Abstract

In order to study the effects of He-Ne laser on the mucosa of middle ear mucosa from 9 patients with chronic otitis media, all of who 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 integral, the arrangement of the epithelial cell was closer together and microvilli arose among the noncilliated cells after irradiation. The inflammatory cell disappeared arid the morphologic structure appeared normal. These data provided the therapeutic evidence for the lower power He-Ne laser irradiation on patients with chronic purulent otitis midia.
