Study to clarify the tissue acceleration of low power output laser irradiation

各种低功率输出激光器经常用于口腔区域。近年来，低功率输出激光器已广泛应用于临床，并成功应用于加速伤口愈合和疼痛控制。我们已经证明了低功率Nd：YAG激光和二极管激光（Ga-Al-As，810 nm）本研究为治疗神经系统疾病如下唇麻痹和面神经麻痹的患者提供了一种新的放射治疗方法。目的：探讨低功率Nd：YAG激光治疗小儿麻痹症的疗效。<Results>完全治愈9例，部分治愈13例，治愈不良或失败3例。13例完全治愈者和5例部分治愈者在首次治疗时出现症状即行激光治疗。部分治愈的13例中有8例在症状出现后几个月内进展。3例治愈不良或失败病例在症状出现后几年进行了初步治疗。完全治愈和部分治愈的病例大多数在治疗后1 ~ 2个月内治愈，但3例治疗效果差或失败的患者症状无明显变化。综上所述，症状出现后立即进行激光治疗是有效的，但症状出现后很长一段时间病情进展，则效果不佳。

Various low power output lasers are used frequently in the oral region. Recently, low power output lasers have been widely used in clinics, and successful application has been reported in the acceleration of wound healing and pain control.We have demonstrated therapeutic effects of low power Nd : YAG laser and diode laser(Ga-Al-As, 810nm) irradiation of patients with neurological diseases such as lower lip paralysis and facial palsy.We made the present study for the purpose of treatment of the facial palsy patients using low power Nd : YAG laser and the therapeutic results.<Results>9 cases were complete cured, 13 cases were partially cured and 3 cases were poorly cured or failures. All completely cured cases and 5 of the 13 partialy cured cases were given laser therapy as soon as symptoms occured in the initial treatment. 8 of the 13 partialy cured cases had progressed a few month after the symptoms had occured by the time of the initial treatment. 3 of the poorly cured of failure cases had progressed a few years after the symptoms had occured by the time of initial treatment. Most of completely cured and partially cured cases healed within 1 or 2 months after the initial treatment, but the symptoms of 3 patients whose results were poor or a failure revealed no remarkable change.To summarized the above, when laser therapy was conducted as soon as symptoms occured it was effective, but when the condition had progressed a long time after the symptoms had occured, it was not so effective.
