  • Title: A brief review of the use of both tympanometric pressure equalization and middle-ear function in assessing eustachian tube patency.
    Author: Givens GD, Seidemann MF.
    Journal: J Aud Res; 1983 Jul; 23(3):149-56. PubMed ID: 6680719.
    Abstract:
    This paper reviews recent studies on the tympanometric assessment of Eustachian tube patency involving the traditional technique of assessing pressure equilibration plus the analysis of changes in middle-ear ability to transmit energy through its system (middle-ear function). Normative data in the literature on 89 pediatric ears and 48 adult ears are discussed. The data illustrated a significant loss of information if pressure change is measured without consideration of middle-ear function change. Recommendations for the clinic are given and the need stated for extending such work to the pathological ear.
