Abstract
1292 patients had tonsilectomy or adenotomy or both of them at this clinic during 1954 to1958. Questionaries were sent to the all of the patients, and 585 cases answered them andwere investigated. Further effects of the operations were generally satisfied, however, inninety-eight cases, they were suffered from diseases after the operations.
In two cases aged 5 and 7, they were suffered from poliomyelitis and they were slight.
The intervals of the onsets of the disease and the operations were ; in one case 3 yearsand the other 1 year and 2 months.
Therefore, from these two cases, it was difficult to find any relation of the effects oftonsillectomy to the incidence of poliomyelitis.
According to american literatures, authors consider that it is better to avoid theseoperations during epidemics of the disease.
