Tympanometry in three-year-old children. A cohort study on the prognostic value of tympanometry and operative findings in middle ear effusion. 1979

M Fiellau-Nikolajsen, and J Lous

The operative findings in a homogeneous, preoperatively followed population of 46 3- to 4-year-old children with middle ear effusion treated by adenotomy and paracentesis were correlated with the results of pre- and postoperative tympanometry. Factors of prognostic value were only the immediate type of tympanogram and the quantity of the middle ear effusion, not its viscosity. The combination of the determinative factors divided the material into four groups showing a different course through a 6-month postoperative follow-up. A flat tympanogram and impacted fluid spelt the poorest prognosis, with about 60% recurrences. The influence of the results upon a differentiated treatment of secretory otitis media in the younger age groups is outlined.

D000158	Acoustic Impedance Tests	Objective tests of middle ear function based on the difficulty (impedance) or ease (admittance) of sound flow through the middle ear. These include static impedance and dynamic impedance (i.e., tympanometry and impedance tests in conjunction with intra-aural muscle reflex elicitation). This term is used also for various components of impedance and admittance (e.g., compliance, conductance, reactance, resistance, susceptance).
