Contact Nd:YAG laser surgery is assuming a role of greater importance in endoscopic and open surgery, allowing coagulation, cutting, and vaporization with greater precision and safety. A synthetic sapphire probe allows a wider angle of irradiation and diffusion of low power laser energy (less than 5 W) using an interstitial technique for producing local hyperthermia. Sensors placed directly into surrounding tissue or tumor continuously monitor temperature, and a pertinent computer program produces a controlled and stable temperature (e.g., 42 degrees C) over a period of time (e.g., 20-40 min). The Laserthermia system (Surgical Laser Technologies, Inc., Malvern, PA), using the Nd:YAG laser, offers many advantages in the experimental and clinical treatment of carcinoma by local interstitial hyperthermia.
接触式钕钇铝石榴石激光手术在内镜手术和开放手术中发挥着越来越重要的作用，它能以更高的精度和安全性实现凝固、切割和汽化。合成蓝宝石探头采用间质技术产生局部高温，可实现更大角度的照射和低功率激光能量（小于5瓦）的扩散。直接置于周围组织或肿瘤中的传感器持续监测温度，相关计算机程序可在一段时间（如20 - 40分钟）内产生可控且稳定的温度（如42摄氏度）。使用钕钇铝石榴石激光的激光热疗系统（外科激光技术公司，宾夕法尼亚州马尔文）在局部间质热疗实验性和临床治疗癌症方面具有诸多优势。
