 Niho and his associates report on interesting findings in pathological changes that have been observed upon bones and mucous membranes in the diseased paranasal sinus. Histological preparations in this study embrace 45 specimens taken from 40 maxillary sinuses and 48 from 34 ethmoids. It is noted that, in disease conditions, ciliated mucous membranes are denuded of the cilia; vascular walls are markedly thickened by firotic hypertrophy. Majority of bone specimens show evidence of osteitis and among them 24 show areas of bony necrosis and sequestration. Basing upon these findings the authors assume that such histological changes contribute important determining factors for onset, progress and prognosis of paranasal sinusitis which, when well established, would require expedient choice in the method of treatment. Particularly, with presence of sequestration treatments, which would be dependent upon chemotherapy and/or use of biotics alone, without operative measures, might be expected to attain at the most temporary remissions only.
