Abstract
1) Two cases of sinusitis maxillaris neonatorum, 2 months old male and 15 days old female, were reported. In both cases, the radical operation of osteomyelitis and administration of antibiotics were performed, and results were successful.
2) Fifty cases of this disease, which were admitted in E. N. T. clinic of Kyushu University Hospital from 1907 to 1964, were statistically discussed with regard to sex, age, pathogenesis, route of infection, treatments.
3) The treatment of this disease has become easy by the application of antibiotics. But it should be noted that the tolerance of Staphylococcus aureus to antibiotics has been increased.
