緒言
慢性副鼻腔炎の場合,膿汁の排泄に鼻粘膜の線毛運動が大なる役目を果たすであろう事は容易に想像される。此の線毛運動を慢性副鼻腔炎の診断に応用せんとする試みが近時行われつつある。我が国に於いては,大藤,石川が40%モルヨドール3〜8ccをシユミツト探膿針で上顎洞に注入し洞内よりモルヨドールの消失する速度を「レ」線にて撮影し,其の排泄の遅速の度に依つて,慢性副鼻腔炎の有無を判定した。然し乍ら,此の方法には次の様な不利な点がある。
1)レントゲンを必要とする事
2)慢性副鼻腔炎の診断に少くとも3日以上を必要とする事。
GOTODA uses as a diagnostic adjunct for establishing premises for chronic sinusitis a heavy spray of pulverized zinc oxide into the nasal cavity. The zinc oxide powder sprayed over the nasal mucous membranes in thi maner will, by their inherent ciliary action, disappear invariably without a trace being left thereof by the end of a 20 minutes period. However, with patients whose sinus X-Ray show darkend shadows the agent thus used will remain unchanged in the nasal cavity even at the end of a 30 minutes period; with moderate shadows, at the end of 30 minutes, the agent is found only in areas below the interior turbinates; with light shadows, the results are much the same as those that are normal.
