本文指出目前声带手术方法的准确性、速度、止血等均受一定限制,如采用声带显微手术并联合应用二氧化碳激光(波长10.6微米,几乎能被身体组织完全吸收)可以克服以上缺点。在双目显微镜下操作,能准确地掌握切除深度与广度。作者给16只狗作了实验性手术(激光强度为30—40瓦,3毫米直径集光点,1/10—1秒脉冲)。隔1、2和3周后以双目显微镜复查声带各一次,而后杀狗取出喉部作组织切片检查。发现激光手术与清洁外 This article points out that the accuracy, velocity and hemostasis of vocal cord surgery are limited by the above methods. Vocal cord microsurgery combined with CO2 laser (wavelength 10.6 μm, almost completely absorbed by body tissues) can overcome the above shortcomings. Operating under a binocular microscope, can accurately grasp the depth and breadth of resection. The authors performed experimental surgery on 16 dogs (laser intensity 30-40 watts, spot diameter 3 mm, 1 / 10-1 second pulse). One, two and three weeks later, the binocular microscope was used to examine the vocal cords one time, and then the dog was removed to take the larynx for histological examination.
