Investigations on the Tubal Function and Measurement of the Middle Ear Pressure in Pressure Chamber
Knud Anker Thomsen · Acta Oto-Laryngologica · 1958
In three other studies (16, 17, 18) the writer has described the applicability of impedance measurement in examination of the tubal function, and reported the results of the examination of 100 normal tubae with this method.To make the following more readily understood the principle of the method previously used may be briefly summarized.
