Aspergillosis of the maxillary sinus. Clinical and histopathological features of 4 cases and a review of the literature.

Four patients with aspergillus maxillary sinusitis are reported and a review of the literature on aspergillus paranasal sinusitis during the last 10 years is presented. The patients had symptoms and X-ray findings similar to a chronic bacterial sinusitis. One patient had been operated upon 6 years previously due to a chronic sinusitis and 3 of the patients had been treated with broad-spectrum antibiotic drugs. Caldwell-Luc operations were performed, also to exclude malignant tumours. The aspergillus etiology of the sinuitis was discovered in routine stained sections by histo-pathological examination of the sinus mucosae. No recurrence of the fungus infection occurred after the Caldwell-Luc operation, which was valuable for the correct diagnosis as well as being the best suited therapy.
