耳管撮影法（Otosalpingographia）に就て

　耳管に造影劑を注入し，そのレ線像を撮影して耳管の形體及び機能の判別や耳管疾患の診斷に役立たしめようとする試みは既に可成以前から行われている。

　しかし之等は全部外國の文献によるもので我が國においては現在まで殆んど未だ用いられていない。

SUZUKI and associates develop a procedure which they call, Oto-Salpingography, in which the auditory tube by instillation of molyodol is made visible on X-Ray picture. A special bifurcated canula is devised and used for this instillation; the position of the head, besides the usual Renaud's position, is held in such a way as to bring the auditory tube into a straight line. There seem to be no untoward reaction in connection to use of this agent except, one case in particular, the opaque material proceeded into the mastoid air cells through the antrum and an examination of the patient a month later showed the opacity to be in an identical position without any change whatsoever. From the standpoint of physiology of the mastoid air cells an accident of this nature should be avoided with utmost care. With patients whose tympanic membranes are ruptured the opening may be taken advantage of for a portal of instillation with use of a syringe provided with a rubber tubing tipped with an olive.
