抄録
The structure of the opening of the Eustachian tube of 702 cases were obserbed with fiberoptic endoscope, and the relationship between the difficulty in ear douche by Eustachian tube catheteriza- tion and the shape of the orifice was discussed.<br>The shape of pharyngeal orifice of the tube was classified into two types.The one which is well-known as ordinary shaped was named as type I, while the other which has an arched upper edge by torus tubarius was termed as type II.<br>Type II orifices were found more frequently(54.3%) than type I.Insertion of a catheter was difficult in type II ones because the tip of catheters was apt to slip down from the tubal elevation.<br>Moreover, anatomical irregularities in the nasopharynx, which is observed quite often, seem to be a factor of difficulties in douching the tube.In case of a failure in ear douches, it is necessary for us to detect its cause, and in case of type II orifice, the way of probing the orifice should be changed. I have treated some patients who were suffered from tubal obstruction with an injection of remedies into the auditory tubes, observing with remodelled Olympus NPF-S3 fiberscope, and have got a good result.
