目的采用 SUNDOM半导体激光加电脑中频对颞下颌关节功能紊乱综合征 40例患者进行综合物理治疗。方法另以 32例单一用半导体激光治疗患者为对照组进行疗效比较。结果观察组 40例患者中痊愈 20例，好转 29例，无效 3例，总有效率 92.5％；对照组 32例患者中痊愈 9例，好转 16例，无效 7例，总有效率 78.12％。观察组疗效明显优于对照组。结论表明半导体激光并电脑中频综合治疗颞下颌关节功能紊乱综合征，是一种较理想的治疗方法。 Objective To use SUNDOM semiconductor laser plus computer IF to treat 40 patients with temporomandibular disorder. Methods Another 32 patients with single semiconductor laser treatment for the control group were compared. Results The observation group of 40 patients recovered 20 cases, 29 cases improved, 3 cases ineffective, the total effective rate 92.5%; control group of 32 patients recovered 9 cases, improved in 16 cases, 7 cases, the total effective rate was 78.12%. Observation group was significantly better than the control group. Conclusions show that the semiconductor laser and computer IF treatment of temporomandibular joint dysfunction syndrome is a more ideal method of treatment.
