[Aspergillosis of the maxillary sinus (author's transl)].

Aspergillosis of the paranasal sinuses becomes more and more important. 5 special cases and their histological findings are described. All of them showed unilateral chronic sinusites of long duration. Surgically there were found crumbly cheese-like substances in the sinuses, which corresponded to old fungal masses. The diagnosis was only possible by histological examination, usual staining methods were sufficient. Contrary to the opinion that consumptive basic illness or defects of the immunity system - also caused by therapy - would be a disposing factor for the fungal infection it has now been demonstrated that such cases are to be expected also spontaneous. Anatomical abnormities of the nasal space can favour the affection. Radical operation was the successful therapy.
