急性上顎洞蓄膿症に注入せるモルヨドール陰影像の興味ある1症例

　緒言

　慢性炎症のある上顎洞内に造影剤を注入して其の排泄状況をレ線的に追及観察し，洞粘膜氈毛上皮に就いて考察しているのはKiug, Müllerで，急性炎症の上顎洞内に造影剤を注入して其の排泄状況を観察しているのは私共の臘捗する範囲ではProetzのみである．即ちProetzは急性炎症治褪後の上顎洞内に注入された造影剤の排泄状況を観察して，其れの著明な遅延を認めており，氈毛上皮を重視している．

　最近私共は急性上顎洞蓄膿症を起した1症例にて，幸ひ炎症を起す前の正常状態に於ける上顎洞内のモルヨドール陰影像（以下モ像と略す）並びに其の排泄状況を観察し，次いで炎症を起しているもの，更に炎症消褪後の上顎洞に於ける其れ等を観察し，之等3者のモ像並びに其の排泄状況を比較観察し，洞粘膜の氈毛上皮に就いて考察する時，夫々極めて特異的な，興味のある実験成績を得たので，茲に報告して御批判を仰ぎ度いと考へている．

ISHIKAWA attempts to investigate, by means of introducing moliodol into tne maxillary sinus and making series of rcentgenographic studies, the capacity of the sinus to empty itself of the contents under normal and varisous diseased conditions.

(1) In the normal sinus serial study of tne casted shadow was imperfect in its contour and the con-tents were thoroughly emptied at the end of the period of 1 week.

(2) In acute sinusitis the shadow was perfect and at no time were the contents completely emptied. (Infectious stage)

(3) In the period following immediately after the subsidence of acute stage the casted shadow was, again, imperfect but, the emptying was much de- layed. (Convalescent stage)

(4) Therefore, it may be assumed that recovery of the functional capacity of the sinus mucous mem- brane following an attack of acuts sinusitis is de- layed beyond the period when clinical symptoms are no longer seen.
