[Experiences with oto-rhinogenous brain abscesses (author's transl)].

The results and conclusions of 43 surgical interventions performed on account of oto-rhinogenous brain abscess are reported. In these patients the infection of brain substance occurred in two ways: 1 by contact propagation and 2. per venous reflux, associated with thrombosinusitis. In the 1. the brain abscess was accompanied by purulent meningitis and the majority of the patients died during the postoperative period. In the 2, the patients operated on account of cerebral abscess developed per venous reflux, improved and became health. In order to get more exact localisation of the abscess there are different radiological auxiliary methods available: in supratentorial abscesses exact informations can be obtained by carotid angiography, while in the cases of infratentorial abscesses the pneumography is helpful, notwithstanding the latter is not fully harmless. As the ideal operative solution the total exstirpation of the abscess with undamaged capsule can be proposed.
