上顎洞の機能検査に就て

　第1章　緒言

　日常鼻疾患を診断するに際し，常に考慮すべきものの1つは副鼻腔粘膜の機能状態である．而して上顎洞は節骨蜂窩と共に副鼻腔中極めて重要な地位を占め，洞内粘膜の適確なる罹病状態の判断なくしては副鼻腔炎の明確な診断は下し得ないのである．

　斯る意味に於て，健康並に種々の罹患に於ける上顎洞に中鼻道乃至下鼻道穿刺に依り40％モルヨドール液（以下「モ」液と略す）も注入し，其モ液陰影像（以下「モ」像と略す）並に排泄状況をレ線的に観察し洞内機能状態を検査せんと各種の実験を試みた．来従造影剤注入に依るレ線的研究は単に洞の形態学的研究であつたが，其後Ed. king^1）（1935），Er. Müller^2）（1938）を始め最近ではProetz^3）（1947）等が洞内異物である造影剤の排泄状況をレ線的に追究し，洞内粘膜の機能状態，殊に氈毛上皮の氈毛運動に就て考察している．

　Dano and Ishikawa maintain that in making examination of nasal diseases the foremost thought should to placed upon consiperation of the functional status of the paranasal sinuses. Two hundred maxillary sinuses which included the normal and the diseased such as affected with catarrhal inflammation, acute and chronic infection, argyrosis, operative removal of part or whole of sinus mucous membranes, and with lack of air circulation within the cavity because of previous laryngectomy are studied with roentgenogram by use of radio opaque molyiodol, noting in particular the established con. ditions of the diacharge and corresponding functional state. In some the stupy included examination of biopsy specimens.

　Thus, a clear cut view of the features that characterized the normal or the, diseased state of the sinus cavity was obtained.

　It is also evident that the chief means by which exudates are expelled from the sinus cavity are dependent upon the cilliary activity of the cilliated cells and when intrasinus air circulation is unhindered the function of expulsion appeared to be further aided thereby.
