摘　　要：为探讨Ｈｅ－Ｎｅ激光中耳内照射前后鼓室粘膜表面的超微结构变化，我们对９例、９耳慢性中耳炎患者微潮鼓室粘膜进行低功率Ｈｅ－Ｎｅ激光照射，每次１０分钟，１０次一疗程，每日一次照射治疗。于照射前、后取鼓室粘膜，进行扫描电镜观察。结果发现，经Ｈｅ－Ｎｅ激光照射后，表面结构趋向完整，上皮细胞彼此间排列较照射前紧密，无纤毛细胞间表面可见微绒毛。并发现激光照射后炎细胞消失，鼓室粘膜形态趋向正常。提示弱激光（Ｈｅ－Ｎｅ）治疗中耳炎是可推广的。In order to study the effects of He Ne laser on the mucosa of middle ear, mucosae from 9 patients with chronic otitis media, all of whom had slight damp eardrum, were irradiated by low power He Ne laser ten minutes per day for ten days.Specimen was taken before and after irradiation and observed under scanning electron microscope. It was found that the surface structure of the mucosa was more complete, the arrangement of the epithelial cell was closer together and micro villi arose among the noncilliated cells after irradiation. The inflammatory cells disappeared and the morphologic structure of the mucosa appeared normal. These data provided evidence of therapeutic effects of the lower power He Ne laser irradiation on patients with chronic purulent otitis media.
