An attempt to evaluate whether virus infection is involved in the pathogenesis of otitis media with effusion in children was undertaken with cytological observation of their middle ear fluids, twenty-one being mucoid and two serous of twenty-three ears. Despite the categorization of the fluids from chronic otitis media with effusions, the dominant type of inflammatory cell was neutrophil in all 23 ears. Multinucleated cells were observed in thirteen of 23 cases. These cells seemed to have arisen from epithelial cells of the middle ear mucosa. Therefore, it is suggested that some virus may be involved in the etiology of otitis media with effusion. In ten cases of blue ear drum, numerous macrophages, lymphocytes and red blood cells were seen in their fluids. The condition of blue ear drum appeared to be based on a delayed-type hyper-sensitivity reaction. However, the role of virus infection in blue ear drum cases is unclear. Therefore, further virus study of middle ear fluids from otitis media with effusions and the condition of blue ear drum should be carried out.
