title: Comparison of pre- and post-operative bacteriology of chronic ears.
abstract: The over-all distribution of the pre-operative bacteria of 806 ears and the post-operative bacteria of 109 post-operatively moist or discharging ears correlated very well, the only clear difference being the detection of diphtheroid bacilli more often post-operatively than pre-operatively. When comparing the pre- and post-operative bacteriology of 109 post-operatively infected chronic ears which had undergone radical surgery and obliteration with Palva flaps (and which were drawn from a group of 806 ears originally operated on and followed yearly for 5-14 years) it was noticed that Pseudomonas aeruginosa and Proteus sp were cultured more often post-operatively than pre-operatively in the same ears. Statistically, other bacteria were not found to be significantly present in the same ears.
