Perhaps the best way to clarify my position for Dr. Magian is to consider the benefit/cost ratio of impedance audiometry for routine screening of children. (As a research tool I support its use strongly.) Let us first consider the benefit of routine screening and how firmly established this benefit is. The major benefit claimed is that tympanometry identifies eustachian tube dysfunction with greater sensitivity than other techniques. To quantitate this benefit one needs to know the proportion of children identified by this, but not by other, techniques.
