Abstract
In the treatment of empyema in the maxillary sinus different preparations with sulfa or antibiotics have in the last 20 years been instilled after rinsing out the pus. Over 1500 empyemas have been treated. In the last 5 years only erythromycin-Abbott mixture has been used on a patient material comprising 841 maxillary sinuses. Of these, 55 per cent (459 cases) have healed up with one rinsing and 82 per cent (691 cases) with at the most two rinsings. Sinuses that have been rinsed more than twice have as a rule been endonasally trepanned according to Ostrom (17% or 141 cases). In only 2 cases (0.1%) has radical operation according to Caldwell-Luc been necessary. Erythromycin-Abbott mixture, which has a tolerable taste, has proved to be a suitable preparation for instillation in the maxillary sinus. No allergic or other side-effects have occurred in this material.
