Outline of Final Research Achievements

We developed a new Eustachian tube function test device by measuring the sound pressure in the external auditory canal using vocal sounds. The developed Eustachian tube function test device showed a significant difference in vocal sound between the control group without Eustachian tube openings and the Eustachian tube openings group through various usefulness and validity studies, and succeeded in demonstrating its usefulness and validity as a new diagnostic device for Eustachian tube openings. The results show the potential of this device as a new Eustachian tube function evaluation device.

Academic Significance and Societal Importance of the Research Achievements

今回の研究結果により、新たな耳管機能を評価する検査機器としての有用性が示された。このことは、現在感度特異度ともに満足のいく結果とはなっていない従来の耳管機能評価方法に対して、その診断率向上のためのひとつの一助となる可能性がある。今後はこの研究結果を踏まえて、この検査方法の普及に努めることが必要であると考えられた。
