鼻粘膜炎症と体質をめぐる問題—（その5）慢性副鼻腔炎の疫学的研究と集団検診法の検討

THE RELATION OF NASAL INFLAMMATION TO CONSTITUTIONAL BACKGROUND (FIFTH REPORT) THE DIAGNOSIS OF CHRONIC PARANASAL SINUSITIS IN MASS EXAMINATION

　学童慢性副鼻腔炎に関する最近の系統的研究は名越^1），鈴木^2）らによつてなされているが診断方法の基準について明確な記載がなく，各自が各様の基準に従い，成績は一定せず，そのために比較研究に甚だ不便であつた。われわれは慢性副鼻腔炎の疫学的研究を行い慢性副鼻腔炎の発症頻度の地域差，栄養，気候，空気汚染，体質としての鼻含気腔の発育の関係を調査するに際し，診断方法に若干の検討を加えてみた。この場合まず手始めに調査しやすい学童を集団検診したためなるべく手数と時間費用がかからず，しかも副鼻腔炎の発見率のよいことを目標とした。

In making a diagnosis of chronic sinusitis in mass examination of patients various me-ans of approach, such as history taking, rout-ine nasal inspection, routine radiography and fluororoentgenography, were tested.

1) By history taking alone the diagnosis of chronic sinusitis is unreliable.

2) About one half of the total number in whom the sinus involvement was regar- ded to be slight by direct nasal inspec- tion showed the presence of chronic sin- usitis by x-ray examination.

3) In making mass examination fluoro- roentgenography proved valuable in esta blishing the diagnosis of chronic sinusitis.

4) The morbidity rate of sinusitis appeared to be 72.9% when x-ray alone was used in the diagnosis; 34.0% with direct na- sal inspections; and, 57.7% when all three methods were used in a combina- tion.
