自Kleinsasser开展显微喉镜检查法以来,许多喉显微器械已有了进一步的发展,该项技术几已成为耳鼻喉科的一项常规操作。近10年来,CO_2激光应用于喉显微外科也日渐增多,它具有下列的显著优点:(1)CO_2激光可使组织立即破坏,优于冷冻疗法要数星期才能使病变组织摧毁;(2)CO_2激光能使0.5～1.0 m m的血管和淋巴管闭塞,以保证手术无血和减少肿瘤细胞的扩散;(3)显微喉镜可提供良好的照明和放大术野,CO_2激光能在精确的控制之下操作,它与低功率的氦氖激光相配合,二者光束同轴,可以对准靶区。许多学者用10～15Watts功
Since laparoscopic microscopic examination of Kleinsasser, many laryngeal micro-instruments have been further developed, which has become a routine practice of otolaryngology. In the past 10 years, CO_2 laser has been used in laryngeal microsurgery and it has the following significant advantages: (1) CO_2 laser can immediately destroy the tissue, which can surpass freezing therapy and take several weeks to destroy diseased tissue; (2) CO_2 laser can occlude blood vessels and lymphatic vessels in the range of 0.5-1.0 mm to ensure blood-free operation and reduce the spread of tumor cells; (3) Microlaryngoscope can provide good illumination and magnification field, CO 2 laser can be used in accurate Under control, it cooperates with a low-power helium-neon laser that is coaxially aligned to the target. Many scholars use 10 ~ 15Watts work
