[Bony changes in chronic odontogenic maxillary sinusitis].

The authors undertook histological studies on the bone of the facial wall of the maxillary sinus from 64 out of 84 patients who had been operated on for chronic maxillary sinusitis of dental origin in the course of 16 months. Apart from mucosal changes, the specimens from 16 patients showed also osseous changes in the form of periosteal reactions of varying extent. With regard to therapy, it is concluded that patients suffering from odontogenic sinusitis should for preference be treated by surgical intervention, because the conservative treatment will not necessarily result in complete healing.
