耳管狭窄症の治療法に就ては古くから種々の方法が考案発表されている.その中で最近特に我々の注目を惹くのは.Croweによつて唱導された耳管扁桃腺の放射線療法である.1939年にJ.A.M.A.に発表された原著がそれである.爾来約10年間にアメリカ,イギリス,カナダ,日本等の諸国に於て続々と追試が行われ,放射線療法もラヂウム及びラドンを用いる方法からレントゲンを用いる方法にまで拡張された.その目的とする所は,先天性に或は後天性に炎症の結果として発生する処の耳管扁桃腺を,放射線によつて萎縮させて耳管狭窄度を減じ,その結果聽力の恢復を計ろうとする処にある.私は耳管狭窄症患者に対して本療法を実施し,2.3の興味ある知見を得たので此処に報告して先輩諸賢の御批判を仰ぎたいと思う次第である.
KITAGAWA treated 50 cases, 78 eare, of sten-osis of auditory tube by means of radium and/or roentgen-ray irradiations. Out of 78 eares catarrhal affections numbered 70. Patient's ages ranged from 5 to 67.
The results of the therapy were observed with audiometric readings; inspections of the tubal ope-nings were made through nasopharyngoscope. The author comes to the following conclusions:
(1) Irradiation therapy for tubal stenosis proved to be effective in 46 per cent of adult cases while in children, it was still higher, by 84 per cent.
(2) with radium irradiation children and adults alike showed improvements in 66 per cent of cases; roent gen-aays, 65 per cent. There were practically no difference between the two.
(3) That to make proper diagnosis or prognosis of tubal catarrhal inflammation naso-phaTyngoscope proved to be an indispensable armamentarium.
(4) That in tubal stenosis where tubal tonsils are found concurremly hypertrophied with palato-phar-yngeal tonsils, eithet adenotomy alone or the com-bined adenotonsillectomy should be performed before instituting irradiation therapy.
