: patients in stretch group received soft tissue stretch with ultrasound and ultrashort wave therapy, while those in control group received only ultrasound and ultrashort wave therapy. Patients received the treatment five times per week, totaly for 2 weeks. RESULTS AND CONCLUSION:It was found that after treatment pain was significantly reduced at the temporomandibular joint, and the range of maximum active mouth opening increased significantly. The improvement in mouth opening and temporomandibular joint function was better in the stretch group than the control group. These findings indicate that ultrasound and ultrashort wave therapy can improve symptoms of trismus and pain folowing third molar removal, and the combination of ultrasound and ultrashort wave therapy and soft tissue stretch therapy can achieve more effective results.
