Tympanometry as a screening test for treatable hearing loss in the elderly.

One hundred and fourteen adults with hearing loss, but without otorrhoea, were studied with the aim of establishing whether tympanometry could be used as a screening test to identify potentially treatable aural pathology. Tympanometry was compared with independent otoscopy. No middle ear pathology likely to be of significance in an elderly person was found in ears with a normal tympanogram. All ears with significant pathology gave an abnormal tympanogram, and in addition there was a false positive rate of 6.8%. We suggest that elderly patients with dry ears and a normal tympanogram could be fitted with a hearing aid without specialist otological examination.
