Abstract
With regard to the cases which had been operated under the diagnosis of the odontogenic maxillary cyst at the Department of Dentistry and Oral Surgery of the Nagoya National Hospital during the past 11 years, we made the clinico-statistical and the histo-pathological examination and obtained some findings. Herewith we present the results of the findings obtained.
There were 34 cases including 15 cases of the postoperative maxillary cyst and 19 cases of the odontogenic maxillary sinusitis.
With respect to the incidence among different age groups, it was most frequent in subjects from 40 to 49 years old, and they suffered from the postoperative maxillary cyst in 6 case (40.0%) and from the odontogenic maxillary sinusitis in 5 (26.3%).
In view of the odontogenic maxillary sinusitis, on the other hand, the ciliated epithelium was found numerously in the epithelial tissue, and the tendency to the edema and infiltration of the subepithelial tissue was recognized, and the glandular tissue existed at a high rate, comparing to the postoperative maxillary cyst.
