- Tubo-Tympanoaeroaerogaphy -

Abstract

Objective and quantitative analysis of the tubal dysfunction is receiving much attention as one of the last important problems left in the field of Tympanoplasty, and increasingly many studies are being made on this question lately. The recent studies on the Eustachian tube are classified broadly as follows:
X-ray methods (Suzuki, Compere, Aschan, Yamaguchi, Katagiri, S. Takahara, Miyazaki, and Ito)
Examination of foreign body expelling function (Rogers, Fukamachi, Kumazawa, et al., and Katagiri, et al. )
Acoustic methods (D ishoeck, Perlman, Tsukamoto, Tashiro, Elpern, Gyergyay, and Watanabe, et al. )
Impedance m ethods (Metz, Thomsen, and Holmquist)
Methods concerning tubal air movents
