 The middle ear discharges from acute otitis media were cultured and the antibiotic sensitivity of the pathogens were tested. A marked bulging ear drum was diagnosed as an indication for paracentesis. The discharge following this procedure was cultured in 174 cases among the children whose ages ranged from 0 to 12 years. In this manner 186 ear cultures were obtained ; 14 ears were sterile while 172 ears showed positive pathogens. The bacterial distributions were found to be diplococcus pneumoniae, 30. 6% ; staphylococcus aureus, 6. 6% ; group A beta streptococcus, 13. 9% ; hemophilis influenza, 7. 5% ; and,neisseria catarrhalis, 2. 1%. Judging from the antibiotic sensitivity of the pathogens, the relation between the causative organism and the age of the patients and the characteristic peculiarities of the antibiotics, cephalosporine and AB-PC were considered to be the optimal antibiotics to be employed among children in treatment of acute otitis media.

 The effects of paracentesis on the clinical course of acute otitis media were investigated. There was no difference in the recovery time in acute otitis media whether paracentesis was performed or not. However, there were more ears showing retraction of the ear drum at the time of recovery, 57. 5%, than those with paracentesis, 33. 3%, Five of these retracted ear reverted to secretory otitis. In this era of antibiotics paracentesis appear to have no therapeutic advantage in the treatment of otitis media.

 However, paracentesis should be performed in order to obtain information on the causative pathogens and their sensitivities to particular antibiotics.
