Importance of eustachian tube function in middle ear surgery. 1998

M Tos
ENT Department, Gentofte Hospital, University of Copenhagen, Denmark.

Poor eustachian tube function plays a major role in the pathogenesis of chronic secretory otitis media. This is illustrated by epidemiologic studies of secretory otitis media and long-term studies of treated secretory otitis. Evaluation of hearing results demonstrate that effective preoperative and postoperative tubal function is highly important for good surgical outcome in cases of chronic otitis and cholesteatoma.

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).

D014432 Tympanic Membrane An oval semitransparent membrane separating the external EAR CANAL from the tympanic cavity (EAR, MIDDLE). It contains three layers: the skin of the external ear canal; the core of radially and circularly arranged collagen fibers; and the MUCOSA of the middle ear.

D016009 Chi-Square Distribution A distribution in which a variable is distributed like the sum of the squares of any given independent random variable, each of which has a normal distribution with mean of zero and variance of one. The chi-square test is a statistical test based on comparison of a test statistic to a chi-square distribution. The oldest of these tests are used to detect whether two or more population distributions differ from one another.
