The objective of this study is to classify the diseased mucous membrane of chronic maxillary sinusitis histopathologically, and to observe the interrelations between each histopathological changes found in the diseased sinus membrane in chronic maxillary sinusitis.
For this purpose, we examined 66 specimens microscopically which were taken from antrums of patients who had been operated radically in the college hospital for chronic sinusitis.
Specimens were stained with H-E for the general inspection, with PAS and Alcian blue-PAS for the glandular state, and with Weigert van Gieson for the connective tissue fibrosis. The obtained results were as follows:
I. The most frequent histopathological type was fibrotic(18 cases-27.3%) and the least was edematous(,4 cases-6.1%)
The infiltrative type was 13 cases-19.7%.
The edematous-fibrotic type was 7 cases-10.6%.
The edematous-infiltrative type was 6 cases-9.1%.
The infiltrative-fibrotic type and mixed type were as respectively same 9 cases-13.6%.
2. ANTith the duration of the disease, the number of edematous type showed decreasing tendency and the number of fibrotic type showed increasing tendency.
3. The number of neutrophils and eosinophils showed increasing tendency with the degree of the edema, but decreasing trend with the degree of the fibrosis.
The number of piasma cell and lymphocyte was in reversed trend with the degree of edema and parallel trend with fibrosis.
4. Hyperplasia in epithelial change was in parallel trend with the degree of the edematous change and in antagonistic trend with the degree of fibrotic change, but goblet cell showed reversed trend.
Atrophic change in epithelium showed a gradual increasing tendency with the degree of edema and fibrosis.
5. There was no certain tendency in edematous and fibrotic change with glandular response and vascular change.
